Turning On / Turning O
1) To turn on the dosimeter, press the On/O button. The splash screen will appear indicating the rmware
version. After the splash screen disappears, the screen will be in the measurement view.
2) To turn o the dosimeter, press and hold the On/O button. A “3, 2, and 1” countdown will appear as the
dosimeter is powered o.

Calibrating
It is recommended to calibrate your dosimeter before you run your study(ies) and
after your study(ies) to ensure highly accurate measurement results. The steps
below address how to calibrate for either a pre or post study.
Calibrating the dosimeter
1) Remove the windscreen from the dosimeter by twisting and pulling the
black ring (do not pull on the foam).
2) Ensure the dosimeter is turned on and in the stop mode. (See “Turning on”
and “Turning O”.)
3) Slide the dosimeter into the mouth of the calibrator.
NOTE: Ensure the adapter ring is inserted into the mouth of the calibrator
before you slide the dosimeter into the cavity.
4) Turn on the calibrator and ensure parameters are set to 114 dB and 1000 Hz.
(See calibration manual for operation details.)
5) CAL” will ash on the display when detected.
6) Press the Enter button to trigger the calibration display.
7) To match the values on the calibration display, press repeatedly the Up or Down
arrow in order to select the exact output on the calibrator (i.e., 114 dB).
8) When you have selected the appropriate dB level, press the Enter button.
9) A shaded bar will appear loading your calibration information. Then a
summary calibration screen will appear indicating the dB level with date
and time displayed.
10) To return to the measurement view screen, press the On/O button.
11) To end the calibration steps, turn o the calibrator. Detach the dosimeter
from the calibrator.
NOTE: A manual calibration can be started by simultaneously pressing the
Up/Down Arrow keys.

Setting up the Quest™ Edge 7 Dosimeter
The EG7 model comes equipped with four customizable user setups. You have the option to customize the
parameters for threshold values, exchange rate values, ltering, an upper limit value, and a criterion level.
The EG7 model also has the 1/1 octave capability that can be enabled via DMS.

Overview of Running a Study
On Quest™ Edge 7 dosimeters, with the introduction of the Pause functionality, the time between Run and
Stop is considered a session. If a user does a Run, Pause, Run, Pause, Stop, the data in DMS will show two
studies within a Session. The downloaded le in DMS will show a ‘+’ symbol on the left. Clicking on it will
dropdown a ‘Study 1’ and ‘Study 2’ options.
Quick Help List: Typical Dosimetry Session
1) Turn the dosimeter on and check your battery power.
2) Set up your study parameters via DMS.
3) Calibrate the dosimeter.
4) Attach the dosimeter for your personal noise study.
5) Press the Run soft key button to start a session.
6) When you are ready to pause your session, press the Pause soft key button.
The previously recorded data is now classied as a study.
7) To stop the session, press the Stop soft key button .
8) Review your results either on the meter, via Quest™ Edge dB APP (on Bluetooth®-enabled devices)
or download to DMS for further analysis (graphs/charts, saving and printing).

Additional Features (See User Manual for Specic Use Instructions)
The Octave Band Graph displays the SPL (Sound Pressure Level) and Lavg or Lmax values/graph for
each frequency band in a given audio spectrum (Note: refer to pages 34-35 in the DMS manual for more
information on this feature).
The Session Review screen allows reviewing of the last 5 sessions stored on the device. It will display
the Start time, Run time, Lavg and Dose for those sessions.
Audio Recording When enabled (checked) in DMS this function will automatically record audio of a noise
event above a congurable dB level.
Voice Notes When enabled (checked) in DMS, the user can, by the press of a button, make verbal notes
about location description or noise events, which will display in the time-stamped data set.
Ceiling Threshold is congurable based on dB level and time period for which ceiling is exceeded.
Ceiling Count is the number of times the sound level measured by meter 1 has exceeded the ceiling
threshold settings.

Charging your Dosimeter
How to Charge
1) Plug in the power adapter to the EdgeConnect charging dock
(see power adaptor below).
▪The EdgeConnect’s lower LED will appear solid when powered on.
2) Slide the dosimeter downward onto the hook of the EdgeConnect
until it clicks. It will be fully seated.
NOTE: The top LED will appear as red ashing and will change to
solid green when fully charged.

Common Noise Dosimeter Terms
Criterion Level (CL) - expressed in decibels (dB), it is the maximum allowable accumulated noise
level that results in 100% dose. Regional noise standards specify criterion level.
Dose - expressed in percent, it is the percent of the maximum exposure that has accumulated
over the run time. 100% is the maximum allowable exposure. 100% dose occurs for an average
sound level equal to the criterion level for an 8 hour period.
Exchange Rate (Doubling Rate) (ER)- the decibel level that would double or halve the sound
exposure. For instance with a 3 dB exchange rate the sound exposure doubles with every
3 dB increase, and the sound exposure is halved every 3 dB decrease. Regional noise standards
specify the exchange rate.
Lavg - stands for “level average” and is the average sound level measured over the run time.
Leq - stands for “level equivalent” and is the average sound level measured over the run time but
is calculated with a 3 dB exchange rate with no threshold.
Max Level - the highest weighted sound level that occurred, also allowing for the response time
that the meter is set to. If the meter is set for A weighting with Slow response then the Max level
is the highest A weighted sound that occurred applying the Slow response time.

11
Peak level - the highest instantaneous sound level that the microphone detects. Unlike the Max
Level, the peak is detected independently of the slow or fast response time the unit is set for.
Response Time (Fast, Slow, Impulse) - how quickly the circuitry responds to changing noise
levels. These are ANSI/IEC dened response times. Most occupational noise standards require
slow response time.
Threshold Level (Cut O) - noise levels below the threshold are integrated as zero decibels.
This will aect Lavg, Leq, TWA, and Dose values. Most regional noise standards specify the
threshold level, if any.
TWA (Time Weighted Average) - takes the noise exposure accumulated in the run time and
applies an eight hour time period. If the meter was in run for 5 minutes, the TWA takes that
5 minutes of noise input and averages it into an 8 hour run time. The TWA in this case would
be much lower than the Lavg.
Weighting (A,C,Z) - frequency lters that cover the frequency range of human hearing.
A weighting greatly attenuates high and low frequency noise to mimic how the human ear
hears noise. C weighting also attenuates high and low frequency noises, but not nearly as
much as A weighing. Z weighting does not apply any attenuation, or weighting, to any frequency.
Most regional noise standards require a weighted measurements.
