Operating Instructions
Power On/Off
Turn the meter on by pressing the POWER button. To turn the meter off,
press and hold the POWER button for 2 seconds.
Sound Pressure Level (dBA/dBC Mode)
1. At start up, the meter's default settings are "Auto Range",
"A Frequency Weighting" and "Fast Time Weighting".
2. Press and hold the button to select the desired Response Time. If
the sound source consists of short bursts, set the response to FAST
(125ms). To measure average sound level, select SLOW (1 second).
3. Press and hold the button to select the Frequency weighting.
Select "A" Weighting for a general noise sound level, or "C"
Weighting for measuring high level noise. "C" Weighting is a
standard weighting of the audible frequencies commonly used for
the measurement of Peak Sound Pressure Level. If the "C" Weighted
level is much higher than the "A" Weighted level, then there will be a
large amount of low-frequency noise.
4. Press the button to scroll through the three dB range types. There
are two manual dB ranges to select from and an auto range. The
manual ranges are described as follows:
Low (as indicated by "L"): 30 to 80dB range
High (as indicated by "H"): 80 to 130dB range
5. The meter can be held comfortably in one hand, placed in a pocket
or positioned on a tripod for long-term monitoring.
6. Attach the microphone with the provided clip to an area where it will
be exposed to sound levels (i.e. shirt collar).
Note: Set the cable in a way that does not hinder the working movements
of the user. Direct contact with strong winds or blowing air on the
microphone may cause measurement errors.

Data Hold
1. While taking a measurement, press the HOLD button to freeze the
current readings on the display.
2. While in this mode a "HOLD" symbol will appear.
3. Press the HOLD button again to resume normal operation.
Note: When the Data Hold feature is active all buttons except the POWER
button are disabled.
Recording Maximum and Minimum Readings
1. Press the RUN/PAUSE button to enter recording mode as indicated
by "REC" on the LCD. The meter will now begin recording maximum
and minimum readings.
2. While in recording mode:
A) Press the RUN/PAUSE button once and the maximum value
will appear on the display as indicated by "REC MAX".
B) Press the RUN/PAUSE button again and the minimum value
will appear on the display as indicated by "REC MIN".
C) To exit recording mode and resume normal operation, press
and hold the RUN/PAUSE button for approx. two seconds.
Note: When in recording mode the POWER button is disabled and the
meter cannot be turned off.
Backlighting
Press the BACKLIGHT button to turn the LCD Backlight on. It will
automatically turn off after approx. 5 seconds.
The R8085 is designed to calculate and display an individual's noise exposure in
%DOSE on the LCD display. All stored readings that are captured during the modes
described in this manual can be accessed, and exported to Excel for further analysis by
using the optional PC software (R8085-PC) and USB cable (R8085-USB).
What is Dose Noise Exposure?
The unit of measure, %DOSE, is used to quantify noise exposure that is
measured during an employee's work shift. 100% dose is the maximum
allowable noise exposure in accordance with OSHA, CCOHS, MSHA,
DOD, ACGIH, and ISO standards. Most standards specify what specic
Criterion Level, Exchange Rate, Response Time, and Frequency weighting
the dosimeter should be set up with in order to meet these
specic standards.

12
According to OSHA's noise standard, specically, 29 CFR 1910.95, the
dosimeter must be set up to record noise exposure using the
following criteria:
• Exchange rate: 5dB
• Frequency weighting: A
• Response: Slow
• Criterion level: 90dBA (Hearing Conservation) or 90dBA (Administrative
and Engineering Controls).
• Threshold: 80dBA (Hearing Conservation) or 90dBA (Administrative and
Engineering Controls).
The Dosimeter allows for testing to begin immediately which is referred to
as a Test Duration (DUR) or with programmable beginning and end times
(BEG & END). Both modes are described in the following 2 sections.
Noise Exposure (%DOSE) - Test Duration Mode
1. Press the FUNC. button until you see SPL on the LCD.
2. Press and hold the button to select the desired Response Time.
3. Set the Criterion Level (Lc), Exchange Rate (ER), and Threshold Level
(Lt) (see Setup Mode section for details).
Note: At start up, the meter's default settings are Lc 90, Lt 70,
ER 3.
4. Press the FUNC. button to enter the %DOSE mode. By default, the
meter will be set to test duration (DUR).
5. Press and hold the button to set the duration time required
for testing.
6. Use the and buttons to select between the following
duration times:
24Hr 12Hr 10 Hr 8 Hr 4 Hr
2Hr 1Hr 30 minutes 15 minutes 10 minutes
5 minutes 1 minute
7. Press the ENTER button to conrm selection and return to the
main screen.
Note: Make sure you have enough memory to complete your noise survey
(see Clear Stored Data in Setup Mode section for details).
8. The meter can be placed in a pant or shirt pocket.

1 Power on the meter.
2 Press the FUNC. button to ensure you are in SPL mode.
3. Select "80 - 100dB" (Hi) range.
4. Select "FAST" time weighting.
5. Select "A" weighting.
6. Insert Microphone into the sound calibrator's microphone adapter.
7. Power on the sound calibrator (R8090).
Note: If the measured value is not within "94 ±0.2" dB, adjust the meter's
calibration by entering calibration mode.
