 BATTERY INSTALLATION AND REMOVAL
Either dosimeter will function as a Personal Noise Dosimeter, an Environmental Monitor, or an Event Monitor. The Q400
provides Type 2 measurement accuracy, while the Q500 is a precision Type 1 instrument. The battery must be a 9 Volt alkaline type.
(Examples are: NEDA 1604A, IEC 6LF22, or IEC 6LR61)
# When used as a Personal Noise Dosimeter: # Replace the battery as follows (see Figure 2):
The dosimeter may be clipped on a belt or worn in a shirt pocket. The small microphone is simply clipped 1.) Remove the battery cover.
to the shirt or shirt collar near the ear.
2.) Lift the non-terminal end of the battery out of the battery compartment.
# When used as an Environmental Monitor or Events Monitor: 3.) Remove the battery.

The dosimeter may be either hand held or mounted to a standard camera tripod. The microphone is 4.) Notice the battery orientation drawing on the battery cover. Be sure that the battery is properly oriented

extreme accuracy and detail.
Note: Battery life is affected by the dosimeter measuring setup parameters. Refer to the specifications for details.
# When used with a Printer:
The dosimeter can print detailed reports of noise events. It connects to a printer by using a Quest "Parallel
Printer Interface" or "Serial Computer Interface".

The dosimeter can function as two simultaneously operating noise dosimeters. When this is done, each is programmed
with a different set-up. The dosimeter can also be programmed to perform the C - A measurement.

Figure 2. Battery Installation and Removal.

An internal battery powers the clock and memory. When this battery's voltage gets low, data memory and setup will not be
retained when a 9V battery is not in the dosimeter. The memory only draws current from this battery when a 9V battery is
not in the unit. Contact the factory or a Quest service center for replacement.

Acoustically Calibrate the dosimeter as follows:

1.) Turn the dosimeter On.

2.) Press the CAL Key. "PRE-SURVEY" will be highlighted.

3.) Press the ENTER Key. "CALIBRATOR" will appear.

4.) Use the UP ARROW and DOWN ARROW Keys to set the number to match the output level listed on the
acoustic calibrator.

5.) Turn on the calibrator (1000 Hz). Listen to see that the
calibrator is producing a tone. If no tone is present,
see the calibrator manual to correct the problem.
6.) Insert the Microphone and Adapter into the Calibrator.

7.) Press the ENTER Key.

8.) "CALIBRATING..." will appear for a moment with "..." slowly moving left to right. This means that the
system is attempting to calibrate.
# If "BAD CALIBRATION / TO TRY AGAIN / PRESS (CAL)" appears or the SPL does not match the
entered calibrator level by +/- 0.1 dB:

double for every 3dB decrease in level, so for practical situations encountered in the field the limitations should not be a

PRINCIPLES OF OPERATION Microphone Characteristics

The Q-400 Noise Dosimeter uses an 8 mm omnidirectional ceramic microphone. It is buffered by a high impedance FET
General Characteristics input stage. (See Figure 16.)
The Q-400 and Q-500 dosimeters use low power state-of-the-art circuitry. Each dosimeter is very stable and reliable over a
wide range of environmental conditions.

The low power circuitry gives each dosimeter a long battery life. When the 9 volt battery is changed, all dosimeter
information is retained due to an internal lithium battery. The lithium battery lasts for many years before needing
replacement. (See SPECIFICATIONS)
A rubberized Key Pad is used for all data entry and settings. Menus appear on the display and the keys are used to enter
changes.
A block diagram of the Q-400 and Q-500, is shown in Figure 15.

Figure 16. Q-400 Microphone Frequency Response.

The Q-500 Noise Dosimeter uses a 1/2-inch free field prepolarized condenser (electret) microphone. It is buffered by a high
impedance FET preamp. (See Figure 17.)

Weighting Characteristics TYPICAL OPERATING PROCEDURE

The Q-400 and Q-500 both have "A" and "C" weighting characteristics as shown in Figure 18. For most industrial and
community noise measurement requirements, the "A" weighting should be used. The "A" weighting has a response similar As a Personal Noise Dosimeter
to the human ear. The "C" weighting is used for measuring noise reduction in hearing protectors and other scientific
purposes. 1.) Check all dosimeter setups that are relevent to the measurement. Change where needed. See DETAILED

As a Survey Event Monitor ACCURACY

Up to 999 different Events can be stored.

For maximum accuracy, it is important to use the dosimeter correctly and to understand its limitations.
1.) Check all dosimeter setups that are relevent to the measurement. Change where needed. See DETAILED
OPERATING INSTRUCTIONS if necessary. It will correctly integrate all sound levels within the range of the instrument.

2.) Reset the dosimeter. A few items related to accuracy are as follows:

MENU ON/OFF Key

"RESET-5" Low Level Measurements

3.) Perform a Pre-Survey Calibration of the dosimeter. The effect of the "Noise Floor" on low level readings can cause inaccurate data.

CAL Key In a "Perfectly Quiet" room, the "Noise Floor" produced by the microphone is approximately:
"PRE-SURVEY"
# 35 dB on "A" Weighting.
4.) Connect the Microphone Boom to the dosimeter. # 45 dB on "C" Weighting.
5.) Wrap the cable neatly around the Boom and connect the microphone to the top of the Boom. Measurements must always be at least 5 dB above the "Noise Floor". to be valid. Therefore, the lowest possible
measurements of the dosimeter are approximately:
6.) For the best accuracy, point the microphone as follows:
# 40 dB on "A" Weighting (Lowest Valid Reading).
# Q-400 Upward forming approximately a 70 degree angle with the noise source.
# 50 dB on "C" Weighting (Lowest Valid Reading).
# Q-500 Directly at the noise source.
7.) Press the EVENT Key to monitor the event number. Accuracy of Readings
(Cev = Current Event Number)
There is a tendency to overestimate the accuracy of digital readings.
8.) Use the RUN/PAUSE Key to Run and then Pause the dosimeter at each event location as needed.
The values (such as Leq) are computed to a precision of 0.1 dB. However, the absolute accuracy of the reading is not 0.1
1st Location: "Cev" will be "1". dB, but is accurate to the stated overall accuracy of the instrument.
2nd Location: "Cev" will be "2". The 0.1 dB resolution is useful in determining the minimum sample time required to get an accurate short term
etc. measurement.

Be sure that a representative sample of noise in each location has been accumulated. # If, for example, the Leq is increasing 0.3 dB every second, then a longer sample time is required.

See USING THE EVENT MODES for details on how to use Events. # If the Leq is remaining stable from second to second within a few tenths of a dB, then the sample time is
long enough.

Microphone Positioning Microphone Windscreen

The dosimeter measures sound most accurately without the presence of sound reflecting or absorbing objects. It is recommended that a windscreen be used at all times. The Q-400 uses the WS-5 Windscreen and the Q-500 uses the
WS-7 Windscreen. Using a windscreen will improve the accuracy by minimizing the effect of the following:
Any near-by object or surface (including the operator) will act as a reflector or absorber of sound.
# Wind blowing across the microphone can produce higher than normal sound level readings.
To minimize these errors, use the dosimeter as follows:
# The windscreen blocks wind from direct contact with the microphone, producing less unwanted
# When taking Hand-Held measurements: noise.
# Connect the Microphone Boom. (See USING THE MICROPHONE BOOM.) # Clothing brushing against the microphone can produce higher than normal sound level readings.
# Hold the dosimeter with your arm extended and point the microphone as follows: # The windscreen helps position the microphone so that clothing cannot brush against it as easily.
# Q-400 Upward forming approximately a 70 degree angle with the noise source. # Dirt entering the microphone, in time, can damage the microphone, possibly changing the microphone's
frequency characteristics.
# Q-500 Directly at the noise source.
# The windscreen catches and collects this dirt before it enters the microphone.
# When taking Tripod-Held measurements:
Simply insert the microphone into the windscreen and gently pull it over the Velcro strip.
# Connect the Microphone Boom. (See USING THE MICROPHONE BOOM.)
TROUBLESHOOTING
# Mount the dosimeter to the tripod mount (located on the belt clip) with the microphone pointed as follows:
# Q-400 Upward forming approximately a 70 degree angle with the noise source. Blank display when the ON/OFF Key is pressed:
# Q-500 Directly at the noise source. # Replace the battery with a known fresh battery.

away from the neck if possible.
# Check the Calibrator; Listen for a tone from its output.
# If the noise seems to be coming from one location, place the microphone near the ear facing that location.
# Reset the dosimeter and try again.
# Install a Windscreen on the microphone. It helps to do the following:
# Try a different microphone if you have another dosimeter. If this works, the microphone needs replacing.
# holds the microphone in an upright position.
# Return for service.
# keeps the microphone from brushing against clothing. This can produce higher than normal noise

EXP: Units: Pascal Squared Hours (Pa2H)
Definitions Exposure
It is a method of measuring dosage. Pa2H is a linear unit rather than a percentage.
All definitions are in reference to the way that they are used with either the Q-400 or Q-500 dosimeter.
1 Pascal is equal to 94 dB. 94 dB for 1 Hour equals 1 Pa2H.

It is the average sound pressure during a 24 hour calendar day. However, all sound pressures between the hours SLOW: Units: Time (seconds)
of 10 pm and 7 am (2200 to 0700 hours) are increased by 10 dB before being averaged. Unless otherwise stated, Slow Response
A-Weighting should be used and is generally assumed. A Time Constant of 1 second. When Slow is used, a fluctuating noise into the dosimeter will cause SPL to operate
in a much slowed-down fashion.
The dosimeter will only measure LDN when programmed to do so. It automatically will program itself to the 3 dB
Exchange Rate since LDN is not defined for other Exchange Rates. W444444444444444444444444444444444444444444444444444444444444444U

TWA (Prt): Units: decibels (dB)
Projected Time Weighted Average Both the Q-400 and Q-500 use the following formulas to calculate the accumulated data:
It is used to determine the TWA when the operator wishes to use a measurement time that is different from the
worker's exposure time.
Note that a short term sample can only be used if the average noise in the work area is relatively constant.

For example, a worker is only working a 4 hour day and you wish to determine the worker's TWA by making a 5
minute measurement, do as follows:

1.) Program the Projection Time (Prt) to 4 hours. Note that the preset time period can be set from 1 to 16
Hours in 1/4 Hour steps.

2.) Take a 5 minute sample. This average level is then assumed to be constant over the Projection Time (Prt).
3.) Read out the Projected Time Weighted Average [TWA (Prt)].

TWA: Units: decibels (dB)
Time Weighted Average
It is the sound level that is accumulated for any time period but with its average level computed over an 8 hour time
period.
# If the time period is less than 8 hours, the Time Weighted Average will always be less than the Average
Sound Level (LAVG).
# If the time period is more than 8 hours, the Time Weighted Average will always be more than the Average
Sound Level (LAVG).
It is usually measured with A Weighting, Slow Response, and a 5 dB Exchange Rate. However, the dosimeter will
allow either A or C-Weighting, either Slow or Fast Response, and either a 3, 4, 5, or 6 dB Exchange Rate.
