U.S. EPA Designation

EPA

Rupprecht & Patashnick TEOM® Series 1400 and 1400a PM-10 Monitors
EPA Designation No. EQPM-1090-079

The United States Environmental Protection Agency (U.S. EPA) has designated the
Rupprecht & Patashnick TEOM® Series 1400 and 1400a PM-10 Monitors as an
equivalent method for the determination of 24-hour average PM-10 concentrations in
ambient air. For use as a designated equivalent method, the TEOM® Series 1400 and
1400a PM-10 Monitors must be operated with a Rupprecht & Patashnick PM-10 Inlet
(00506-0000), a modified Rupprecht & Patashnick PM-10 Inlet (57-004742) or a
Sierra-Andersen Model 246b PM-10 inlet, a flow rate of 16.7 liters per minute, teflon-
coated glass fiber filter cartridges, the total mass averaging time set at 300 seconds,
and the mass rate/mass concentration averaging time set at 300 seconds.

The use of the Rupprecht & Patashnick (R&P) PM-10 inlet was approved by U.S. EPA
on December 9, 1990.

On September 1, 1993 the U.S. EPA approved the operation of the Series 1400 and
1400a monitors on a case-by-case basis at lower temperature settings under winter-
time conditions. Requests to the U.S. EPA will be considered on a case-by-case basis
under the provisions contained in Section 2.8 (Modifications of Methods by Users)
of Appendix C to 40 CFR Part 58. When granted, such approvals will limit use of the
low temperature operation to periods during the wintertime months, when outdoor
temperatures exceed 25° C no more than 5 percent of the time, and to monitoring
locations where the prevailing ambient PM-10 aerosol has, or is expected to have, a
significant contribution from volatile or semi-volatile components. The recommend-
ed set points for operation of the TEOM Series 1400 and 1400a PM-10 monitors at
the lower temperature are as follows:

Enclosure Temperature (if applicable): 25° C

Case Temperature: 30° C
Air Temperature: 30° C
Cap Temperature: 0° C (off)

A packet is available from R&P to assist agencies in applying for this user
modification.

U.S. EPA Designation (continued)

EPA

On March 3, 1994 the U.S. EPA approved the operation of the Series 1400 and 1400a
monitors at alternate main flow rates of 1 and 2 l/min in addition to the standard setting
of 3 l/min. The following main and auxiliary flow rates apply to the approved flow rate
settings:

3 l/min Main Flow 13.67 l/min Aux Flow No change to Flow Splitter
2 l/min Main Flow 14.67 l/min Aux Flow Use 2 l/min Adapter (36-001664)
1 l/min Main Flow 15.67 l/min Aux Flow Use 1 l/min Adapter (57-001297)

When operating the instrument at the lower alternate flow settings, replace references
to the 3 l/min main flow and 13.67 l/min auxiliary flow with the actual flow rates used.

On October 24, 1995 the U.S. EPA approved the modification of the Series 1400a
monitor to include new features in units with serial numbers containing the “AB”
designation. These changes include, but are not limited to, the redesign of the mass
transducer, new layout of the control unit, inclusion of sensors for ambient tempera-
ture and pressure, and the use of mass flow controllers designed by Rupprecht &
Patashnick Co., Inc.

This instrumentation from Rupprecht & Patashnick Co., Inc. (R&P) is covered by one

Section 1: Introduction

The TEOM Series 1400a Ambient Particulate Monitor has received the following
major regulatory recognitions:

• U.S. EPA PM-10 equivalency approval EQPM-1090-079

• PM 2.5 measurements within the context of a U.S. EPA correlated accept-
able continuous monitor (40 CFR 58)
• European Union PM-10 recognition within the context of European Norm
EN 12341
• German EPA approval as an equivalent TSP monitor.

The Series 1400a Monitor (Figure 1-1) incorporates the patented Tapered Element
Oscillating Microbalance (TEOM) technology developed by Rupprecht & Patashnick
Co., Inc. to measure particulate matter mass concentrations continuously. The Series
1400a Monitor can be configured with a variety of sample inlets to measure PM-10,
PM-2.5, PM-1 or TSP concentrations. The microprocessor-based unit accommodates
all siting requirements and provides internal data storage and analog and serial data
input/output capabilities.

Filter-based, direct mass measurements are considered the standard technique for
determining particulate matter mass concentration. TEOM instruments from R&P are
the only filter-based systems with real-time data output and real-time mass measure-
ment capability. The exchangeable filter in the Series 1400a Monitor also can be used
to determine heavy metal concentrations using standard analytical laboratory meth-
ods.

1.1. ADVANCED FEATURES

On October 24, 1995 the U.S. EPA approved the modification of the Series 1400a
Monitor to include new features in units with serial numbers containing the “AB”
designation. These changes include, but are not limited to, the redesign of the mass
transducer, new layout of the control unit, inclusion of sensors for ambient tempera-
ture and pressure, and the use of mass flow controllers designed by R&P.

The Series 1400a Monitor contains the following features:

• New mass transducer design provides improved mass resolution for

short-term measurements.

• Instrument operation at 1, 2 or 3 l/min to provide time-resolved mass

measurements in locations ranging from clean-background monitoring
stations to highly polluted urban areas.

• Incorporates R&P’s “AB” technology for enhanced measurement stabil-

ity for mobile installations

• Filter-based, direct mass monitoring using R&P’s patented TEOM

technology that never requires mass recalibration. The instrumentation
contains no radioactive components and has a 2-year warranty.

• Continuous dust monitor with U.S. EPA approval (EQPM-1090-079)

that complies with the California ARB 1-hour acceptance criteria for
mass concentration precision. TEOM instrumentation has German TÜV
approval for TSP measurements.

• Mass and time resolution (mass transducer minimum detection limit of

0.01 µg). The instrument has a precision of ±5.0 µg/m3 for 10-minute
averaged data and ±1.5 µg/m³ for 1-hour averages.

• The active volumetric flow control system maintains a constant volumet-

ric flow at the flow rate specified by the user by incorporating ambient
pressure and temperature sensors.

• Available with a choice of sample inlets for PM-10, PM-2.5, PM-1 or

TSP measurements

• Sample filters can be analyzed after exposure for heavy metals using
standard laboratory techniques such as AA or ICAP.

1.3. APPLICATION RANGE OF THE SERIES 1400A MONITOR

The Series 1400a Monitor is a real-time device used for measuring the particulate
matter mass concentration of particulate matter smaller than 10 µm diameter in
outdoor and indoor ambient air, as well as for other particle size cut-points.

TEOM instruments are the only filter-based mass monitors that measure the mass of
particulate matter suspended in gas streams in real time. This is made possible through
the use of an inertial mass transducer patented in the U.S. and internationally by
Rupprecht & Patashnick Co., Inc.

The monitor is ideally suited for applications demanding real-time ambient air
particulate matter monitoring in outdoor, indoor or industrial settings. In its most
common configuration, it calculates mass concentration, mass rate and the total mass
accumulation on the TEOM filter cartridge under the following conditions:

Flow rate through sample inlet 16.7 l/min (1 m3/hr)

Main flow rate 3 l/min
Temperature of sample stream 50º C
Particulate matter concentration less than 5 µg/m3 to several g/m3

NOTE: The temperature of the sampled air may vary be-

tween -40 and 60 C. The sensor and control units must be
weather-protected within the range of 2 to 40 C. The user
may purchase a Complete Outdoor Enclosure (Appendix K)
that will hold the sensor unit, control unit and pump. The
enclosure also has room in its rack for a data logger, modem
or other appropriately sized equipment.

The ambient temperature sensor can measure temperatures ranging from -25º to 105º
C, with an accuracy of ±2º C. The ambient pressure sensor is rated from 0.68 to 1.09
atm, and is specified to have a maximum eroor of 1.5% in the temperature range of
0º to 85º C. The Series 1400a Monitor smooths both the average temperature and
average pressure over a period of approximately 15 seconds.

The Series 1400a Monitor uses the PM-10 inlet to perform a 10 µm particle size cutoff.
When fitted with a total suspended particulate (TSP) inlet deigned for 1 m3/h operation
instead of the PM-10 inlet, the instrument functions as a TSP monitor. Other size-
selective inlets are available from R&P for PM-2.5 and PM-1 monitoring (Section 2).

1.4. GENERAL SYSTEM CONFIGURATION

The Series 1400a Monitor is composed of two major components: the TEOM sensor
unit and TEOM control unit (Figure 1-1). The system’s sample inlet and flow splitting
hardware are not shown in this figure. The user enters the system parameters into the
control unit with the keypad located on the front of the unit. Additionally, the system
is furnished with software for personal computers (PCs) to allow the user to view the
operation of the instrument in real time, and to allow the user to enter system values
directly from the PC. The instrument does not require a dedicated computer to
function in the field.

The sensor unit contains the mass measurement hardware that continuously monitors
the accumulated mass on the system’s exchangeable filter cartridge. By maintaining
a flow rate of 3 l/min through the instrument and measuring the total mass accumu-
lated on the filter cartridge, the device can calculate the mass concentration of the
sample stream in real time.

The control unit houses an industrially hardened microprocessor system, flow control
hardware, a gauge to determine filter lifetime, transformers and power supplies. This
part of the monitor can be mounted on a 19-inch rack for convenient installation.

1.5. THEORY OF OPERATION

The Series 1400a Monitor is a true “gravimetric” instrument that draws ambient air
through a filter at a constant flow rate, continuously weighing the filter and calculating
near real-time (10 minute) mass concentrations. In addition, the instrument computes
the total mass accumulation on the collection filter, as well as 30-minute, 1-hour, 8-
hour and 24-hour averages of the mass concentration. The use of a hydrophobic filter
material, along with sample collection at above-ambient temperature (50° C), reduces
the necessity for humidity equilibration. Both analog and RS232 outputs are available
to transmit the measurements to a user’s data acquisition system. The instrument’s
internal storage buffer can store a large amount of data for later viewing on the
instrument’s display or downloading over the RS232 output.

When the instrument samples, the ambient sample stream first passes through the
PM-10 inlet (Figure 1-2). At its design flow rate of 16.7 l/min, this inlet allows
particles smaller than 10 µm diameter to pass through. At the exit of the PM-10 inlet,
the 16.7 l/min flow is isokinetically split into a 3 l/min sample stream that is sent to
the instrument’s mass transducer and a 13.7 l/min exhaust stream.

Inside the mass transducer, this sample air stream passes through a filter made of
Teflon-coated borosilicate glass fiber. This filter is weighed every two seconds. The
difference between the filter’s current weight and the filter’s initial weight (as
automatically measured by the instrument after the installation of the filter) gives the
total mass of the collected particulate matter. These instantaneous readings of total
mass are then smoothed exponentially (using a selectable time constant) to reduce
noise.

Next, the mass rate is calculated by taking the change in the smoothed total mass
between the current reading and the immediately preceding one and expressing this
as a mass rate in g/sec. This mass rate is also smoothed exponentially to reduce noise.
Finally, the mass concentration in µg/m3 is computed by dividing the mass rate by the
flow rate (corrected to EPA standard temperature and pressure and expressed in m3/
sec), and then multiplying the result by 106 to convert from g/m3 to µg/m3.

Internal temperatures in the instrument are controlled to minimize the effects of

changing ambient conditions. The sample stream is preheated to 50° C before entering
the mass transducer so that the sample filter always collects under conditions of very
low (and therefore, relatively constant) humidity. All measurement and temperature
functions of the instrument are controlled by a dedicated microcontroller. This
computer has both digital and analog capability for multipurpose interfacing with
external data collection systems. The instrument’s rack-mountable control unit has a
scrollable four-line display that shows the current values of computed data.

1.5.1. THE FLOW SYSTEM

Figure 1-2 shows the flow of the sample stream through the Series 1400a Monitor. The
particle size separation at 10 µm diameter takes place as the sample proceeds through
the PM-10 inlet. The flow splitter separates the total flow (16.7 l/min) into two parts:
a main flow of 3 l/min that enters the sensor unit through the sample tube, and the
auxiliary (bypass) flow of 13.7 l/min. The main flow passes through the exchangeable
filter in the mass transducer (Figure 1-3), and then proceeds through an air tube and
in-line filter to a mass flow controller. The bypass flow is filtered in the large bypass
in-line filter before it enters a second mass flow controller. A single pump provides
the vacuum necessary to draw the sample stream through the system.

1.5.2. MASS TRANSDUCER OPERATION

The weighing principle used in the TEOM mass transducer is similar to that of a
laboratory microbalance in that the mass detected by the sensor is the result of the
measurement of a change in a parameter (in this case, frequency) that is directly
coupled via a physical law (or from first principles).

The tapered element at the heart of the mass detection system (Figure 1-3) is a hollow
tube, clamped on one end and free to oscillate at the other. An exchangeable filter
cartridge is placed over the tip of the free end. The sample stream is drawn through
this filter, and then down the tapered element. This flow is maintained at a constant
volume by a mass flow controller that is corrected for local temperature and
barometric pressure.

The tapered element oscillates precisely at its natural frequency, much like the tine
of a tuning fork. An electronic control circuit senses this oscillation and, through
positive feedback, adds sufficient energy to the system to overcome losses. An
automatic gain control circuit maintains the oscillation at a constant amplitude. A
precision electronic counter measures the oscillation frequency with a 2-second
sampling period.

The tapered element is, in essence, a hollow cantilever beam with an associated spring
rate and mass. As in any spring-mass system, if additional mass is added, the
frequency of the oscillation decreases. This can be seen by observing the frequency
on the four-line display of the TEOM control unit (Section 8), and operating the Series
1400a Monitor both with and without a filter in place.

In a spring-mass system the frequency follows the equation:

f = (K / M)0.5 (1)

where:

f = frequency (radians/sec)
K = spring rate
M = mass

K and M are in consistent units. The relationship between mass and change in
frequency can be expressed as:

1 1
dm = K0 –––––– - –––––– (2)
f12 f02

SECTION 1: INTRODUCTION PAGE 1-13

 Revision B.001

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

where:

dm = change in mass
K0 = spring constant (including mass conversions)
f0 = initial frequency (Hz)
f1 = final frequency (Hz)

When this equation is rearranged, you can solve for the spring constant, K0:

dm
✔ The instrument com- K0 = ––––––––––––––– (3)
putes a baseline frequency 1 1
before computing mass –––––– - ––––––
concentration results.
f 12 f 02

Thus, K0 (the calibration constant for the instrument) can be easily determined by
measuring the frequencies with and without a known mass (pre-weighed filter
cartridge).

In actual operation, the Series 1400a Monitor always measures the entire mass of the
system using the equation:

M = K 0 / f2 (4)

At the end of the instrument’s 30 minute flow and temperature equilibration period,
the monitor averages the frequency for a short period and uses this frequency to
compute the baseline mass. Until the next time the unit is reset or taken out of its data
collection mode, the frequency is sampled every two seconds and the system mass is
calculated.

The difference between this mass and the baseline mass is the mass change of
particulate matter collected on the filter cartridge.

1.5.3. MASS COMPUTATION M ETHODOLOGY

The calculation of the total mass accumulation on the filter, mass rate and mass
concentration are discussed in this section. All of the formulas assume consistent
units. In the operating software, unit conversions are made as required.

Several variables are used by the system software to compute mass data:

Gate_Time = 2 The sampling period (seconds) for each individual

frequency measurement.

TM Ave = 300 The effective time (seconds) over which frequency

data points are smoothed to compute total mass.
Smoothing is done exponentially, and this value
represents the time required for 86% of a step
change in the raw total mass to be reflected in the
smoothed total mass output; i.e., 2 time constants.

Even if the TM Ave is changed by the user to an

✔ Each TEOM instrument averaging time that is different from 300 seconds,
has a unique calibration the 30-minute, 1-hour, 8-hour and 24-hour mass
constant, K0. concentration averages are all computed based upon
a TM Ave of 300 seconds that is calculated inter-
nally by the instrument.

MR_MC Ave = 300 The effective time (seconds) over which the differ-
entials between successive total mass data points
are smoothed to compute mass rate and mass con-
centration. The exponential smoothing function used
to compute smoothed mass rate_mass concentra-
tion is identical to that of the total mass.

K0 = calibration The calibration constant of the system’s mass

constant transducer is determined by R&P before the instru-
ment is shipped to the user. This constant is unique
for every TEOM system and is based upon the
physical characteristics of the tapered element.

2 × Gate_Time
MR_MCAlpha = ––––––––––– A constant used in the mass rate_mass
MR_MC Ave concentration smoothing routine.

After the Series 1400a Monitor is turned on or reset by pressing the <F1> or <Run>
key on the control unit, the system software determines whether set point tempera-
tures are within acceptable tolerance ranges (Section 6). If the temperatures and flow
rates are not within these ranges, the instrument waits until all temperatures and flow
rates have remained within these limits for 30 minutes before starting data collection.
The monitor is in Operating Mode 1 during this stabilization period.

Once this stabilization period ends, the Series 1400a Monitor enters Operating Mode
2, and computes the system mass of the mass transducer (Masso). This is equal to the
summation of the effective mass of the tapered element, the mass of the filter, and the
mass of any particulate matter collected on the filter. This computation is performed
by averaging the tapered element frequency over ten 2-second periods (Gate_Time),
and then employing the following formula derived in equation 4:

Masso = K0 / f02 (5)

where:

Masso = the baseline mass of the mass transducer (tare weight of filter
and tapered element)

K0 = the calibration constant of the mass transducer

f0 = the average tapered element frequency during the initial ten 2-

second periods

After the instrument has sampled the tapered element frequency for these ten 2-second
periods, it begins computing a new system total mass value (Massi) every 2 seconds
using equation 4. With these Masso and Massi values, the system then computes a new
particulate matter total mass value (TMi) every 2 seconds.

TMi = Massi - Mass o (6)

To provide data smoothing, an exponential smoothing routine is applied to these TMi

values to compute a new smoothed total mass value every 2 seconds.

SmoothTMi = TMAlpha × TMi + (1 - TMAlpha) × SmoothTMi-1 (7)

SECTION 1: INTRODUCTION PAGE 1-16

 Revision B.001

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

At the same time that the instrument computes these SmoothTMi values, it also
calculates the incremental change in sample mass between successive smoothed
readings according to the following formula:

Delta_Massi = SmoothTMi - SmoothTMi-1 (8)

These incremental mass changes are smoothed according to the following formula,
where MR stands for mass rate:

SmoothMRi = MR_MCAlpha × Delta_Massi + (1 - MR_MCAlpha) × SmoothMRi-1 (9)

These smoothed mass rate readings are converted to mass concentration data using the
following formula:

SmoothMRi
SmoothMCi = ––––––––––– × 106 (10)
Flow_RateEPA

where:

Flow_RateEPA = 3.0 l/min volumetric flow rate set point, converted to

EPA standard temperature and pressure

Once the SmoothTMi values have been computed for 150 seconds (TM Ave / 2), the
instrument enters Operating Mode 3. At this point, the smoothed total mass data
(SmoothTMi) are shown on the monitor’s four-line display and are transmitted to the
monitor’s analog and RS232 connectors. Prior to this time, the total mass indicated
by the instrument is equal to 0.

After the SmoothMCi values have been calculated for 300 seconds (TM Ave / 2 +
MR_MC Ave / 2), the monitor enters Operating Mode 4. At this point, the smoothed
mass concentration data (SmoothMCi) are shown on the monitor’s four-line display
and are transmitted to the monitor’s analog and RS232 connectors. Previous to this
time, the mass concentration indicated by the instrument is equal to 0.

The 30-minute, 1-hour, 8-hour and 24-hour mass concentration averages are com-
puted differently from the “instantaneous” mass concentrations. This notwithstanding,
the averaged results of the instantaneous readings are identical to these longer-term
averages except for a very slight time offset caused by the additional exponential
smoothing performed on the short-term data. Because the longer-term averages are
all computed in the same manner, only one example is given below.

The 1-hour mass concentration average (01-Hr MC) is computed by recording the
smoothed total mass (SmoothTMi, internal TM Ave = 300 sec) every hour on the hour,

SECTION 1: INTRODUCTION PAGE 1-17

 Revision B.001

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

and performing the following calculation:

SmoothTM hour - SmoothTM hour-1

01MC = –––––––––––––––––––––––––– × 106 (11)
Total_FlowEPA

where:

SmoothTMhour-1 = Smoothed total mass at the beginning of the

averaging period, internal TM Ave = 300 sec

SmoothTMhour = Smoothed total mass at the end of the averaging

period, internal TM Ave = 300 sec

Total_FlowEPA = Total volumetric flow in m3 for the averaging

period (based upon flow rate setpoint), con-
verted to EPA standard temperature and pressure

The instrument updates the longer-term mass concentration averages at the following
times:
30-minute average (30MC) every half hour on the half hour
1-hour average (01MC) every hour on the hour
8-hour average (08MC) every hour on the hour
24-hour average (24MC) every hour on the hour

After the instrument has been turned on or reset, these longer-term averages are equal
to 0 until a complete period’s data has been collected.

Sampling is performed by the Series 1400a Monitor using a variable mass flow rate
that maintains a constant volumetric flow rate appropriate to the PM-10 sampling
inlet. Because this flow rate is controlled by mass flow controllers (MFCs), the mass
flow rate must be adjusted for temperature and pressure to maintain the appropriate
volumetric flow rates within acceptable limits.

The mass flow controllers (MFCs) in the Series 1400a Monitor are internally
calibrated for a standard temperature and pressure of 0° C and 1 Atmosphere (1013.2
millibars or 760 mm Hg). The user must enter the seasonal average temperature (Ave.
Temp.) and average barometric pressure (Ave. Pres.) at the measurement site to allow
the instrument to sample at the correct volumetric flow rate (Section 6).

Alternately, the user can set up the instrument to automatically measure the ambient
temperature and pressure using hardware supplied with the unit. The microprocessor
calculates the correct mass flow set point (Flow_RateSTP) with this information using
the following formula:

SECTION 1: INTRODUCTION PAGE 1-18

 Revision B.001

273.15 Ave. Pres.

Flow_RateSTP = Flow_RateVol × –––––––––––––––– × ––––––––– (12)
Ave. Temp. + 273.15 1.0
where:

Flow_RateSTP = Control set point to mass flow controller (equivalent flow

at 0° C and 1 Atmosphere)

Flow_RateVol = Volumetric flow rate set point (l/min) to be 3.0 l/min for
the sample (main) flow and 13.67 l/min for the auxiliary
flow (Section 6)

Ave. Temp. = Seasonal average temperature entered by the user (°C)

Ave. Pres. = Seasonal average barometric pressure entered by the user

(Atmospheres, where 1 Atmosphere = 1013.2 millibars or
760 mm Hg)

NOTE: When using actual conditions for active volumetric

flow control, substitute the actual (local) temperature and
pressure for the average temperature and pressure variables
in equation 12.

PM-10 mass concentration data reported to the U.S. EPA must be referenced to
standard cubic meters of air based on a standard temperature and pressure of 25° C
and 1 Atmosphere (atm), respectively. For the instrument to report mass concentra-
tions according to this EPA standard, the user must ensure that the standard
temperature (Std. Temp.) and standard pressure (Std. Pres.) entered in the instrument
equal 25° C and 1 Atmosphere (Section 6). These are the default values for the
instrument.

The flow rates referenced internally by the instrument to 0° C are converted to EPA
standard conditions using the following computation:

Std. Temp. + 273.15 1 atm

Flow_RateEPA = Flow_RateSTP × ––––––––––––––––– × –––––––– (13)
273.15 Std. Pres.

This Flow_RateEPA is used to determine the mass concentration reported by the

instrument, as shown in equation 10.

The Total_FlowEPA referenced in equation 11 for computing longer-term mass

SECTION 1: INTRODUCTION PAGE 1-19

 Revision B.001

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

concentration averages is obtained by summing the Flow_RateEPA over the period of

the longer-term average. For example, the 1-hour Total_FlowEPA is obtained by:

Total_FlowEPA (m3) = Flow_RateEPA (l/min) × period (minutes) × 1/1000 (l/m3) (14)

NOTE: When reporting concentrations to actual conditions,

the values for standard and average temperatures must be set
to “99,” and the standard and average pressures must be set
to “9,” when in the Set Temps/Flows screen (Section 6). This
will ensure that the monitor uses the current actual values for
temperature and pressure in equation 13.

Section 2: Hardware Setup

To install the Series 1400a Monitor and set up the system, you must check the voltage
setting of the control unit (Section 2.3.1); assemble the sensor flow connections
(Section 2.3.2.1), bypass flow connections (Section 2.3.2.2), pump connections
(Section 2.3.2.3), sensor unit connections (Section 2.3.4), flow splitter (Section
2.4.1), tripod (Section 2.4.2), sampling system components (Section 2.4.3) and the
sample tube (Section 2.4.4); and install a sample inlet onto the flow splitter (Section
2.4.5.1). After you have set up the system, you must perform a leak check on the
monitor (Section 3.4) and install a TEOM filter (Section 3.1.1) in the mass transducer
before starting a sample run.

If you want to mount the control unit in a rack (Section 2.3.3), you must install the
control unit into the rack directly after you assemble the pump connections (Section
2.3.2.3). If you want to install the monitor in an outdoor location, refer to Appendix
K for further instructions. Consult R&P for specific site recommendations.

2.1. INSTALLATION CONSIDERATIONS

The Series 1400a Monitor consists of two basic components: the sensor unit
(containing the sample inlet and mass transducer) and the control unit (containing the
operator terminal and control electronics). The two units are connected by a 10-meter
(optionally 2 or 20 m) cable/tube assembly.

The control unit is suitable for standard rack mounting and may be located in any
convenient indoor location which is maintained between 2° and 40° C (35° to 104° F).
✔ The instrument must be
located in a weather- R&P strongly recommends that the sensor unit of the Series 1400a Monitor also be
protected environment. installed in an indoor or weather-protected location. If the sensor unit is installed in
an indoor location, the user must run a sampling tube through the roof of the
monitoring site (Section 2.4).

Although the TEOM monitor is inherently rugged, it is a precision instrument. The

user will obtain the best operating conditions and longest instrument life when the unit
is not exposed to extremes of weather. Filter exchange, in particular, may be best
accomplished by a technician operating in an indoor environment where there is no
possibility of rain or snow contaminating the filter.
✘ Be sure to install the
ambient temperature Be sure to install the ambient temperature sensor (Section 2.4.3). If you do not install
sensor. the ambient temperature sensor, and then you set the average temperature to “99” and
the average pressure to “9” (Section 6), the mass flow controller will attempt to control
the sample flow as if the ambient temperature is absolute zero.

Appendix K for further instructions. Consult R&P for specific site recommendations.

To achieve the best results, locate the TEOM sensor unit in an environment with
relatively slow temperature fluctuations. Avoid sampling locations with direct
exposure to sunlight or that are in close proximity to a heating or air-conditioning
outlet. To avoid condensation in the sample tubing, R&P strongly recommends that
the user insulate the sample tube extensions with pipe insulation when operating the
instrument in areas of high humidity.

2.4.3) and sample tube assembly (Section 2.4.4), and then choose an appropriate inlet
(Section 2.4.5).

2.4.1. FLOW SPLITTER ASSEMBLY

An isokinetic flow splitter (Figures 2-37 and 2-38) is used in combination with a
second automatic flow controller to divide the sample flow into two components after
the air stream passes through the size-selective inlet. The two sample flow
components are the main flow (3 l/min) that flows to the TEOM mass transducer, and
the auxiliary (or bypass) flow (13.67 l/min) that is maintained by the second flow
controller. The flow splitter should be located directly below the sample inlet (Figure
2-1). Optional flow adapters allow system operation at a 1 or 2 l/min main flow rate
in areas with elevated particulate matter concentration. Units equipped with a 1 or 2
l/min flow adapter operate at main flow rate of 1 or 2 l/min and auxiliary flow rate of
15.67 or 14.67 l/min, respectively.

If a 2 l/min flow adapter is installed in the Series 1400a system, replace all references
in this manual to a 3 l/min main flow with 2 l/min, and all references to a 13.67 l/min
auxiliary flow with 14.67 l/min. Likewise, for monitors equipped with the 1 l/min flow
adapter, replace all references in this manual to a 3 l/min main flow with 1 l/min, and
all references to a 13.67 l/min flow with 15.67 l/min.

2.4.5. INLET SELECTION

The Series 1400a Monitor can be configured with a variety of inlet systems. This
appendix describes the procedures for installing a sample inlet onto the sampling
system setup (Section 2.4.5.1), and converting the Series 1400a Monitor from a PM-
10 to a PM-1 monitor (Section 2.4.5.2), a PM-2.5 monitor (Section 2.4.5.3), or a total
suspended particulate (TSP) monitor (Section 2.4.5.4). It also includes a statement
regarding the TEOM monitor adjustment factor (Section 2.4.5.5).

NOTE: If your Series 1400a Monitor is configured for use as

a PM-10 or PM-2.5 monitor with the original PM-10 inlet
(Figure 2-71) and you are experiencing difficulties with rain
intrusion, you can purchase the modified PM-10 inlet (Fig-
ure 2-72) from R&P (57-004742). This inlet substantially
reduces the possibility of rain intrusion, and is installed in
the same manner as the PM-10 inlet. Also, you can convert
the original PM-10 inlet to a modified PM-10 inlet by using
the PM-10 Inlet Conversion Kit (55-004747). Conversion
instructions are included with the kit.

2.4.5.5. TEOM MONITOR ADJUSTMENT FACTORS

The following statement refers to the variables designated “Const A” and “Const B”
on the Set Hardware screen (Figure 2-81) of the Series 1400a Monitor.

Figure 2-81. Set Hardware

screen. SET HARDWARE
Const A> 3.000
Const B 1.030
Soft Rate 0.000000

This statement also can be found on R&P’s website (www.rpco.com) under the
Frequently Asked Questions (FAQ) area for the Series 1400a Monitor. Any new
information regarding this issue also will be included in this area of the website.

To make an informed decision as to the choice of the TEOM monitor adjustment

factors, it is important to understand the origin of the adjustment factors. The TEOM
monitor makes a minor, empirically established adjustment to the mass concentra-
tion. This accounts for moisture equilibration differences reflected in the choice of
filter media and equilibration thermodynamics used in manual and automated
methodologies. This is done using the formula Y=A+Bx, where Y is the adjusted mass
concentration, x is the unadjusted mass concentration, A (Const A) is the intercept
factor and B (Const B) is the slope factor. The values of A and B must be set to their
default values of 3.000 and 1.030, respectively, for the Series 1400a Monitor to be
used as a U.S. EPA equivalent method for PM-10 measurements. These adjustment
factors were determined at sites where nonvolatile particulate matter dominated and,
therefore, the adjustment factors reflect the filter character more than they reflect the
particulate matter.

For PM-2.5 measurements, it is justifiable to use the original constants (3.000 and
1.030), because the technical rationale may still apply. The other option is to use no
adjustment for PM-2.5, by setting the constants to values of 0.000 (Const A) and 1.000
(Const B). In either case, the adjustment factors used may be revisited later as more
information becomes available on the best approach. Because the adjustment is
attained by a simple linear transformation, it is possible to recalculate the mass
concentration values later based upon new information.

2.5. HOUSING THE INSTRUMENT OUTDOORS

The instrument can be located outside of an air monitoring station if sufficient

protection is provided from adverse weather conditions and enough ventilation is
supplied to ensure cooling in the summer. An optional heated and air-conditioned
Complete Outdoor Enclosure is available for housing the sensor unit, control unit and
pump (Figure 2-82). The enclosure has room in its rack for a data logger, modem or
other appropriately sized equipment.

The foundation for the outdoor enclosure should be sturdy. If the user wants to mount
it on a roof, the support structure of the enclosure must be attached directly to the roof,
rather than to auxiliary walkways or platforms. Contact R&P to purchase an enclosure
and refer to Appendix K for instructions on setting up the Complete Outdoor
Enclosure.

3.2. FILTER L OADING

The filter loading percentage value indicates the fraction of the TEOM filter’s total
capacity that has been used. You can check the filter loading percentage on the
monitor’s Main screen (Figure 3-25). Because this value is determined by the pressure
drop of the main sample flow line, the instrument always shows a non-zero value even
if no filter is mounted in the mass transducer. New filters generally exhibit filter
loading percentages of 15% to 30% at a main flow rate of 3 l/min, and less at lower
flow rates.

Filter loading percentage

with filter loading percent- OK 4+ 11% NU 09:39
age highlighted. Mass Conc> 33.6
30-Min MC 26.8
01-Hr MC 12.5

TEOM filters must be replaced before the filter loading percentage reaches 100% to
ensure the validity of the data generated by the instrument (Figure 3-26). At some
point above 100%, the main flow drops below its setpoint.

Status condition Filter loading percentage

ment is required. Mass Conc> 33.6
30-Min MC 26.8
01-Hr MC 12.5

If the filter loading percentage is higher than 30% (at a main flow rate of 3 l/min) when
a new TEOM filter is placed on the mass transducer, or if the lifetime of consecutive
TEOM filters becomes noticeably shorter, you may need to replace the in-line filter
in the main flow line (Section 12).

Testing performed for official U.S. EPA PM-10 measurements must be conducted
with TEOM filters (Section 2.2) made of Teflon-coated, glass-fiber filter paper.
Filters should be stored inside the sensor unit for easy access and to keep them dry and
warm (Section 3.1.3).

SECTION 3: SAMPLE PREPARATION PAGE 3-17

 Revision B.002

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

3.2.1. FILTER LIFE

Filter life depends upon the nature and concentration of the particulate matter
sampled, as well as the main flow rate setting. TEOM filters must be replaced when
the filter loading value approaches 100%. This generally corresponds to a total mass
accumulation on the filter of approximately 3-5 mg. Filter life at a main flow rate of
3 l/min is generally 21 days at an average PM-10 concentration of 50 µg/m3. Filter life
is longer at lower flow rates because the particulate matter accumulation on the filter
is slower. Flow splitter adapters (Section 2) for 1 l/min and 2 l/min operation can be
used in areas with elevated particulate matter concentrations or where a longer filter
life is required.

3.2.2. WHEN TO REPLACE TEOM F ILTERS

TEOM filters must be replaced before the filter loading percentage on the status line
of the Main screen reaches 100%. When the filter loading percentage is greater than
90%, the “CHECK STATUS” light (located below the “POWER” button on the front
of the TEOM control unit) (Figure 3-27) lights up and the status condition code
(Section 7) on the status line of the Main screen changes from “OK” to “X” (Figure
3-26).

Figure 3-27. Control unit

with the “CHECK STATUS”
light (A) highlighted.

If you operate your unit at a main flow rate of less than 3 l/min, your instrument’s filter
loading percentage may not reach 90% on the Main screen even though the filter is
loaded beyond 90%. In this case, the user should replace the TEOM filter every 14-
21 days to avoid exceeding the filter’s maximum capacity.

3) Plug the pump (Figure 3-17) into an appropriate power source to

draw a sample stream through the system.

Once the power switch is pressed, the “CHECK STATUS” light (Figure 3-27) will
light because the flow rates and temperatures are outside of tolerance ranges. The
“CHECK STATUS” light will remain lit during the first 30 minutes after the power
switch is pressed while the monitor warms up. The status light automatically turns off
after all flow rates and temperatures reach tolerance ranges (Section 4.3.1.2).

The flow controllers inside the control unit make a slight “clicking” sound when the
instrument is turned on. The instrument automatically resets itself when it is turned
on. As part of this initialization procedure, the monitor waits until the flow rates and
temperatures stabilize within a narrow range (Section 6) for 30 minutes before starting
data collection. This ensures the validity of all data points computed by the system.

9) When in the Main screen, the main flow reading should read less
than 0.15 l/min and the auxiliary flow reading should read less
than 0.60 l/min. If the main flow reading is less than 0.15 l/min
and the auxiliary flow reading is less than 0.65 l/min

18
18.. If the main flow reading is greater than 0.15 l/min and the
auxiliary flow reading is greater than 0.65 l/min
l/min,, you must repeat
the leak check procedure using an offset value to account for the
characteristic non-linearity of the mass flow sensor for flow
values near 0 l/min. Go to step 12.
12) To determine the non-linearity offset value (NOV), slowly open the
valve located on the flow audit adapter (Figure 3-33) and discon-
nect or unplug the vacuum pump.
IMPORTANT: Be sure to open the valve on the adapter slowly to gradually
release the vacuum in the system.
13) Wait 1 minute and observe the main flow and auxiliary flow
readings. These are the NOVs for both the main flow and
auxiliary flow. Record these values.
14) Plug in or reconnect the vacuum pump, and wait 3-5 minutes to
allow the main flow and auxiliary flow to stabilize.
15) When both flow rates have stabilized, close the valve on the flow
audit adapter (Figure 3-34)
3-34)..
16) When in the Main screen, the main flow reading should read less
than 0.15 l/min plus the main flow NOV, and the auxiliary flow
reading should read less than 0.60 l/min plus the auxiliary flow
NOV. For example, if the NOV for the main flow was recorded as
0.08 l/min, add 0.08 to 0.15 for a total of 0.23 (0.08 + 0.15 = 0.23).
The main flow reading should be less than 0.23 l/min. If the NOV
for the auxiliary flow was recorded as 0.12 l/min, add 0.12 to 0.65
for a total of 0.77 (0.12 + 0.60 = 0.77). The auxiliary flow reading
should be less than 0.77 l/min.
17) If the flow readings exceed these calculated values (the NOVs
plus 0.15 l/min for the main flow and 0.65 for the auxiliary flow),
perform an analog board calibration and mass flow controller
calibration (refer to service manual). This also may indicate that
there is a faulty connection or component (such as the mass flow
controller or the vacuum pump) in the system. If the flow read-
ings do not exceed these calculated values, go to step 18.
18) Slowly open the valve located on the flow audit adapter.
IMPORTANT: Before removing the flow audit adapter, open the valve on the
adapter slowly to gradually release the vacuum in the system.
19) Remove the flow audit adapter from the flow splitter.

4.2.1. STATUS LINE

The status line (Figures 4-3 and 4-4) of the Main screen provides a summary of the
current operational conditions of the instrument.

The status line contains the following information:

OK This field contains the current status condition. It is

an alphanumeric code that summarizes the opera-
tional status of the instrument, indicating whether
any status condition exists. Refer to Section 7 for an
explanation of the unit’s status codes.

4 This field contains the unit’s current operating mode.

It indicates the instrument’s current operational
setting and the type of data being computed by the
monitor. The operating modes are:

•1 Operating Mode 1: Mass values are not

currently being computed because temper-
atures and flow rates are stabilizing. The
temperatures and flow rates must remain
within a very narrow range of values (Sec-
tion 5) for 30 minutes before the instrument
enters Operating Mode 2. The monitor al-
ways starts in Operating Mode 1 when it is
turned on or reset. Press the <F1> or <RUN>
key to reset the instrument from any oper-
ating mode. This action always causes the
instrument to enter Operating Mode 1.

•2 Operating Mode 2: Data collection has be-

gun, but the first total mass value has not yet
been computed.

•3 Operating Mode 3: The first total mass

value has been computed, but mass concen-
tration and mass rate are not yet available.

•4 Operating Mode 4: The unit is fully opera-

tional in Operating Mode 4 and normally
resides in this mode. All mass values are
being computed.

SECTION 4: SOFTWARE OVERVIEW PAGE 4-3

 Revision B.002

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

•S Setup Mode: When the unit is in this oper-

ating mode, it continues to draw a sample
flow and maintain operational temperatures
but it does not collect any data. Certain
operating parameters such as temperatures
and flow rates can only be changed in this
mode, because doing so during data collec-
tion (Operating Modes 1-4) would affect the
data. Press the <DATA STOP> key to enter
the Setup Mode while in any operating mode.
When the unit is in the Setup Mode (S), the
user can change all of the system’s param-
eters. To leave the Setup Mode and start data
collection, press either the <F1> or <RUN>
key to return the monitor to Operating Mode
1. If the instrument remains in the Setup
Mode for 5 minutes without the user press-
ing any key on the keypad, the monitor will
automatically return to Operating Mode 1.

•X Stop All Mode: When the unit is in this

operating mode, it suspends operation of
the instrument. In this mode, data collec-
tion ceases, flow rates in the system drop to
zero, and the output to the temperature
circuits is turned off. This is an “emergency
state” that is activated by pressing the
<STOP ALL> key on the instrument’s key-
pad. To leave this mode, press either the
<F1> or <RUN> key to enter Operating
Mode 1, or the <DATA STOP> key to enter
the Setup Mode.

+ This field contains the status of analog output chan-

nel 1 (A/O 1). If the “A/O 1” field of the Main screen
status line is blank, analog output 1 is operating in its
usual fashion (Section 9). If the A/O 1 field contains
a “+”, analog output 1 is being used as a status watch
indicator. When defined in this fashion, analog
output 1 transmits a full scale signal (for example,
10 VDC if the channel is configured for 10 VDC
operation) if a status condition exists in the temper-
atures, flows or oscillation of the mass transducer. If
no such status condition exists, analog output chan-

SECTION 4: SOFTWARE OVERVIEW PAGE 4-4

 Revision B.002

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

nel 1 operates in its usual fashion (Section 10).

When in the Main screen, press the <F5> key to
display the “+” in the A/O 1 field and use the analog
output channel 1 as a status watch indictor.

38% This field contains the filter loading percentage

(Section 3). It indicates the portion of the TEOM
filter’s total capacity that has been used. Because
this value is determined by the pressure drop of the
main (sample) flow line, the instrument will always
show a nonzero value even if no filter is mounted in
the mass transducer. New filters generally exhibit
filter loading percentages of 15% to 30% at a main
flow rate of 3 l/min, and less at lower flow
rates.TEOM filter cartridges must be exchanged
before this value reaches 100% to ensure the valid-
ity of the data generated by the instrument. At some
point above 100%, the main flow drops below its set
point.If the filter loading percentage is higher than
30% (at a main flow rate of 3 l/min) when a new
TEOM filter is placed on the mass transducer, or if
the lifetime of consecutive TEOM filter cartridges
becomes noticeably shorter, inspect the in-line filter
in the main flow line (Section 12) and replace it, if
necessary.

N This field contains the RS232 mode. It defines the

current function of the 9-pin RS232 connectors on
the front and back panels of the TEOM control unit.
You can select the RS232 mode when in the Set RS-
232 Mode screen (Section 9).

IMPORTANT: Never connect serial devices to the front

and back RS232 ports of the instrument at the same time.
This can cause the RS232 features of the monitor to malfunc-
tion.

U This field contains the protection indicator (Section

11) of the Series 1400a Monitor. It incorporates
three states of password protection:

• Unlocked (U) Mode The user has access to all capabilities of

the instrument.

SECTION 4: SOFTWARE OVERVIEW PAGE 4-5

 Revision B.002

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

• Low lock (L) Mode The user is prevented from editing any
of the system parameters, but may view
all screens and change the operating
mode of the instrument to perform main-
tenance or calibration functions, such
as filter exchanges.

• High lock (H) Mode The user cannot make any changes from
the keypad except for turning off the
high lock mode with the proper pass-
word.

09:39 This field contains the current time (hh:mm). Refer

to Section 6 for instructions on changing the time
and date stored by the instrument.

When you press the down arrow key to view additional information lines, the status
line remains visible at the top of the screen. Because the Main screen displays data
computed by the instrument, none of the data values on this screen can be edited or
changed by the user.

The information lines contain the following information:

Mass Conc This field contains the 10-minute mass concentra-

tion average (µg/m3). This is a sliding average that
is updated every two seconds. This value cannot be
changed by the user.

30-Min MC This field contains the 30-minute mass concentra-

tion average (µg/m3). This is a sliding average that
is updated every 30 minutes on the half hour. This
value cannot be changed by the user.

SECTION 4: SOFTWARE OVERVIEW PAGE 4-7

 Revision B.002

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

01-Hr MC This field contains the 1-hour mass concentration

average (µg/m3). This is a sliding average that is
updated every 60 minutes on the hour. This value
cannot be changed by the user.

08-Hr MC This field contains the mass concentration average

with a user-definable period (2-23 hours) (µg/m3).
This is a sliding average that is updated every 60
minutes on the hour. The default period is 8 hours.
The period can be changed (Section 6), but the
average that this variable generates cannot be
changed by the user.

NOTE: Mass concentration averages of less than 24 hours

can be averaged using data logging equipment to compute
sliding 24-hour averages and 24-hour averages that do not
necessarily start and end at midnight, as well as averages on
other user-defined time scales.

24-Hr MC This field contains the 24-hour mass concentration

average (µg/m3). This is a sliding average that is
updated every 60 minutes on the hour. This value
cannot be changed by the user.

Tot Mass This field contains the amount of mass that has
accumulated on the TEOM filter since the last
instrument reset which is done by turning on the
instrument or pressing the <F1> or <RUN> key.
This value cannot be changed by the user.

Case Temp This field contains the temperature of the TEOM

mass transducer case (set point=50° C, ±0.1° C).
This value cannot be changed by the user.

Air Temp This field contains the temperature of the sample

stream at the base of the heated air inlet (set point=50°
C, ±0.5° C). This value cannot be changed by the
user.

Cap Temp This field contains the temperature of the upper part
of the TEOM mass transducer (set point=50° C,
±0.1° C). This value cannot be changed by the user.

SECTION 4: SOFTWARE OVERVIEW PAGE 4-8

 Revision B.002

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

Main Flow This field contains the actual volumetric flow rate
measured by the main flow controller (set point=3 l/
min). This value cannot be changed by the user.

Aux Flow This field contains the actual volumetric flow rate
measured by the auxiliary flow controller (set
point=13.67 l/min). This value cannot be changed
by the user.

Noise This field contains the mass transducer’s perfor-

mance. This value should be less than “0.10” after
the system has been in Operating Mode 4 for at least
30 minutes. This value cannot be changed by the
user.

Frequency This field contains the oscillating frequency of the

tapered element (TE) in the mass transducer. This
value varies from one Series 1400a Monitor to
another, but generally ranges between 150 and 400
Hz. This value cannot be changed by the user.

4.3.4. EDIT KEY

The monitor is normally in the “Display” or “Browse” Mode, which allows the user
to move from screen to screen to view the system’s operating parameters. However,
in a number of screens, the user may change the unit’s operating parameters. To
change the unit’s operating paramaters, the user must enter the “Edit” Mode.

When you are in a screen that has values that can be changed or edited, press the up
(<↑>) and down (<↓>) arrow keys to select the field to be edited. Then press the
<EDIT> key on the monitor’s keypad to enter the Edit Mode. A “?” will appear on the
screen in place of the “>” cursor. Edit the system parameter and then press the
<ENTER> key to save the change. Press the <ESC> key to exit the Edit Mode while
in any screen.

In certain cases, the instrument will beep when the <EDIT> key is pressed. The
monitor will beep for three different reasons: the selected variable cannot be changed
or edited, the selected variable can be edited only when the monitor is in the Setup
Mode, the monitor is in the low lock or high lock mode (Section 12).

If the monitor is displaying a screen that can be edited, and the monitor beeps when
the user presses <EDIT> key, the user must press the <DATA STOP> key to enter
Setup Mode before attempting to edit a variable.

If the monitor is in the low lock or high lock mode (Section 12), and the user attempts
to edit a variable by pressing the <EDIT> key, the cursor will not change to a “?” and
the monitor will not beep.

New values can be entered in one of two ways:

Direct keypad entry Display the screen that has the operating parameters
that you want to change or edit. Press the <EDIT>
key. Enter a new value directly by pressing the
number keys, including the minus sign and decimal
point keys, if necessary, (Figure 4-5). Then press the
<ENTER> key to save the change. If you make a
mistake while entering the changes on the monitor’s
keypad, press the <BKSPACE> key to erase indi-
vidual characters or the <ESC> key to leave the edit
command. You also can use direct keypad entry to
enter program register codes (PRCs) (Appendix B).
For example, to set the value for “AO1 Var” to the
24-hour mass concentration average in the Set Ana-
log Outputs screen, press the <EDIT> key, <0>,
<6>, <0>, and then the <ENTER> key to save the
change.

SECTION 4: SOFTWARE OVERVIEW PAGE 4-17

 Revision B.002

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

Arrow keys Display the screen that has the operating parameters
that you want to change or edit, and press the
<EDIT> key. Press the up (<↑>) and down (<↓>)
arrow keys to increase or decrease the value of the
variable being edited. To increase the value of the
variable by 10 steps at a time, press the <SHIFT>
key and hold it down while pressing the up (<↑>)
arrow key. To decrease value of the variable by 10
steps at a time, press the <SHIFT> key and hold it
down while pressing the down (<↓>) arrow key. To
increase the value of the variable by 100 steps at a
time, press the <CTRL> key and hold it down while
pressing the up (<↑>) arrow key. To decrease the
value of the variable by 100 steps at a time, press the
<CTRL> key and hold it down while pressing the
down (<↓>) arrow key. Press the <ENTER> key to
save the change. Using the up and down arrow keys
to change a variable is very convenient when chang-
ing a variable that is not entirely numeric. For
example, when in the Set Analog Outputs screen
(Section 9), you can press the <EDIT> key, the up
(<↑>) arrow key and then the <ENTER> key to
change the value of “AO2 Var” from “01-Hr MC”
to “08-Hr MC.” It is generally a good practice to use
the up (<↑>) and down (<↓>) arrow keys to change
the value of alphanumeric variables, such as the
“Month” value in the Set Time screen, and “Max
Volt” and “Jumpers” values in the Set Analog Out-
puts screen.

In certain cases, two editable variables may appear on the same line. For example, in
the Set Temps/Flows screen (Section 6), the average and standard temperature
variables (“T-A/S”) are on the same line. If you want to change the value of these
variables, make sure the Set Temps/Flows screen is displayed on the control unit’s
four-line display. When in the Set Temps/Flows screen, press the press up (<↑>) and
down (<↓>) arrow keys to move the cursor to the T-A/S field, and press the <EDIT>
key. A “?” will appear next to both editable variables on the current display line. Press
the left (<←>) or right (<→>) arrow keys to choose which variable to change. This
causes one of the two “?” indicators to disappear, leaving only one “?” next to the
selected variable. Enter the new value by pressing the appropriate numbers on the
control unit’s keypad.

If the “?” edit indicator is shown on the screen and there is no keypad activity for 10
seconds, the cursor will automatically return to the “>” cursor.

4.3.5. DISPLAY KEY

The display (<DISP>) key (Figure 4-6) allows the user to change the variables that are
displayed on the Main screen. When in the Main screen, press the up (<↑>) and down
(<↓>) arrow keys to move the cursor to the line on which you want the new variable
to appear, and press the <DISP> key. After you press the <DISP> key, a “#” will
appear in place of the “>” cursor to indicate that the instrument is waiting for the input
of a program register code (PRC) (Appendix B) (Figure 4-13). Enter the three-digit
PRC for the new variable that you want to be displayed and press the <ENTER> key.

For example, to bring the current value for the instrument calibration constant to the
current line, press the <DISP> key, <0>, <4>, <2> and then the <ENTER> key. If you
make a mistake while entering this sequence, press the <ESC> key.

Also, the arrow keys can be used to select a PRC after you press the <DISP> key. Press
the up (<↑>) and down (<↓>) arrow keys to increase or decrease the value of the PRC
by 1. To increase the PRC variable by 10 steps at a time, press the <SHIFT> key and
hold it down while pressing the up (<↑>) arrow key. To decrease the PRC variable by
10 steps at a time, press the <SHIFT> key and hold it down while pressing the down
(<↓>) arrow key. To increase the PRC variable to the highest numerical PRC possible,
press the <CTRL> key and hold it down while pressing the up (<↑>) arrow key. To
decrease the PRC variable to the lowest numerical PRC possible, press the <CTRL>
key and hold it down while pressing the down (<↓>) arrow key. Press the <ENTER>
key to save the change.

If the “#” cursor is shown on the screen and there is no keypad activity for 10 seconds,
the cursor will automatically return to the “>” cursor.

5.3.3. FLOW AUDIT PROCEDURE

R&P recommends that the flow audit procedure be performed before initiating your
first sample run. The flow audit procedure checks the flow rates in the Series 1400a
✔ Do not run a flow audit Monitor and can be done with minimal disturbance of the instrument’s normal
procedure during a valid operating configuration. The tolerances in this audit procedure should not be confused
sampling run. with the tighter specifications outlined in the calibration procedures of the Service
Manual.

Perform the ambient air temperature verification (Section 5.3.1), pressure verifica-
tion (Section 5.3.2) and leak check (Section 3) before executing the flow verification
procedure (Section 5.3.3).

Tools Needed
Needed:: Flow audit adapter kit (57-001243)

Materials: None

Follow these steps to perform a flow audit:

1) Press the <F1> or <RUN> key on the control unit’s keypad.

NOTE: Any data generated by the instrument during this audit procedure are
invalid. Therefore, do not run a flow audit procedure during a valid sampling run.
2) Remove the sample inlet from the flow splitter (Figure 5-11).

with “Main Flow” and “Aux OK 4+ 11% NU 09:44
Flow” lines displayed. Main Flow 3.00
Aux Flow 13.66
---------<

7) Confirm that these flows are within ±2% of their set points (3.0 l/
min for the “Main Flow” and 13.67 l/min for the “Aux Flow”). Any
greater deviation may indicate that the in-line filters are plugged
or other blockages exist in the system.
8) Attach a reference flow meter such as a bubble meter, dry gas
meter, or mass flow meter to the top of the flow audit adapter.
This reference flow meter should have been recently calibrated to
a primary standard, have an accuracy of ±1% at 3 l/min and 16.67
l/min, and a pressure drop of less than 0.07 bar (1 psi).
9) Read the total flow (approximately 16.67 l/min) on the reference
flow meter. If you are using a mass flow meter, you must make
any necessary corrections to translate this reading to volumetric
l/min at the current ambient temperature and barometric pres-
sure. No adjustment is necessary in the case of a volumetric flow
meter. The total volumetric flow measured by the reference flow
meter must be 16.67 ±1.0 l/min to be acceptable.
10) Disconnect the bypass flow line from the bypass extension on the
bottom of the flow splitter (Figure 5-15).

12) Read the main flow (approximately 3.0 l/min) on the reference flow
meter. If you are using a mass flow meter, you must make any
necessary corrections to translate this reading to volumetric l/
min at the current ambient temperature and barometric pressure.
No adjustment is necessary in the case of a volumetric flow
meter. The volumetric flow measured by the reference flow meter
must be 3.0 ±0.2 l/min to be acceptable. If the main flow reading
is within acceptable limits, go to step 14. If the main flow reading
is not within acceptable limits, go to step 13.
13) Perform the software and hardware calibrations for the mass flow
controller (Service Manual).
14) Remove the 3/8" Swagelok cap from the flow splitter bypass
extension.
15) Install the bypass flow line onto the flow splitter bypass exten-
sion.
16) Perform a leak check (Section 3.4).
17) Remove the flow audit adapter from the top of the flow splitter.
18) Install the sample inlet onto the flow splitter.
19) Install a new TEOM filter into the mass transducer.
20) Press the <F1> or <RUN> key.

Section 6: Software Setup

This section describes the parameter settings in the software screens that affect the
monitor’s basic operation and sample programming. It also describes the unit’s
operational modes. Do not attempt the procedures described in this section until you
have read Sections 2-5. Appendix A contains all of the instrument’s screens, and
Appendix B contains a complete list of the monitor’s program register codes (PRCs).

6.1. MODES OF OPERATION

The Series 1400a Monitor displays its current operating mode in the upper left-hand
corner of the Main screen (Figure 6-1).

The unit’s operating modes (Figure 6-2) are defined as follows:

Operating Mode 1 This operating mode indicates that the unit has not
begun to compute mass values, because the monitor’s
temperatures and flow rates are stabilizing. The
temperatures and flow rates must remain within a
very narrow range of values (Section 6.3) for 30
minutes before the instrument enters Operating
Mode 2. The monitor always starts in Operating
Mode 1 when it is turned on or reset. Press the <F1>
or <RUN> key to reset the instrument from any
operating mode. This action always causes the in-
strument to enter Operating Mode 1.

Operating Mode 2 This operating mode indicates that the unit has
begun to collect data records, but the monitor has
not yet computed its first total mass value.

Operating Mode 3 This operating mode indicates that the unit has
computed the first total mass value, but mass con-
centration and mass rate values are not yet available.

Operating Mode 4 This operating mode indicates that unit is fully

operational. The monitor normally resides in this
mode. All mass values are being computed by the
instrument.

Setup Mode When the unit is in this operating mode, it continues

to draw a sample flow and maintain operational
temperatures but it does not collect any data. Certain
operating parameters such as temperatures and flow
rates can only be changed in this mode, because
doing so during data collection (Operating Modes
1-4) would affect the data. Press the <DATA STOP>
key to enter the Setup Mode while in any operating
mode. When the unit is in the Setup Mode (S), the
user can change all of the system’s parameters. To
leave the Setup Mode and start data collection, press
either the <F1> or <RUN> key to return the monitor
to Operating Mode 1. If the instrument remains in
the Setup Mode for 5 minutes without the user
pressing any key on the keypad, the monitor will
automatically return to Operating Mode 1.

F-Aux This field contains the setting and current value of

the auxiliary (BYPASS FLOW) flow rate (l/min).
The default setting is 13.67 l/min and can be ad-
justed when the monitor is in the Setup Mode. The
current value can not be edited.

T-A/S This field contains the average and standard tem-

perature (°C) settings. The default setting for both
parameters is 25° C and can be adjusted when the
monitor is in the Setup Mode. The user can use these
values to set the unit’s volumetric flow control
(Sections 6.3.1 and 6.3.2) and to determine how the
unit reports the mass concentration levels (Sections
6.3.3 and 6.3.4). If the instrument has been used
before and the user wants to return it to its original
settings, the user should first re-initialize the unit
(Section 13) before setting the unit’s reporting stan-
dards.

P-A/S This field contains the average and standard atmo-

spheric pressure (atm) settings. The default setting
for both parameters is 1 atm and can be adjusted
when the monitor is in the Setup Mode. The user can
use these values to set the unit’s volumetric flow
control (Sections 6.3.1 and 6.3.2) and to determine
how the unit reports the mass concentration levels
(Sections 6.3.3 and 6.3.4). If the instrument has been
used before and the user wants to return it to its
original settings, the user should first re-initialize
the unit (Section 13) before setting the unit’s report-
ing standards.

Amb Temp This field contains the current ambient temperature

(°C) at the site. This value can not be edited and will
be correct only when the ambient temperature sen-
sor is properly installed (Section 2).

Amb Pres This field contains the current ambient pressure

(atm) at the site. This value can not be edited.

FAdj Main This field contains the main flow adjustment factor.
This value is used during the software calibration of
the mass flow controller (Service Manual). The

SECTION 6: SOFTWARE SETUP PAGE 6-8

 Revision B.003

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

default setting for this parameter is “1.000” and this

value can be adjusted when the monitor is in the
Setup Mode.

FAdj Aux This field contains the auxiliary flow adjustment

factor. This value used during the software calibra-
tion of the mass flow controller (Service Manual).
The default setting for this parameter is “1.000” and
this value can be adjusted when the monitor is in the
Setup Mode.

The Series 1400a Monitor uses mass flow controllers to ensure a constant and precise
flow through the instrument. The mass flow controllers use the actual (active
volumetric flow control setting) or average (passive volumetric flow control setting)
temperature and pressure values to regulate the volumetric flow through the system.
The active volumetric flow control setting (Section 6.3.1) directs the unit to use the
actual ambient temperature and pressure to regulate the volumetric flow through the
system. The passive volumentric flow control setting (Section 6.3.2) directs the unit
to use the average temperature and pressure values to regulate the volumetric flow
through the system. The instrument is delivered with the following temperatures and
pressures settings:

Standard temperature.......... 25° C Standard pressure .. 1 atmosphere (atm)

Average temperature .......... 25° C Average pressure ... 1 atmosphere (atm)

If the user receives the Series 1400a Monitor directly from R&P, the only change that
the user must make, before using the instrument for U.S. EPA-equivalent PM-10
measurements, is to choose how they want the monitor to control the volumetric flow:
actively (Section 6.3.1) or passively (Section 6.3.2). If the user wants to use the
instrument for U.S. EPA-equivalent PM-10 measurements, they must ensure that the
standard temperature is set to 25° C, and the standard pressure is set to 1 atm,
regardless of the values that they entered for the average temperature and average
pressure settings. Also, if the monitor has been used before and the user wants to return
it to its original settings, the user should first re-initialize the unit (Section 13) before
selecting the active or passive volumetric flow control setting.

The unit also uses the parameters in the Set Temps/Flows screen to determine how to
report the measured mass concentration levels. The user can choose to report the mass
concentration levels to actual (Section 6.3.3) or standard conditions (Section 6.3.4).

If the user chooses to set the unit to report the mass concentration levels to actual
conditions, they must they should set the average and standard temperatures to “99,”
and the average and standard pressures to “9” when in the Set Temps/Flows screen

 Revision B.003

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

(Figure 6-6). This will cause the monitor to use the actual ambient temperature and
ambient pressure in its flow rate calculations.

If the user chooses to set the unit to report the mass concentration levels to standard
conditions, they must set the standard temperatures and pressures to the appropriate
standard regulatory values when in the Set Temps/Flows screen (Figure 6-6). This will
cause the monitor to use the standard temperature and pressure values in its sample
volume calculations (Section 1).

NOTE: If the user wants to use the instrument for U.S. EPA-
equivalent PM-10 measurements, they must ensure that the
standard temperature is set to 25° C, and the standard
pressure is set to 1 atm (Section 6.3.4), regardless of the
values that they entered for the average temperature and
average pressure settings.

6.3.1. ACTIVE VOLUMETRIC F LOW CONTROL

The Series 1400a Monitor uses mass flow controllers to ensure a constant and precise
volumetric flow through the instrument. The mass flow controllers use the actual
(active volumetric flow control setting) or average (passive volumetric flow control
setting) temperature and pressure values to regulate the volumetric flow through the
system. The active volumetric flow control setting directs the unit to use the actual
ambient temperature and pressure to regulate the volumetric flow through the system.
The passive volumentric flow control setting directs the unit to use the average
temperature and pressure values to regulate the volumetric flow through the system.
If the user wants the unit to use the actual temperature and pressure to control the
volumetric flow, they should set the average temperature to “99,” and the average
pressure to “9” when in the Set Temps/Flows screen (Figure 6-6).

NOTE: If the user wants to use the instrument for U.S. EPA-
equivalent PM-10 measurements, they must ensure that the
standard temperature is set to 25° C, and the standard
pressure is set to 1 atm (Section 6.3.4), regardless of the
values that they entered for the average temperature and
average pressure settings.

If the user chooses to use the actual temperature and pressure to control the volumetric
flow, they must install the ambient temperature sensor (Section 2). The instrument’s
mass flow controllers measure flow on a mass basis. All of the size-selective inlets
(Section 2), including the PM-10 inlet, operate on a constant volumetric flow basis.
To measure accurate mass concentration levels when using a size-selective inlet, the
user must make a density adjustment to the mass flow controllers using the tempera-
ture and pressure values.

Follow these steps to use the actual temperature and pressure values to
control the volumetric flow:

6.3.2. PASSIVE VOLUMETRIC F LOW CONTROL

The Series 1400a Monitor uses mass flow controllers to ensure a constant and precise
flow through the instrument. The mass flow controllers use the actual (active
volumetric flow control setting) or average (passive volumetric flow control setting)
temperature and pressure values to regulate the volumetric flow through the system.
The active volumetric flow control setting directs the unit to use the actual ambient
temperature and pressure to regulate the volumetric flow through the system. The
passive volumentric flow control setting directs the unit to use the average tempera-
ture and pressure values to regulate the volumetric flow through the system.

The average temperature and average pressure, used by the instrument, may vary with
season and altitude. If the user wants the unit to use the average temperature and
pressure to control the volumetric flow, they should manually adjust the average
temperature and average pressure settings as climatic conditions change. The user
usually has to adjust the average pressure only once for the average barometric
pressure at the sampling site (i.e., station pressure — not adjusted to sea level).
However, the user generally must adjust the average temperature periodically (often
4 times per year) in accordance with changing average ambient temperatures.

IMPORTANT: If you have installed the ambient tempera-

ture sensor on the monitor, you must enter “99” in the
average temperature field and “9” in the average pressure
field.

If the user installs the instrument at an altitude that is different from sea level, the user
must set the average pressure to a value other than 1 atm, so that the instrument can
maintain its proper volumetric flow within acceptable limits. When the user enters an
average pressure of less than 1 atm, it reduces the instrument’s mass flow rate, but
ultimately maintains the appropriate volumetric flow for the altitude.

Similarly, average daily temperatures may not always be 25° C. In such cases, the user
must adjust the average temperature seasonally to account for changes in mean
temperatures. If the user enters an average temperature of less than 25° C in the
system, the mass flow through the sampling head increases so that the proper
volumetric flow remains within acceptable limits.

NOTE: If the user wants to use the instrument for U.S. EPA-
equivalent PM-10 measurements, they must ensure that the
standard temperature is set to 25° C, and the standard
pressure is set to 1 atm (Section 6.3.4), regardless of the
values that they entered for the average temperature and
average pressure settings.

6.3.3. REPORTING TO ACTUAL CONDITIONS

The unit uses the parameters in the Set Temps/Flows screen to determine how to report
the measured mass concentration levels. If the user chooses to set the unit to report the
mass concentration levels to actual conditions, they must set the average and standard
temperatures to “99,” and the average and standard pressures to “9” when in the Set
Temps/Flows screen (Figure 6-6). This will cause the monitor to use the actual
ambient temperature and ambient pressure in its flow rate calculations.

NOTE: If the user wants to use the instrument for U.S. EPA-
equivalent PM-10 measurements, they must ensure that the
standard temperature is set to 25° C, and the standard
pressure is set to 1 atm (Section 6.3.4), regardless of the
values that they entered for the average temperature and
average pressure settings.

IMPORTANT: You MUST install the ambient tempera-

ture sensor on your Series 1400a (AB) Monitor, or install the
upgrade kit on your Series 1400a (AA) Monitor, to set your
unit to report the mass concentration levels to actual condi-
tions.

6.3.4. REPORTING TO STANDARD CONDITIONS

The unit uses the parameters in the Set Temps/Flows screen to determine how to report
the measured mass concentration levels. If the user chooses to set the unit to report the
mass concentration levels to standard conditions, they must set the standard tempera-
tures and pressures to the appropriate standard regulatory values when in the Set
Temps/Flows screen (Figure 6-6). This will cause the monitor to use the standard
temperature and pressure values in its flow rate calculations.

NOTE: If the user wants to use the instrument for U.S. EPA-
equivalent PM-10 measurements, they must ensure that the
standard temperature is set to 25° C, and the standard
pressure is set to 1 atm (Section 6.3.3), regardless of the
values that they entered for the average temperature and
average pressure settings.

IMPORTANT: If your standard regulatory settings are

The Set Hardware screen contains the following information:

Cal Const This field contains the calibration constant, Ko (K0)

(Section 1). You can find your monitor’s Ko on the
label located inside the mass transducer, which is
located inside the sensor unit. Each monitor has a
unique Ko. The “Cal Const” value must match the
value shown on the label inside the mass transducer,
or the mass concentration data will be incorrect.
This parameter can be edited when the monitor is in
the Setup Mode.

Ser Num This field contains the monitor’s serial number. You
can find your monitor’s serial number on the back
panel of the sensor and control units. The “Ser Num”
value must match the number found on the hardware.
This parameter can be edited when the monitor in any
operating mode.

Inst type This field contains the monitor’s instrument type.

This two-letter instrument type is incorporated into
the serial number prefix of the instrument. The
possible variants of the serial number prefix are:
“AA” (140A, 140AA, 14UP), “AB” (140AB) and
“AT” (140AT). This parameter cannot be edited.

Wait Time This field contains the length of time (sec) in which
the temperatures and flow rates must remain (within
a range around their setpoints) before the instrument
changes from Operating Mode 1 to 2. The default
setting is “1800” seconds. This parameter can be
edited when the monitor in any operating mode.

NOTE: R&P recommends that the user set the “Wait Time”
to “1000” or higher to avoid damaging the instrument, and
to maintain accurate data reporting.

MR/MC Ave This field contains the monitor’s MR/MC averaging

time (sec). This value is the length of time over which
total mass values are averaged to compute real-time
mass rate and mass concentration values (Section 1).
The default setting for this value is “300” seconds.
This parameter can be edited when the monitor is in
any operating mode.

SECTION 6: SOFTWARE SETUP PAGE 6-20

 Revision B.003

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

TM Ave This field contains the monitor’s TM averaging time

(sec). This value is the length of time over which
frequency values from the mass transducer are aver-
aged to compute real-time total mass readings (Section
1). The default setting for this value is “300” seconds.
This parameter can be edited when the monitor is in
any operating mode.

XX-Hr MC This field contains the XX-Hr MC parameter. This

value gives the user a choice of averaging times
(hours) shown on the Main screen, following the 1-
hour mass concentration average. The default value
for this parameter is “8,” which causes the monitor
to compute 8-hour averages. The user can select any
averaging time between 2 and 23 hours for this
parameter. This parameter can be edited when the
monitor is in the Setup or Stop All Mode.

Const A The 1400a monitor makes a minor empirically

established adjustment to the mass concentration
data to achieve results comparable to the PM-10
reference methods. This is done using the formula Y
= A + BX. The “Const A” value must be set its
default value of “3.0” to allow the Series 1400a
Monitor to be used as an equivalent method for PM-
10 measurements. This parameter can be edited
when the monitor is in the Setup Mode.

Const B The 1400a monitor makes a minor empirically

established adjustment to the mass concentration
data to achieve results comparable to the PM-10
reference methods. This is done using the formula Y
= A + BX. The “Const B” value must be set to its
default value of “1.03” to allow the Series 1400a
Monitor to be used as an equivalent method for PM-
10 measurements. This parameter can be edited
when the monitor is in the Setup Mode.

Soft Rate The Series 1400a monitor makes “Soft Rate” soft-
ware and hardware adjustments for internal clock
drift correction. This value is set before the instru-
ment leaves R&P and should not be changed, unless
the user loads new software into the instrument. If

the user loads new software into the instrument, the

Soft Rate value will return to its default setting
(“0”). The user must then follow the procedure for
setting the internal clock (Service Manual) to set the
Soft Rate to its appropriate value.

Hard Rate The Series 1400a monitor makes “Hard Rate” soft-
ware and hardware adjustments for internal clock
drift correction. This value is set before the instru-
ment leaves R&P and should not be changed, unless
the user loads new software into the instrument. If

successive writings of data to the circular buffer.
For example, if the user sets this field to “3600,” the
monitor will record data to the internal data logger
every hour. The averaged analog input values (aver-
age wind speed (PRC 147), average wind velocity
(PRC 148) and average wind direction (PRC 149))

Section 7: Status Codes

This section explains the status codes that display on the Main screen and the Status
Codes screen.

The current status condition (Figure 7-1) is located on the upper left-hand corner of
the Main screen. It is an alphanumeric code that indicates the operational status of the
instrument, indicating any status condition that exists.

Whenever a status code (other than “OK”) is displayed on the Main screen, the
instrument automatically turns on the “CHECK STATUS” light (Figure 7-2) on the
front panel of the control unit.

the “CHECK STATUS” light
(A) highlighted.

SECTION 7: STATUS CODES PAGE 7-1

 Revision B.001

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

The status condition can consist of one or more of the following codes:

OK Normal operation. No current status conditions.

M Frequency signal failure. Control unit is not receiv-

ing a frequency signal.

T Temperature(s) outside of operational bounds. The

range is ±0.5° C for the air temperature, and ±0.1°
C for the cap and case temperatures.

F Flow(s) outside of operational bounds. The range is

±0.1 l/min.

X Exchange filter. This status code becomes active

when the filter loading percentage reaches 90%
capacity.

V Voltage low. This status code becomes active when

the AC voltage reading drops below 15 volts.

NOTE: A frequency signal failure (“M”) status condition

automatically triggers the temperature outside of opera-
tional bounds (“T”) status code, because the monitor turns
off the air and case temperature controls when the mass
transducer does not output a frequency.

When in the Main screen, press the <MAIN/STATUS> key on the control unit’s
keypad to display the Status Codes screen (Figure 7-3). The Status Codes screen
provides an explanation of the current status conditions.

Section 8: Viewing Stored Data

Viewing

The Series 1400a Monitor contains a battery-backed circular buffer (internal data
logger) for the storage of historical instrument results (data records). This section
describes how to view data records currently stored in the monitor’s internal data
logger (circular storage buffer). The capacity of the data logger, as measured by the
number of records, depends on the number of data fields (system variables) stored in
each record. The instrument always stores the time, date and station number in each
record, and eight other system variables can be defined by the user in the Set Storage
screen (Section 6).

Figure 8-1 displays the capacity of the monitor’s internal data storage. Because header
information is stored in each record, the capacity of the data logger does not decrease
proportionately with an increase in the number of data fields per record. Data records
can be viewed on the screen of the monitor (Section 8.1) and/or downloaded through
the RS232 port (Section 9). When this buffer is filled, the oldest data points are
replaced with the most recent information (“first in, first out”).

This section describes how to use the 3 user-definable analog outputs, 2 user-definable
contact closure circuits, and 7 analog inputs. This section also explains how to
download data through the RS232 port to a serial printer, personal computer (PC) and
other data capture devices, such as a data logger.

9.1. ANALOG INPUTS

The standard configuration of the Series 1400a Monitor contains six inputs on the
external analog connector (EXT ANALOG) located on the back of the control unit
(Figure 9-1), and one analog input on the two identical 15-pin analog I/O (ANALOG
I/O) connectors located on the front and back of the control unit (Figures 9-1 and 9-
2). These inputs can be configured as ±2 VDC, ±10 VDC full scale (-100% to 100%)
or 4-20 mA. The specification for all analog inputs is an input impedance of 24 K
ohms.

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

For each analog input channel (0-6), the monitor can convert the incoming voltage
signal of 10 VDC, 2 VDC or 4-20 mA into engineering units. Because the instrument
cannot tell whether the jumper for a particular analog input channel is set to 10 VDC
(default), 2 VDC or 4-20 mA, the incoming signal is expressed as a percentage of full
scale (-100% to 100%). For example, if an analog input channel is configured as 10
VDC, -100% represents a voltage of -10 VDC, and 100% represents a voltage of 10
VDC. The location of the analog input jumpers is shown in Figures 9-3, 9-4 and 9-5.

The conversion formula used by the monitor to convert the analog input value to
engineering units is:

Result = Const A + Const B(A/I %FS) + Const C (%A/I FS)2

“Const A,” “Const B” and “Const C” may be defined differently for each channel, and
“A/I %FS” is an analog input’s percentage of full scale.

In the instrument’s default configuration, the Const A and Const C values are set to
“0,” and the value of Const B is set to “1.” In Figure 9-6, the average analog inputs
displayed are the percentage of full scale.

If the user has installed an optional wind vane/anemometer on the monitor in which
a 5 VDC output represents a 0-180 km/h wind speed, and the input channel is
configured in hardware as 10 VDC, the values of Const A, Const B and Const C should
be entered as:

A=0 B = 3.6 C=0

If the user has installed an optional wind vane/anemometer on the monitor in which
a 5 VDC output represents a 0-360° wind direction, and the input channel is
configured in hardware as 10 VDC, the values of Const A, Const B and Const C should
be entered as:

A=0 B = 7.2 C=0

The Set Analog Outputs screen contains the following information:

Max Volt This field contains the full scale voltage setting. The
range for this variable is 1, 2, 5, or 10 VDC. If you
are unable to select 5 or 10 VDC while setting this
variable, then you must change the setting for the
Jumpers variable to 10 VDC.

AO1 Var This field contains the PRC value of analog output
1, that will be output. Whenever a variable is as-
signed to one of the analog output channels, the
program register codes (PRCs) for the variable’s
name, minimum value, and maximum value are all
assigned to that channel. In the case of a 10 VDC
output, the minimum value for the selected output
variable is set to 0 VDC and the maximum value is
set to 10 VDC. The behavior of analog output
channel 1 can be modified if the user chooses to use
the channel as a status indicator. Refer to Section
4.3.1.3 for information concerning the Analog Out-
put 1 mode.

AO1 Min This field contains the minimum value setting of the
output PRC for analog output 1.

AO2 Max This field contains the maximum value setting of

the output PRC for analog output 1.

AO2 Var This field contains the PRC value of analog output
2, that will be output. Whenever a variable is as-
signed to one of the analog output channels, the
program register codes (PRCs) for the variable’s
name, minimum value, and maximum value are all
assigned to that channel. In the case of a 10 VDC
output, the minimum value for the selected output
variable is set to 0 VDC and the maximum value is
set to 10 VDC.

AO2 Min This field contains the minimum value setting of the
output PRC for analog output 2.

AO2 Max This field contains the maximum value setting of

the output PRC for analog output 2.

AO3 Var This field contains the PRC value of analog output
3, that will be output. Whenever a variable is as-
signed to one of the analog output channels, the
program register codes (PRCs) for the variable’s
name, minimum value, and maximum value are all
assigned to that channel. In the case of a 10 VDC
output, the minimum value for the selected output
variable is set to 0 VDC and the maximum value is
set to 10 VDC.

AO3 Min This field contains the minimum value setting of the
output PRC for analog output 3.

AO3 Max This field contains the maximum value setting of

the output PRC for analog output 3.

Jumpers This field contains the jumper settings of the three

analog output channels in the analog output hard-
ware. In the default configuration, the analog output
jumpers are set to 10 VDC. In most cases, the value
for the jumpers variable should remain at 10 VDC,
and no change must be made to the hardware.

In a typical installation, one of the monitor’s three analog outputs will be defined as
the instantaneous mass concentration average (PRC 8), and this output will be scaled
for output over a range of -100 to +900. This output is transmitted to a data logger that
is set for a 1-hour averaging time.

The instrument has an analog output resolution of 12 bits including the sign. If the user
wants the monitor to produce 1 or 2 VDC analog outputs, the user can change the
jumpers in the monitor to their alternate setting of 2 VDC to receive the best voltage
resolution.

An appropriate analog output voltage setting depends on the input characteristics of

the instrument receiving the signal (for example, the data logger) from the monitor.
Consult the operating instructions that came with that instrument to determine what
range of voltages it will accept, and adjust the Series 1400a Monitor’s analog output
voltage levels from their factory settings (10 VDC) to correspond with it, if necessary.

9.4.4. DOWNLOADING DATA — ONE-WAY COMMUNICATION

The user can download data directly from the unit to a serial printer, personal
computer (PC), or other serial data recording device. The instructions in this section
explain a one-way data tranmission, which is transmitting data only from the unit to
another data capture device.

9.4.4.1. FAST STORE OUT MODE

The user can set up the monitor to download data records using the Fast Store Out
Mode before they have been recorded, while they are being recorded, or after they
have been recorded. Data transmitted through the Fast Store Out mode are delimited
by commas for simplified use in spreadsheet programs. Keypad response to user
inputs is diminished when the instrument is in the Fast Store Out Mode due to the high
rate at which the RS232 port is accessed. This does not have any effect on the
collection, calculation or storage of data in the instrument.

Follow these steps to download data using the Fast Store Out Mode:

1) Connect one end of the 9-to-9 pin computer cable to one of the
RS232 ports on the control unit.
2) Ensure that nothing is connected to the other RS232 port of the
control unit.
3) If your personal computer (PC) or other serial data recording
device is equipped with a 9-pin RS232 connector, go to step 4. If
your PC or other serial data recording device is equipped with a
25-pin connector, go to step 5.
4) Plug the other end of the 9-to-9 pin computer cable into the 9-pin
RS232 port of your PC or other serial data recording device. Go
to step 8.
5) Locate the 9-to-25 pin computer cable adapter.
6) Plug the 9-to-25 pin computer cable adapter into the 25-pin port
on your PC or other serial data recording device.
7) Plug the other end of the 9-to-9 pin computer cable into the 9-to-
25 pin computer cable adapter. Go to step 8.
NOTE: Do not use the 9-to-25 pin modem cable to connect the control unit with
the PC or other serial data recording device. The 9-to-25 pin modem cable is
configured for use only with a modem.

Section 10: RPComm Software

RPComm is a communications software package developed for Windows 9x/NT/

2000/Me to provide interactive remote communications with R&P instrumentation.
RPComm also comes in a version for handheld computers/Windows CE. Refer to the
Palm Pilot PC Operating Manual for instructions on using the PalmOS-based
handheld computer to download data from the Series 1400a Monitor. Refer to
Appendix A for a complete list of RPComm software screens.

RPComm enables the user to:

• Download data stored in the instrument’s data storage buffer
• Schedule automatic data downloads
• View and graph downloaded data
• View a real-time graph of selected variables
• Remotely operate the unit using a virtual keypad
• Make multiple connections.

System requirements for running RPComm software are:

• Pentium processor
• 64 megabytes (MB) of random access memory (RAM)
• 40 MB of hard drive space.

RPComm has two communication modes — direct and modem. Direct communica-
tion is accomplished when the unit has a direct cable connection with a personal
computer (PC). Modem communication is accomplished when the unit has a connec-
tion with a PC through the use of a modem and phone line (Appendix H). Before
modem communication is attempted, direct communication must be successfully
completed. This will ensure that the PC and unit have been set up properly for
communications.

10.2.2. CREATING A NEW CONNECTION

A connection is the hardware, software and proper settings that enable information to
travel between your personal computer (PC) and unit. The hardware part of the
connection is established by using a 9-to-9 pin cable (Section 6). The software
connection is established when RPComm is started. The proper settings must be set
up within RPComm to complete the connection.

NOTE: The Windows operating system screens shown in

this section are from the Windows 98 operating system.
These screens may vary slightly from your computer’s
screens if you are operating RPComm under other Windows
operating systems.

Follow these steps to create a new connection:

1) When in the Connection List screen (Figure 10-3), select the New

Connection icon on the toolbar. The Connection Type

screen will be displayed (Figure 10-6).

8) The connection should now be ready for use. However, because

different instruments require different RS232 port settings, these
values must sometimes be changed. Refer to Section 10.2.2.1 for
information on confirming or changing these settings. If you want
to define additional new connections, go to step 9. If you do not
want to define additional new connections, go to step 11.
9) Repeating steps 1-8 to define each new connection. These new
connections can connect various instrument types. When you
have completed defining your new connections, you can save
them in a “ connection group.” If you want to save your new
connections in a ““connection
connection group,” go to step 10. If you do not
want to save your new connections in a “ connection group,” go
to step 11.
10) Ensure that all of your new connections are displayed in the
Connection List screen. Ensure that the monitor’s RS232 mode is
set to “AK Protocol” (Section 9). When in the Connection List
screen, select the “File” pull down menu and highlight “Save

10.2.3. DOWNLOADING DATA WITH RPCOMM

R&P instruments keep track of which records have been downloaded by using
“storage pointers.” These storage pointers indicate the most recently retrieved data
record, and serve as the starting point for future downloads. Every time RPComm
downloads data records from the Series 1400a Monitor, the unit’s storage pointer is
moved to the last data record that was downloaded.

The user can download all the data that are stored in the unit’s internal data logger
beginning at the storage pointer. The storage pointer is a “place marker” in the unit’s
data logger. It indicates to the RPComm program where the data download should
begin. After the data have been downloaded, the unit sets the storage pointer to the end
of the internal data storage buffer, so that the next time data are downloaded, only new
data records are transmitted. However, if the user wants to download specific records
(for example, from a particular date), they can change the position of the storage
pointer within the data storage buffer (Section 10.2.3.1). Also, you can move the
storage pointer to re-download data that has been lost from your personal computer
(PC), or to skip forward to download more recent data records.

NOTE: The Windows operating system screens shown in

this section are from the Windows 98 operating system.
These screens may vary slightly from your computer’s
screens if you are operating RPComm under other Windows
operating systems.

10.2.3.1. SETTING THE STORAGE POINTER POSITION

Toggles between the two possible x-axis scales: date and time, and time
only. This does not affect the way the data are displayed on the graph.

These two boxes define the number of axis divisions on

the graph. The left-hand box refers to the x-axis and the
right-hand box refers to the y-axis. The number of divi-
sions on the axis can be set to 5, 10, 15 or 20. Increasing the number of
divisions results in a finer axis grid. Decreasing the number of divisions
results in a courser axis grid. This does not affect the way the data are
displayed on the graph.

The Series 1400a Monitor offers three levels of keypad locking: unlock mode, low
lock mode, and high lock mode. The Main screen displays the current keypad locking
level on its status line (Figure 11-1). The instrument is always in the unlock mode
when it is first shipped from R&P, allowing the user full access to all of the functions
of the monitor.

12.1.1. EXCHANGING THE LARGE IN -LINE FILTERS

The large in-line filters (57-002758) are located on the main (SENSOR FLOW) and
auxiliary (BYPASS FLOW) lines on the back of the control unit. These filters
prevent contamination from reaching the flow controllers. You should replace the
large in-line filters immediately following a TEOM filter cartridge exchange. This
allows you to exchange the large in-line filters during the 30-minute flow and
temperature stabilization period (Section 4).
✔ The instrument must be

As of February 2001, R&P began manufacturing the Series 1400a Monitor with newly
designed mass flow controllers (the “Second-Generation Flow Controller Design”) in
the control unit. If you purchased your Series 1400a Monitor before February 2001,
or if the serial number on your monitor is 140AB234170011 or below, your control
unit has the original version mass flow controllers. If you purchased a monitor with
the original mass flow controller design, follow the instructions in Appendix J. If your
monitor has the “Second-Generation” mass flow controllers installed, refer to the
Service Manual for the mass flow controller software and hardware calibration
procedures. Also, if you purchased the Flow Controller Upgrade Kit (55-7758) and
installed the Second-Generation mass flow controllers in your Series 1400a Monitor,
refer to the Service Manual for the mass flow controller software and hardware
calibration procedures.

The verification intervals provided above are guidelines. Requirements for verifica-
tions are site-specific, and may vary from one location to another.

12.2.1. MASS TRANSDUCER CALIBRATION VERIFICATION

The calibration of the mass transducer in the Series 1400a monitor is determined by
the mass transducer’s physical mechanical properties. Under normal circumstances,
the calibration does not change materially over the life of the instrument. Contact R&P
if the results of the verification procedure indicate that the a calibration constant has
changed by more than 2.5% from the original R&P calibration constant. You can
locate the original R&P calibration constant inside the mass transducer (Figure 12-
11).

Figure 12-11. Calibration

constant (K0) inside the
mass transducer.

Calibration
constant

Before the Series 1400a Monitor is shipped to the customer, it is calibrated with a new,
pre-weighed TEOM filter installed in its mass transducer as a calibration weight.
Because the mass of the filter cartridge with particulate matter differs from the mass
of a new filter cartridge by only a small fraction, calibrating the system with a
calibration mass equivalent to the filter mass allows all measurements to be made at
essentially the same operating point as the original calibration. Refer to Section 1 for
a detailed explanation of how the calibration constant, K0, is derived.

When a power failure occurs and then power is returned to the instrument, the Series
1400a Monitor automatically resets itself. It will enters the same RS232 mode that it
was set at before the power failure occured. Upon starting up again, the instrument
waits until temperatures and flow rates have stabilized for 30 minutes before
automatically resuming data evaluation and collection. Operating parameters, such as
temperature and flow settings, are maintained in the system’s battery-backed CMOS
memory. The system also contains a battery-backed clock/calendar.

Section 14: ACCU System

The Automatic Cartridge Collection Unit (ACCU) (Figure 14-1) measures particulate
mass concentrations in real time and collects particulate matter on various filter media
under microprocessor control.

Figure 14-1. Control unit

(A) and the ACCU System
(B).

The ACCU System also samples ambient particulate matter independently for
selected chemical analysis by using the auxiliary (bypass) flow of flow splitter-
equipped systems and the microprocessor in the Series 1400a Monitor. The 13.67 (or
optional 14.67, or 15.67) l/min bypass flow from the flow splitter is carried through
the ACCU System to the auxiliary flow controller in the control unit (Figure 14-2).

configuration with ACCU
System installed.

Inside the ACCU System, a bank of solenoid valves redirects the bypass sample
stream through one of eight sampling devices mounted inside the unit (not included
with the system). These sampling devices can include 25, 37 or 47 mm filter holders
with the user’s choice of filter media, polyurethane foam (PUF) samplers, or other
filter pack/tube combinations suitable for the 13.67, 14.67 or 15.67 l/min flow rate.

SECTION 14: ACCU SYSTEM PAGE 14-2

 Revision B.002

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

The ACCU System is connected to the Series 1400a Monitor electronically by a 10-
meter cable that connects to the ACCU connector on the back panel of the monitor’s
control unit (Section 2). The cable carries the signals that activate the valves in the
ACCU System. The user can specify the conditions under which each of the ACCU
System’s eight flow channels is opened using the monitor’s software (Section 14.4).
The flow through the ACCU System can be governed by such factors as the real-time
mass concentration, time of day, day of the week, or analog signals generated by other
devices such as wind speed or wind direction anemometers.

SECTION 14: ACCU SYSTEM PAGE 14-3

 Revision B.002

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

14.1. PRINCIPLE OF OPERATION

The ACCU System contains one internal bypass flow line and eight user-definable
flow lines that normally contain one collection cartridge each. The ACCU System
directs the auxiliary (bypass) flow from the flow splitter of the monitor through one
of the eight collection cartridges, or the internal bypass line. Within the unit,
conductive tubing is used to minimize the static attraction effects of particulate matter
to the tubing walls (Figures 14-3 and 14-4).

Figure 14-3 (left). ACCU

System with enclosure door
open.

Figure 14-4 (right).

Schematic drawing of the
ACCU System.

The control unit closely monitors the bypass flow rate through the ACCU System to
ensure the integrity of a total flow volume of 16.67 l/min through the sample inlet. If
a cartridge installed in the ACCU enclosure causes the bypass flow to deviate from
the standard 13.67 l/min by ± 0.40 l/min, this cartridge is not used again until the user
exchanges the cartridge and resets the channel. To indicate that a cartridge has caused
a high pressure drop, the monitor places a negative sign in front of the value for that
channel’s total flow volume.

Using the monitor’s software, the user defines the conditions under which each of the
eight ACCU channels operates. Only one channel is active at any one time. Every 10
seconds, the instrument determines which of the ACCU System’s eight channels
should currently be active. The unit systematically checks the collection criteria for
each channel (starting at channel 1) and determines whether that criteria are met. If
the criteria are met, the system activates the channel for the next 10 seconds. If the
criteria for channel are not met, the instrument performs the same evaluation for the

SECTION 14: ACCU SYSTEM PAGE 14-4

 Revision B.002

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

next channel. This process continues through the successive channels in the ACCU
System until the monitor finds a channel whose operating conditions are currently
met. If none of the channels meet the conditions for operation, the monitor diverts the
flow is diverted through the internal bypass flow line for that 10-second period.

If the monitor has disqualified a channel because the pressure drop of the installed
cartridge causes the bypass flow to fall outside of the acceptable limits, the instrument
skips over this channel when evaluating the cartridges for operation. For example, if
channels 1, 2 and 3 fail to meet the criteria for activation and channel 4 has been
disqualified because of a high pressure drop, the monitor evaluates channel 5 after it
evaluates channel 3.

Because channel 1 is always evaluated first, this cartridge can be used to override the
settings of the remaining channels. For example, if channels 2 through 8 are defined
by time of day (e.g., midnight to 3:00 a.m.), channel 1 could be used to capture all
episodes in which the particulate matter concentration exceeds 200 µg/m3. In this case,
the bypass sample stream would pass through cartridges 2 through 8 according to the
time of day, except when the particulate matter concentration measured by the
monitor exceeds 200 µg/m3.

If the user anticipates that a particular set of qualification criteria will result in a
cartridge overload, R&P recommends that the user define two or more neighboring
cartridges with the same criteria. For example, if channels 5 and 6 are both defined
with the same criteria and channel 5 later becomes disqualified because its pressure
drop is too high, the bypass flow would jump over channel 5 to channel 6 which would
continue testing with the same criteria as channel 5.

R&P recommends that the user exchange cartridges and define ACCU channels only
when the monitor is in Setup mode, so that the collection of mass concentration data
is not affected by such changes.

The ACCU System is active only when the instrument is collecting data in Operating
Modes 1, 2, 3, or 4. The monitor always passes the sample stream through the internal
bypass of the ACCU System when the instrument is in the Setup Mode or the Stop
Mode. After the user leaves the Setup Mode or the Stop Mode by pressing the <F1>
or <RUN> key, the ACCU System will become active after one minute. The monitor
also waits one minute to activate the ACCU System after the monitor is turned on.

14.4.1.3. ACCU SAMPLING BY CONCENTRATION LEVEL

To define an ACCU channel to be active only when the short-term mass concentration
is higher than 100, you would first enter PRC 8 (“Mass Conc”) in one of the PRC
variable fields of the channel (Section 14.4). Then you would enter “100” in the
minimum permissible value field, and an arbitrarily large value that is not expected
to be exceeded, such as “10000,” in the maximum permissible value field (Figure 14-
21).

14.4.1.4. EPISODIC SAMPLING

The ACCU System can be configured to capture user-defined episodes through the
use of a special code. When operated in this manner, each episode is sampled on one
user-defined ACCU channel. Once a channel has been activated and used, the monitor
will not sample on the channel again until the user resets that channel (Section 14.6).
✔ Episodic sampling
collects each user-defined To capture a user-defined episode, you must define two or more consecutive ACCU
episode on a different
ACCU channel. channels in an identical manner. For example, you would first enter PRC 98 (“Curr
Chan”) in one of the PRC variable fields of two or more consecutive ACCU channels
(Section 14.4), such as ACCU channel 1 and 2. Then you would define the minimum
and maximum permissible values for the episode that you would like to capture.

In Figures 14-22, 14-23 and 14-24, ACCU channels 1, 2 or 3 are activated whenever
the current average of “A/I 0” ranges between “50” and “100.” ACCU channel 1 is
used for the first episode that meets this criterion, followed by channels 2 and 3.

Be sure to use great caution when defining episodes. Variables with broad fluctua-
tions, such as 10-minute mass concentrations, should not be used because they may
vary greatly around the trigger point and cause undesired cycling through the ACCU
channels. For this reason, you should set the ACCU channel to measure 30-minute
mass concentration averages, instead of 10-minute mass concentrations.

SECTION 14: ACCU SYSTEM PAGE 14-28

 Revision B.002

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

14.4.1.5. TIME SAMPLING

The ACCU System can be configured to sample each ACCU channel for predefined
periods of time after a specific set of conditions is met on channel 1. The sampling
criteria assigned to channel 1 are used to begin a sampling sequence that starts with
channel 1 and ends with channel 8. The user assigns the length of time that each
channel is active.

To set up the ACCU System for triggered sampling by time, the user must enter PRC
100 (“Time”) as the first variable of each flow channel definition. Set the minimum
permissible value field to “0.” Then set the maximum permissible value field to the
length of time (seconds) that you want the flow channel to be active.

You must enter the conditions to be tested in ACCU channel 1 to trigger the beginning
of sampling. No additional conditions besides PRC 100 (“Time”) should be entered
into the remaining flow channels (ACCU channels 2-8).

For example, to set the ACCU System to begin sampling on channel 1 when the 30-
minute mass concentration average exceeds 100 µg/m3, with a sampling period of 60
minutes (3600 sec) on all flow channels, you would display ACCU channel 1 and set
the first PRC variable field to PRC 100 (“Time”), with a minimum permissible value
of “0” and a maximum permissible value of “3600.” Then you would set the second
PRC variable field of ACCU channel 1 to PRC 57 (“30-Min MC”), with a minimum
permissible value of “100.00” and a maximum permissible value of “9999.00”
(Figure 14-25).

After you entered the proper PRC variables and values in channel 1, then you would
display the rest of the ACCU channels and set the first PRC variable field to PRC 100
(“Time”), with a minimum permissible value of “0” and a maximum permissible
value of “3600” (Figures 14-26 and 14-27).

them.

14.4.1.6. SEQUENTIAL SAMPLING

The ACCU System can be configured to sample on a certain number of channels for
a predetermined amount of time, and then later return to those channels and sample
on them again for the same amount of time. The user assigns the length of time during
which each channel is active.

To set up the ACCU System for sequential sampling, the user must enter PRC 100
(“Time”) as the first variable of each flow channel in the sequence. Set the minimum
permissible value field to the length of time (seconds) that you want each flow channel
to be active. Then set the maximum permissible value field to “0.”

You also may enter additional conditions to define each channel, in conjunction with
the “Time” variable. For example, you could set ACCU channel 1 to sample for 1 hour
without any additional conditions (Figure 14-28). Then you could set channel 2 to
sample for 1 hour only if the 30 minute mass concentration average exceeds 100 µg/
m3 (Figure 14-29).

If the 30-minute mass concentration average does not meet this minimum value, the
ACCU System will skip channel 2 and cycle to channel 3 (Figure 14-30), where it will
sample for 60 minutes, again without additional conditions. After the ACCU System
has exposed all of the flow channels for their predefined lengths of time, the
instrument will return to channel 1 and begin the sampling sequence again.

The ACCU System will continue sequential sampling in this manner until the user
stops the sampling routine, or until the monitor disqualifies a channel because the
pressure drop of the installed filter cartridge causes the bypass flow to fall outside of
the acceptable limits (Section 7).

Appendix C: Two-W
Two-Way Serial Communication
wo-Way

The Series 1400a Monitor supports two serial communication protocols: the AK
Protocol and the German Ambient Network Protocol. These protocols permit a locally
or remotely located computer to obtain information electronically from the unit.
These protocols are described in this appendix.

C.1. AK PROTOCOL

The AK Protocol allows the user to query the present value of any system variable
remotely, and allows the user to change those system variable values. The user also
can download information from the internal data logger. The RPComm software
program uses this protocol for two-way communication directly to a personal
computer or through a modem. The following AK Protocol commands are presented
in detail on the following pages:

AREG Ask Register Command. The user can query the Series 1400a
Monitor for the current value of any system variable (Appendix B).

EREG Enter Register Command. The user can assign a new value to any
system variable. Great care must be taken when using this command,
as the value of variables should only be changed when the monitor
is in the appropriate operating mode.

SFxx Set Function xx Command. The user can send commands using the
<RUN> key and the <DATA STOP> key to the instrument. Each
command is designated by a two-digit code, xx.

ASTO Ask Storage Command. The user can download a specified number
of records from the internal data logger from the current position of
the data storage pointer. The location of this storage pointer may be
defined by the SSTO command. The values on each line of output are
delimited by commas.

SSTO Set Storage Command. The user can change the location of the data
storage pointer in the internal data logger, and is used in conjunction
with the ASTO command described above. The data storage pointer
is always located immediately after the last record transmitted
through the RS232 port via the AK Protocol. If the circular buffer
overwrites this location or if the ASTO or SSTO commands have not
been used, the data storage pointer is positioned at the oldest record
in the internal data logger.

D.2.4. UPDATING THE LIST OF PROGRAM REGISTER CODES IN RPCOMM

NOTE: Refer to Section 10 for further information on using

the RPComm software program.

All R&P instruments have a list of system variables that is specific to that type of unit.
A system variable is any value that is entered into, calculated by, or measured by the
instrument. This list of system variables is called the “program register code” (“PRC”)
list.

When the monitor’s software is modified, the PRC list often is affected; usually, new
PRCs must be added for software enhancement. If there are new PRCs, then the PRC
list must be updated within the RPComm software program. This can be accom-
plished by:

1) The entire RPComm program can be downloaded from the R&P website
(www.rpco.com) and installed on the computer, as described in Section
D.2. However, this is necessary only if the revision number of the
RPComm software program has changed. Changes to the unit’s operat-
ing software do not always require that you download the new RPComm
program.

2) A new PRC list can be downloaded from R&P’s website and installed on
your computer. This will update the PRC list within RPComm without
requiring the user to reinstall the entire program.

Follow these steps to update the PRC list within RPComm:

1) Go to the RPComm directory on your computer’s hard drive and

look at the files. The PRC lists are located in this directory. Deter-
mine which PRC list revision you have in your RPComm
directory. The file name for the PRC lists have the following
format:
Rp{instrument}n.nnn
where: {instrument} = instrument model (2000FRM, 2025, 1400 or 5400)
n.nnn = PRC list revision
2) Go to the Software to Download area of the R&P website as de-
scribed in Section D.1 (Figure D-6). If there is a new PRC list
available for the Series 1400a Monitor, it will be listed on this web
page.

APPENDIX D: INSTALLING NEW SYSTEM SOFTWARE PAGE D-33

 Revision B.002

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

3) There may be multiple PRC lists on this page, one for each instru-
ment that RPComm supports. Determine if there is an updated
PRC list for the Series 1400a Monitor. Select the appropriate PRC
list and save it to a file.
NOTE: Be sure to remember what folder the PRC list file is saved in.
4) Disconnect from the World Wide Web.
5) If RPComm is running, exit the program.
6) Copy the downloaded PRC list to the RPComm directory on your
computer’s hard drive. The next time you execute RPComm, the
program will automatically use the new PRC list in its operations.

Appendix G: Inlet Maintenance

This appendix contains maintenance procedures for the PM-10 inlet, modified PM-
10 inlet, sharp cut cyclone (SCC) PM-1 and PM-2.5 inlets, old style PM-1 and PM-2.5
cyclone inlets, and the in-line PM-2.5 ACCU inlet.

G.1. CLEANING THE PM-10 AND MODIFIED PM-10 INLETS

Supplies and tools recommended for maintenance:

Ammonia-based, general-purpose cleaner

Cotton swabs
Small soft-bristle brush
Paper towels
Distilled water
Silicone-based stopcock grease
Small screwdriver
Small crescent wrench
Pocket knife

R&P recommends cleaning and maintaining the PM-10 inlet every 1 to 3 months of
continuous operation. This includes removing the inlet from the unit, cleaning it and
checking its O-ring for signs of damage or wear. Because the PM-10 inlet is similar
in construction to the modified PM-10 inlet, the maintenance procedures are the same
for both inlets.

G.1.1. REMOVING THE INLET

Follow these steps to remove and disassemble the inlets:

1) To remove the inlet, lift the entire inlet assembly upward off the
flow splitter.
2) Remove the rain jar and set it aside.
3) Disassemble the upper and lower inlet halves by unscrewing,
counterclockwise, the top acceleration assembly from the lower
collector assembly (Figure G-1).

G.2. MAINTENANCE OF SHARP CUT CYCLONE (SCC) INLETS

The sharp cut cyclone (SCC) is a second stage inlet and is available in PM-1 (Figure
G-15) and PM-2.5 (Figure G-16) configurations. In Series 1400a Monitor applica-
tions, it is used in conjunction with a PM-10 or modified PM-10 inlet (Figure G-17).

The exact maintenance interval between cleanings of the SCC depends on the
particulate matter mass concentration and composition in the ambient air. Field and
laboratory experience indicate a required cleaning interval of three to four weeks, or
more. R&P suggests that the user clean the SCC inlet more frequently until opera-
tional experience allows better determination of proper cleaning intervals based on
your local conditions.

Because the sharp cut cyclone (SCC) PM-1 inlet is similar in construction to the SCC
PM-2.5 inlet, the maintenance procedures are the same for both inlets.

APPENDIX G: INLET MAINTENANCE PAGE G-13

 Revision B.001

G.3. MAINTENANCE OF OLD STYLE PM-2.5 AND PM-1 CYCLONE INLETS

Because the old style PM-1 and PM-2.5 cyclone inlets (Figure G-22) are of similar
construction, the procedure for maintaining them is identical. The cyclone must be
cleaned periodically to prevent buildup of particulate matter and contaminants. R&P
recommends a cleaning rate of once every one to three months. The frequency for
routine maintenance may depend upon the average concentration of the particulate
matter and/or the species being sampled.

H.2. SETTING UP RPCOMM FOR USE WITH A MODEM

NOTE: The Windows operating system screens shown in

this appendix are from the Windows 95 operating system.
The screens may vary slightly if you are operating RPComm
under other Windows operating systems.

The first two steps of this procedure describe how to set up the unit for direct
communication. Direct communication must be successfully completed (Section
10.1) before modem communication is attempted. This will verify that RPComm and
the Series 1400a Monitor have been configured properly. Refer to Section 10 for
instructions on obtaining, installing and using RPComm.

Follow these steps to set up the unit for modem communications:

1) Set up the Series 1400a Monitor for direct communications (Sec-

tion 10.1).
2) Create a new direct connection (Section 10.2.2) and verify that
the unit is communicating properly.
NOTE: If the connection is successful, the unit’s serial number will be displayed
at the top of the screen. If the connection is not successful or if there is no unit
attached, then the serial number field will be blank or will display “99999.”
3) When the RPComm and instrument configurations have been
verified, disconnect the direct connection.
4) Set up the unit for modem communications (Section H.1).
NOTE: R&P recommends that the modem connections be tested before the unit
is placed in the field. The test will require the use of two phone lines.

H.3. SETTING UP THE SERIAL SWITCHING DEVICE

For applications where two or more R&P instruments are installed at the same site,
a serial switching device can be installed to allow communications with each
instrument (including non-R&P serial devices) using one phone line. The serial
switching device enables communication to occur with multiple instruments (includ-
ing non-R&P serial devices) with the use of only one phone line. Command codes can
be sent over the phone line to trigger a particular serial port and, therefore, allow
communication with the connected instrument. RPComm can be configured to
operate with these devices and send the required command codes.

H.3.1. MULTIPLE R&P INSTRUMENTS OF THE SAME M ODEL

Refer to this section if you are connecting two or more R&P instruments of the same
model to a serial switching device.

Follow these steps to set up a serial switching device:

1) Set up the unit for modem communications (Section H.1). Verify

that modem communications to each instrument are successful
before adding the serial switching device.
2) Obtain a serial switching device from a commercial manufac-
turer. R&P has found that devices manufactured by Black Box
Corp. work well with its instrumentation, although other devices
also should function properly. The part number and cost of the
device will vary depending on how many serial devices the user
wishes to connect to it.
3) From the serial switching device’s documentation, determine the
command codes required to activate each serial port being used.
4) Unplug the serial cable, and its adapter(s), from the modem and
plug the cable assembly into the serial switching device. Follow
the instructions provided with the serial switching device and
connect it to the modem.
NOTE: R&P recommends that the serial switching device’s connections be
tested before the unit is placed in the field. This test requires the use of two phone
lines.
5) When in the Connection List screen (Figure H-1), select the name
of the connection used to verify the modem connection above

and then select the Edit Selected Connection icon. The

Connection Type screen will display (Figure H-2).

APPENDIX H: MODEM COMMUNICATIONS PAGE H-11

6) When in the Connection Type screen, ensure that the correct

instrument type is selected and select the “Settings” button to
display the AK Protocol Setup screen (Figure H-3).
7) Examine the list of command codes on the right-hand side of the
AK Protocol Setup screen. Select the correct series of command
codes needed to trigger the desired instrument. As codes are
chosen, they will appear on the bottom of the screen in the Con-
nection Command box. If a code is entered incorrectly, the user
can delete the incorrect code by selecting the code in the Con-
nection Command box and pressing the “Delete” key on your
computer’s keyboard.
8) The remaining portions of the screen should have been set while
establishing the modem connection (step 1). Do not modify these
settings.
9) Select the “OK” button to exit the AK Protocol Setup screen. The
Connection Type screen will display.
10) When in the Connection Type screen, select the “OK” button to
finish the connection setup.
11) To initiate a modem connection to a selected instrument, high-
light the connection name on the Connection List screen (Figure

H-1) and select the Connection icon on the tool bar. The
connection to the instrument will be initiated and the proper
command codes will be sent to the serial switching device. When
communication is established, the Download Data screen will
display (Figure H-7).
NOTE: If the connection is successful, the unit’s serial number will be displayed
at the top of the screen. Ensure that the correct serial number is displayed to verify
that the proper command codes were sent and that the serial port trigger is
functioning properly. If the connection is not successful or if there is no
instrument attached, then the serial number will be blank or will display “99999.”
If the modem loses its connection, wait at least 1 minute before trying to establish
another connection. This allows the modem to reset itself.
12) RPComm can now be used as described in Section 10.
13) To connect to a different instrument through the serial switching
device, the current connection must be terminated. Select the

Disconnect icon on the tool bar to terminate the current

connection.

H.3.2. MULTIPLE R&P INSTRUMENTS OF DIFFERENT MODELS

Refer to this subsection if two or more R&P instruments of different models are being
connected to a serial switching device. The following combinations involving the
Series 1400a Monitor can be supported at this time:

Series 1400a and a Model 2025

Series 1400a and a Series 5400 Monitor

Although RPComm supports both the Series 1400a and the Model 2000-FRM
monitors, it is not possible to connect these instruments to a single serial switching
device. This is because the Series 1400a Monitor requires the local communication
flow control to be set to “RTS/CTS” and the Model 2000-FRM sampler does not
support any local communication flow control.

If a Series 1400a and a Model 2000-FRM are located at the same site, two modems
and phone lines are necessary for communication with the two instruments.

H.3.2.1. CONNECTING A SERIES 1400A MONITOR AND O THER R&P I NSTRUMENTS

OF DIFFERENT MODELS

Follow these steps to connect a Series 1400a Monitor and another R&P
instrument via a serial switching device:

1) Set up the Series 1400a Monitor and the other instrument for
direct communications (Section 10).
2) Create a new connection to each instrument according to Section
10.2.2 and verify that the units are communicating properly.
NOTE: If the connection is successful, the unit’s serial number will be displayed
at the top of the screen. If the connection is not successful or if there is no unit
attached, then the serial number will be blank or will display “99999.”
3) Once the RPComm software and instrument configurations have
been verified, disconnect the direct connection.
4) Connect your computer directly to the modem that will be con-
nected to the serial switching device (follow the modem’s
instruction manual).

Appendix J: Original Design Mass Flow Controllers

This appendix describes the maintenance and verification procedures for the Original
Design Mass Flow Controllers of the Series 1400a Monitor.

As of February 2001, R&P began manufacturing the Series 1400a Monitor with newly
designed mass flow controllers (“Second-Generation Flow Controller Design”) in the
control unit. If you purchased your Series 1400a Monitor before February 2001, or if
the serial number on your monitor is 140AB234170011 or below, your control unit
has the original version mass flow controllers. If you purchased a monitor with the
original mass flow controller design, follow the instructions in this section. If your
monitor has the “Second-Generation” mass flow controllers installed, refer to the
Service Manual. Also, if you purchased the Flow Controller Upgrade Kit (55-7758)
and installed the Second-Generation mass flow controllers in your Series 1400a
Monitor, refer to the Service Manual.

R&P recommends that the user perform the analog calibration (Service Manual)
before performing the mass flow controller (MFC) calibrations. Note that the
procedures set forth in this section specify the use of a volumetric flow meter. If a non-
volumetric flow meter (such as a mass flow meter) is used, you must convert the flow
meter’s indicated flow rate to a volumetric flow rate using the local temperature and
pressure conditions at the flow meter.

J.1. OVERVIEW OF CALIBRATION PROCEDURES

Calibration Procedures Interval Reference

Mass flow controller calibration (software) 6 months Section J.2
Mass flow controller calibration (hardware) 1 year Section J.3

The calibration intervals provided above are guidelines. Requirements for routine
calibration are site-specific, and may be better defined by the user as necessary.

APPENDIX J: ORIGINAL DESIGN MASS FLOW CONTROLLERS PAGE J-1

 Revision B.000

Operating Manual, TEOM Series 1400a Ambient Particulate (PM-10) Monitor

J.2. FLOW CONTROLLER CALIBRATION — SOFTWARE

The software procedure allows the user to calibrate the sample and bypass flow rates
without having to adjust any hardware.

Items Needed:
Reference flow meter such as a bubble meter, dry gas meter, or mass
flow meter.
NOTE: This reference flow meter should have been recently
calibrated to a primary standard, and should have an accuracy of 1%
at 3 l/min.

Follow the steps below to perform a software calibration of the original

design mass flow controllers:

1) Turn off the control unit.

2) Disconnect the electric cable that links the control unit with the
sensor unit.
3) Remove the main and bypass flow lines from their connections
on the back panel of the control unit.
4) Turn on the control unit, and make sure that the pump is on.
5) When in the Main screen (Figure J-1), press the <STEP SCREEN>

“T-A/S” (average/standard temperature) and “P-A/S” (average/
standard pressure) display on the screen. Record the set points
for the average temperature (located on the left-hand side of this
field), and the average pressure (located on the left-hand side of
this field).
9) Ensure that the monitor is in the Setup Mode (Section 6).
10) On the monitor, set the average temperature and average pres-
sure parameters to the current local conditions.
NOTE: The average pressure reading should be actual pressure NOT corrected
to sea level.
IMPORTANT: The average temperature and pressure settings should not read
99°° C and 9 atm (respectively) during a mass flow controller calibration.
11) On the flow meter, set the average temperature and average
pressure parameters to the current local conditions.

12) Press the up and down arrow keys to position the screen so that
“FAdj Main” and “FAdj Aux” display on the screen.
13) Connect a reference flow meter such as a bubble meter, dry gas
meter, or mass flow meter to the port labelled “SENSOR FLOW”
on the back panel of the control unit. This reference flow meter
should have been recently calibrated to a primary standard, and
should have an accuracy of 1% at 3 l/min.
14) Compare the monitor’s “F-Main” set point (step 10) above with
the flow rate indicated by the flow meter. The “F-Main” reading is
in volumetric liters per minute. If you are using a mass flow
meter, you must adjust its reading for temperature and pressure
to obtain volumetric flow under the test conditions. If you are
using a volumetric flow meter, you do not need to adjust your
flow meter for temperature and pressure. If the “F-Main” set point
(step 10) matches the flow rate indicated by the flow meter, go to
step 16. If the “F-Main” set point (step 10) does not match the
flow rate indicated by the flow meter, go to step 15.
15) Edit the “FAdj Main” field on the monitor so that the volumetric
flow rate indicated by the flow meter matches the “F-Main” set
point (step 10). The value for “FAdj Main” can be increased and
decreased by pressing the up and down keys when in the Edit
Mode (Section 4). If you must enter a step adjustment greater
than ±10% to calibrate the mass flow controller, you must per-
form a hardware calibration (Section J.3).
16) If your system has an auxiliary flow controller, repeat steps 8 to
14, replacing the references to “F-Main” and “FAdj Main” with “F-
Aux” and “FAdj Aux.” Connect the reference flow meter to the
“BYPASS FLOW” port located on the back panel of the control
unit.
17) Change the average temperature (located on the left-hand side of
this field) and the average pressure (located on the left-hand side
of this field) readings back to their original values (step 8).
18) Turn off the control unit.
19) Install the main and bypass flow lines onto the back panel of the
control unit (Section 2).
20) Connect the electric cable that links the control unit with the
sensor unit.
21) Turn on the control unit, and make sure that the pump is on.
22) Perform a system leak check (Section 3).

Appendix L: TEOMCOMM Software

TEOMCOMM is a communications software package developed by R&P to provide

interactive remote communication with the Series 1400a Monitor. The user can use
this software application to download data stored in the instrument, and retrieve and
set instrument operating parameters remotely.

TEOMCOMM has two communication modes — direct and modem. Direct commu-
nication is accomplished when the unit has a direct cable connection with a personal
computer (PC). Modem communication is accomplished when the unit has a connec-
tion with a PC through the use of a modem and phone line (Appendix H). Before
modem communication is attempted, direct communication must be successfully
completed. This will ensure that the PC and unit have been set up properly for
communications.
