 UltraRAE 3000 User’s Guide

2. Insert four fresh AA batteries as indicated by the polarity (+/-)

markings.

3. Replace the cover. Replace the three screws.

IMPORTANT!
Alkaline batteries cannot be recharged. The instrument’s internal
circuit detects alkaline batteries and will not allow recharging. If you
place the instrument in its Travel Charger or Charger Stand, the
alkaline battery will not be recharged. The internal charging circuit is
designed to prevent damage to alkaline batteries and the charging
circuit when alkaline batteries are installed inside the instrument. If
you try to charge an alkaline batteries installed in the instrument, the
Charging Cradle or Travel Charger’s charging LED does not glow,
indicating that it will not charge the alkaline batteries.

Note: When replacing alkaline batteries, dispose of old ones properly.

6 Charging A Lithium-Ion Battery

Always fully charge the battery before using the instrument. The
instrument’s Li-ion battery is charged by attaching the instrument to
the Travel Charger (or by placing the instrument in the optional
Charger Stand). Contacts on the bottom of the instrument meet the
Travel Charger’s (or Charger Stand’s) contacts, transferring power
without other connections.

Travel
Charger

Charger Stand

Note: Before connecting the charger to the instrument, visually

inspect the contacts to make sure they are clean. If they are not, wipe
them with a soft cloth. Do not use solvents or cleaners.

Follow this procedure to charge the instrument:

1. Plug the AC/DC adapter’s barrel connector into the
instrument’s Charger Stand or Travel Charger.

2. Plug the AC/DC adapter into the wall outlet.

3. Connect the AC/DC adapter to the Travel Charger (or
Charger Stand).

16

Downloaded from www.Manualslib.com manuals search engine

 UltraRAE 3000 User’s Guide

4. Place the instrument into the Travel Charger or Charger Stand.

The LED in the Travel Charger (or Charger Stand) should
glow.

The instrument begins charging automatically. (If the optional

Charger Stand is used, the “Primary” LED blinks green to
indicate charging.) During charging, the diagonal lines in the
battery icon on the instrument’s display are animated and you see the
message “Charging...”

Note: If the Li-ion battery has been discharged below a certain

threshold, the “Charging...” message does not display immediately.
The charging LED blinks to indicate that it is charging, and after it
has been charging for a while, the “Charging...” message appears.

When the instrument’s battery is fully charged, the battery icon is no

longer animated and shows a full battery. The message “Fully
charged!” is shown. (If the Charger Stand or Travel Charger is used,
its LED glows continuously green.)

Note: If you see the “Battery Charging Error” icon (a battery

outline with an exclamation mark inside), check that the
instrument or rechargeable battery has been properly set into
the Travel Charger (or Charger Stand). If you still receive the
message, check the Troubleshooting section of this guide.

Note: If the instrument or battery has been charging for more than 10
hours and you see the “Battery Charging Error” icon and a message
that says, “Charging Too Long,” this indicates that the battery is not
reaching a full charge. Try changing the battery and make sure the
contacts on the instrument are meeting the Travel Charger’s (or
Charger Stand’s) contacts. If the message is still shown, consult your
distributor or RAE Systems Technical Services.

6.1 Charging A Spare Rechargeable Battery

(Optional Charger Stand Only)

A rechargeable Li-ion battery can be charged when it is not inside the

monitor. The Charger Stand is designed to accommodate both types
of charging. Contacts on the bottom of the battery meet the contacts
on the Charger Stand, transferring power without other connections,
and a spring-loaded capture holds the battery in place during
charging.

1. Plug the AC/DC adapter into the Charger Stand.

2. Place the battery into the Charger Stand, with the gold-plated
contacts on top of the six matching charging pins.
3. Plug the AC/DC adapter into the wall outlet.

The battery begins charging automatically. During charging, the

Secondary LED in the Charger Stand blinks green. When charging is
complete, it glows steady green.

Release the battery from the Charger Stand by pulling it back toward
the rear of the Charger Stand and tilting it out of its slot.

Note: If you need to replace the Li-ion battery pack, replacements are
available from RAE Systems. The part number is 059-3051-000.

WARNING!
To reduce the risk of ignition of hazardous atmospheres, recharge
and replace batteries only in areas known to be non-hazardous.

6.2 Low Voltage Warning

When the battery’s charge falls below a preset voltage, the
instrument warns you by beeping once and flashing once every
minute, and the “empty battery” icon blinks on and off once
per second. You should turn off the instrument within 10
minutes and either recharge the battery by placing the

18

Downloaded from www.Manualslib.com manuals search engine

 UltraRAE 3000 User’s Guide

instrument in its cradle, or replace the battery with a fresh one with a
full charge.

6.3 Clock Battery

An internal clock battery is mounted on one of the instrument’s
printed circuit boards. This long-life battery keeps settings in memory
from being lost whenever the Li-ion battery or alkaline batteries are
removed. This backup battery should last approximately five years,
and must be replaced by an authorized RAE Systems service
technician. It is not user-replaceable.

6.4 Data Protection While Power Is Off

When the instrument is turned off, all the current real-time data
including last measured values are erased. However, the datalog data
is preserved in non-volatile memory. Even if the battery is
disconnected, the datalog data will not be lost.

8 Operating The Instrument

The instrument is designed as a broadband VOC gas monitor and
datalogger for work in hazardous environments. It gives real-time
measurements and activates alarm signals whenever the exposure
exceeds preset limits. Prior to factory shipment, the instrument is
preset with default alarm limits and the sensor is pre-calibrated with
standard calibration gas. However, you should test the instrument and
verify the calibration before the first use. After the instrument is fully
charged and calibrated, it is ready for immediate operation.

8.1 Turning The Instrument On (Simple)

1. With the instrument turned off, press and hold [MODE].

2. When the display turns on, release the [MODE] key.

The RAE Systems logo should appear first. (If the logo does not
appear, there is likely a problem and you should contact your
distributor or RAE Systems Technical Support.) The instrument is
now operating and performs self tests. If any tests (including sensor
and memory tests) fail, refer to the Troubleshooting section of this
guide.

Once the startup procedure is complete, the instrument shows a

numerical reading screen with icons. This indicates that the
instrument is fully functional and ready to use.

9 Operating Modes
The UltraRAE is actually two monitors in one:

• Compound-specific monitor
• VOC monitor

As a compound-specific monitor, it takes timed measurements and

uses a separation tube in conjunction with software that enables the
UltraRAE 3000 to give specific readings on one particular type of
compound, such as benzene or butadiene.

As a VOC monitor, the UltraRAE 3000 operates in different modes.

In some cases, you can change modes using a password and using the
instrument’s navigation. In other cases, you must use ProRAE Studio
software.

The following two sections cover operation in the two modes.

• Compound Specific, 31.

• VOC, page 38.

The diagram on the next page shows the basic flow of the UltraRAE
3000’s functions. The area with the gray field is the compound-
specific (tube) mode, while the rest shows VOC mode. Navigate
through the steps by using the [Y/+] and [N/-] keys as shown in the
diagram.

Note: If you use a password to access Programming Mode (see page

60), then the navigation changes slightly, entering part of Advanced
Hygiene Mode’s settings, as shown on page 29.

10 Compound-Specific Operation

10.1 Compound-Specific Measurement

The UltraRAE 3000 can perform compound-specific measurement in
addition to general VOC measurement. This requires using a RAE-
Sep separation tube (butadiene or benzene) and having the UltraRAE
3000 in Tube Mode, operating with a 9.8eV lamp.

10.2 Measurement Phases

To perform a compound-specific measurement, follow this order:

1. UltraRAE 3000 is ready for sampling

2. Prepare the separation tube
3. Insert the separation tube
4. Start measurement
5. UltraRAE 3000 displays and logs measurement
6. Remove the separation tube

10.3 Performing A Measurement

Before performing a compound-specific measurement for Benzene or
Butadiene using a RAE-Sep separation tube, make sure the UltraRAE
3000 is in Tube Mode and that the appropriate tube type is selected.
The UltraRAE 3000 only acts as a compound-specific measurement
device when it is equipped with a 9.8eV lamp. The UltraRAE 3000 is
designed to auto-sense the lamp type. It can also be manually set to
default to a 9.8eV lamp type.

Make sure the UltraRAE 3000 is set to operate with your selected tube:

1. Enter Programming Mode.

2. Select Measurement.
3. Select Tube Selection.
4. Make a choice of Benzene or Butadiene.
5. Save your choice.

13 Integrated Sampling Pump

The instrument includes an integrated sampling pump. This
diaphragm-type pump that provides a 450 to 550 cc per minute flow
rate. Connecting a Teflon or metal tubing with 1/8" inside diameter to
the gas inlet port of the instrument, this pump can pull in air samples
from 200' (61 m) away horizontally, or 90' (27.5 m) vertically, at
about 3' (0.9 m) per second flow speed.
Note: In Search Mode, the pump turns on when a sample
measurement is started, and turns off when the sample is manually
stopped.
If liquid or other objects are pulled into the inlet port filter, the
instrument detects the obstruction and immediately shuts down the
pump. The alarm is activated and a flashing pump icon is displayed.
You should acknowledge the pump shutoff condition by clearing the
obstruction and pressing the [Y/+] key while in the main reading
display to restart the pump.

14 Backlight
The LCD display is equipped with an LED backlight to assist in
reading the display under poor lighting conditions.

15 Datalogging
During datalogging, the instrument displays a disk icon to indicate
that datalogging is enabled. The instrument stores the measured gas
concentration at the end of every sample period (when data logging is
enabled). In addition, the following information is stored: user ID,
site ID, serial number, last calibration date, and alarm limits. All data
are retained (even after the unit is turned off) in non-volatile memory
so that it can be down- loaded at a later time to a PC.
15.1 Datalogging Event
When Datalogging is enabled, measurement readings are being saved.
These data are stored in “groups” or “events.” A new event is created
and stored each time the instrument is turned on and is set to
automatic datalogging, or a configuration parameter is changed, or
datalogging is interrupted. The maximum time for one event is 24
hours or 28,800 points. If an event exceeds 24 hours, a new event is
automatically created. Information, such as start time, user ID, site
ID, gas name, serial number, last calibration date, and alarm limits are
recorded.
15.2 Datalogging Sample
After an event is recorded, the unit records a shorter form of the data.
When transferred to a PC running ProRAE Studio, this data is
arranged with a sample number, time, date, gas concentration, and
other related information.

17 Standard Kit & Accessories

17.1 AC Adapter (Battery Charger)

WARNING
To reduce the risk of ignition of hazardous atmospheres, recharge
battery only in area known to be non-hazardous. Remove and
replace battery only in area known to be non-hazardous.
Ne charger les batteries que dans emplacements designés non-
dangereuses.
A battery charging circuit is built into the instrument cradle. It only needs a
regular AC to 12 VDC adapter (wall-mount transformer, part number 500-
0114-000) to charge the instrument.
To charge the battery inside the instrument:
1. Power off the instrument.
2. Connect the AC adapter to the DC jack on the instrument’s cradle.
If the instrument is off, it automatically turns on.
3. While charging, the display message shows “Charging.” The
Primary LED on the cradle flashes green when charging.
4. When the battery is fully charged, the LED changes to glowing
green continuously, and the message “Fully charged” appears on
the display. If there is a charging error, the LED glows red
continuously.
A completely discharged instrument can be charged to full capacity
within 8 hours. Batteries drain slowly even if an instrument is off.
Therefore, if the instrument has been in storage or has not been
charged for several days or longer, check the charge before using it.
The factory-supplied battery is designed to last for 16 hours of normal
operation (no alarm), for a new battery under the optimum
circumstances. As the battery becomes older or is subject to adverse
conditions (such as cold ambient temperature), its capacity will be
significantly reduced.

tubing with a metal adapter on one end. During calibration, simply
insert the metal adapter into the regular gas inlet probe of the
instrument and the tubing to the gas regulator on the gas bottle.
18.2 Calibration Regulator
The Calibration Regulator is used in the calibration process. It
regulates the gas flow rate from the Span gas cylinder into the gas
inlet of the instrument during calibration process. The maximum flow
rate allowed by the flow controller is about 0.5L/min (500 cc per
min.). Alternatively, a demand-flow regulator or a Tedlar gas bag
may be used to match the pump flow precisely.
18.3 Organic Vapor Zeroing Kit
The Organic Vapor Zeroing Kit is used for filtering organic air
contaminants that may affect the zero calibration reading. To use the
Organic Vapor Zeroing Kit, simply connect the filter to the inlet port
of the instrument.

19.2 Zero (Fresh Air) Calibration

This procedure determines the zero point of the sensor calibration

curve. To perform a fresh air calibration, use the calibration adapter to
connect the instrument to a “fresh” air source such as from a cylinder
or Tedlar bag (optional accessory). The “fresh” air is clean, dry air
without organic impurities and an oxygen value of 20.9%. If such an
air cylinder is not available, any clean ambient air without detectable
contaminants or a charcoal filter can be used.
At the Zero Calibration menu, you can proceed to perform a Zero
calibration or bypass Zero calibration and perform a Span calibration.
You may also go back to the initial Calibration menu if you want to
exit calibration.

• Press [Y/+] to start calibration.

• Press [MODE] to quit and return to the main calibration
display.

If you have pressed [Y/+] to enter Zero calibration, then you will see
this message:

1. Turn on your Zero calibration gas.

2. Press [Y/+] to start calibration.

Note: At this point, you may press [MODE] if you decide

that you do not want to initiate calibration. This will take you
directly to the Calibration menu, highlighted for Span

19.3 Span Calibration

This procedure determines the second point of the sensor calibration
curve for the sensor. A cylinder of standard reference gas (span gas)
fitted with a 500 cc/min. flow-limiting regulator or a flow-matching
regulator is the simplest way to perform this procedure. Choose the
500 cc/min. regulator only if the flow rate matches or slightly exceeds
the flow rate of the instrument pump. Alternatively, the span gas can
first be filled into a Tedlar bag or delivered through a demand-flow
regulator. Connect the calibration adapter to the inlet port of the
instrument, and connect the tubing to the regulator or Tedlar bag.
Another alternative is to use a regulator with >500 cc/min flow but
allow the excess flow to escape through a T or an open tube. In the
latter method, the span gas flows out through an open tube slightly
wider than the probe, and the probe is inserted into the calibration
tube.

20 Three-Point Calibration
For enhanced accuracy, it is possible to perform a second Span
calibration in addition to the Zero and Span calibrations outlined in
the previous section. Your instrument first must be set to allow this
third calibration. This requires using ProRAE Studio software and a
PC, as well as a higher concentration of calibration gas.

Note: Once the third calibration is set, you do not need to use
ProRAE Studio to allow future 3-point calibrations. Also, you can
only disable 3-point calibration capability by using ProRAE Studio
again.

Perform the Zero and Span calibrations. After the first Span
calibration (Span 1) is completed, the display a second Span
calibration (Span 2) can be performed. The process is identical to the

20.1 Span 2 Calibration

A cylinder of standard reference gas (span gas) fitted with a 500
cc/min. flow-limiting regulator or a flow-matching regulator is the
simplest way to perform this procedure.

Note: This gas should be of a higher concentration than the gas used
for Span 1 calibration.

Choose the 500 cc/min. regulator only if the flow rate matches or
slightly exceeds the flow rate of the instrument pump. Alternatively,
the span gas can first be filled into a Tedlar bag or delivered through a
demand-flow regulator. Connect the calibration adapter to the inlet
port of the instrument, and connect the tubing to the regulator or
Tedlar bag.
Another alternative is to use a regulator with >500 cc/min flow but
allow the excess flow to escape through a T or an open tube. In the
latter method, the span gas flows out through an open tube slightly
wider than the probe, and the probe is inserted into the calibration
tube.

22.4.1 Meas. Gas

Measurement gases are organized in four lists:

• My List is a customized list of gases that you create. It contains a

maximum of 10 gases and can only be built in ProRAE Studio on
a PC and transferred to the instrument. Note: The first gas in the
list is always isobutylene (it cannot be removed from the list).
• Last Ten is a list of the last ten gases used by your instrument.
The list is built automatically and is only updated if the gas
selected from Custom Gases or Library is not already in the Last
Ten. This ensures that there is no repetition.
• Gas Library is a library that consists of many of the gases found
in RAE Systems’ Technical Note TN-106 (available online at
www.raesystems.com).
• Custom Gases are gases with user-modified parameters. Using
ProRAE Studio, all parameters defining a gas can be modified,
including the name, span value(s), correction factor, and default
alarm limits.

The pump’s duty cycle is the ratio of its on time to off time. The duty
cycle ranges from 50% to 100% (always on; this is the default value),
and the period is 10 seconds. Therefore, a duty cycle of 60% means that
the pump is on for 6 seconds and off for four seconds. Duty cycling is
employed by the instrument to clean the PID. A lower duty cycle has a
greater effect on keeping the PID clean than a higher duty cycle.

Important! Pump duty cycling is interrupted when the instrument

senses a gas. The pump’s duty cycle is disabled when the
measurement is greater than the 2ppm threshold and is re-enabled
when the reading falls below 90% of the threshold (1.8 ppm).

25.4.2 Adjusting The Pump Stall Threshold

If the gas inlet is blocked but the pump does not shut down, or the
pump shuts down too easily with a slight blockage, the pump stall
threshold value may be set too high or too low.

Use the following steps to adjust the pump stall threshold:

25.4.3 Pump High

In Diagnostic Mode, press the [MODE] key until “Pump High” is
displayed. The display shows the maximum, minimum, and stall
values for the pump at its high speed. Write down the “Max” reading.

Block the gas inlet and watch the pump current reading (labeled “I”)
increase. Write down its blocked reading. Note: If the pump current
reading does not increase significantly (less than 10 counts), then
there may be a leak in the gas inlet or the pump is weak or defective.

Add the two readings you wrote down. This is the average of the
maximum block count and the maximum idle count. Divide that
number by 2. Use the [Y/+] or [N/-] key to increase or decrease the
stall value to equal that number.

Press the [MODE] key to exit this display.

25.4.4 Pump Low

5. Cover the cup with your hand.

25° C / 77° F

6. Wait a few seconds and check the high-humidity reading.

7. The humidity reading should be within ±10% of the 100%
humidity reading. If it is not, then the THP Sensor (part number
023-3011-000-FRU) should be replaced.
8. Check the low-humidity reading by connecting the inlet probe to
a tank of zero gas (air at 0% humidity).
9. Turn on the zero gas and wait a few seconds for the sensor
reading to stabilize. It should read within 10% of the low-
reference number. If it does not, replace the T.H.P. sensor.

27.3 Cleaning The PID Sensor

Place the entire PID sensor module into GC grade methanol. It is
highly recommended that an ultrasound bath to be used to clean the
sensor for at least 15 minutes. Then dry the sensor thoroughly. Never
touch the electrodes of the sensor by hand.
Also use a methanol-soaked cotton swab to wipe off the lamp housing
where it contacts the sensor when the sensor is installed.
Turn over the sensor so that the pins point up and the sensor cavity is
visible. Examine the sensor electrodes for any corrosion, damage, or
bending out of alignment. The metal sensor electrode “fingers”
should be flat and straight. If necessary, carefully bend the sensor
fingers to ensure that they do not touch the Teflon portions and that
they are parallel to each other. Make sure that the nuts on the sensor
pins are snug but not overtight. If the sensor is corroded or otherwise
damaged, it should be replaced.

27.3.1 Cleaning The Lamp Housing Or Changing The

Lamp
If the lamp does not turn on, the instrument will display an error
message to indicate replacement of the lamp may be required.
1. If the lamp is operational, clean the lamp window surface and the
lamp housing by wiping it with GC grade methanol using a cotton
swab using moderate pressure. After cleaning, hold the lamp up
to the light at an angle to detect any remaining film. Repeat the
process until the lamp window is clean. Never use water solutions
to clean the lamp. Dry the lamp and the lamp housing thoroughly
after cleaning.
CAUTION: Never touch the window surface with the fingers
or anything else that may leave a film. Never use acetone or
aqueous solutions.
2. If the lamp does not turn on, remove the lamp from the lamp
housing. Place the lamp O-ring onto the new lamp. Insert the new
lamp, avoiding contact with the flat window surface.
3. Reinstall the PID sensor module.
4. Tighten the Lamp Housing Cap.

Alarm Signals
During each measurement period, the gas concentration is compared
with the programmed alarm limits (gas concentration alarm limit
settings). If the concentration exceeds any of the preset limits, the
loud buzzer and red flashing LED are activated immediately to warn
you of the alarm condition.
In addition, the instrument alarms if one of the following conditions
occurs: battery voltage falls below a preset voltage level, failure of
the UV lamp, pump stall, or when the datalog memory is full.

Charging The Battery

Always fully charge the battery before using the instrument. The
instrument’s Li-ion/NiMH battery is charged by placing the
instrument in its cradle. Contacts on the bottom of the instrument
meet the cradle’s contacts, transferring power without other
connections.

Note: Before setting the instrument into its charging cradle, visually
inspect the contacts to make sure they are clean. If they are not, wipe
them with a soft cloth. Do not use solvents or cleaners.

Follow this procedure to charge the instrument:

1. Plug the AC/DC adapter’s barrel connector into the

instrument’s cradle.

2. Plug the AC/DC adapter into the wall outlet.

3. Place the instrument into the cradle, press down, and lean it
back. It locks in place and the LED in the cradle glows.

Note: To release the instrument, press down and tilt the top out
of the cradle and lift up.

The instrument begins charging automatically. The LED on the front

of the cradle marked “Primary” blinks during charging. During
charging, the diagonal lines in the battery icon on the instrument’s
display are animated and you see the message “Charging...”

When the instrument’s battery is fully charged, the battery icon is no

longer animated and shows a full battery. The message “Fully
charged!” is shown and the Primary LED on the cradle glows
continuously green.

 UltraRAE 3000 User’s Guide

Note: A spare Li-ion battery (059-3051-000) or NiMH (059-3054-

000) can be charged by placing it directly in the charging port on the
back of the cradle. It can be charged at the same time as the
instrument. Press the battery in place, sliding it slightly toward the
front of the cradle. This locks it in the cradle. To release the battery,
slide it forward again and tilt it up.

Note: An Alkaline Battery Adapter (part number 059-3052-000),

which uses four AA alkaline batteries (Duracell MN1500), may be
substituted for the Li-Ion battery.

WARNING!
To reduce the risk of ignition of hazardous atmospheres, recharge
and replace batteries only in areas known to be non-hazardous.
Remove and replace batteries only in areas known to be non-
hazardous.

Low Voltage Warning

When the battery’s charge falls below a preset voltage, the instrument
warns you by beeping once and flashing once every minute, and the
battery icon blinks once per second. You should turn off the
instrument within 10 minutes and either recharge the battery by
placing the instrument in its cradle, or replace the battery with a fresh
one with a full charge.

Clock Battery
An internal clock battery is mounted on one of the instrument’s
printed circuit boards. This long-life battery keeps settings in memory
from being lost whenever the Li-ion, NiMH, or alkaline batteries are
removed. This backup battery should last approximately five years,
and must be replaced by an authorized RAE Systems service
technician. It is not user-replaceable.
