Calibrating
Quest Technologies recommends 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 calibration.

Calibrating the dosimeter
1. Remove the windscreen from the dosimeter by unscrewing it. (See
Figure 6-1 for an illustration, page 51.)
2. Ensure the Edge is turned on and in the stop mode. (See “Turning on”
page 8, and “Turning Off” page 9).
3. Slide the Edge into the mouth of the calibrator.
✍
NOTE: ensure the adapter ring is inserted into the mouth of the calibrator before you
slide the Edge 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 flash on the display when detected.
6. Press the on/off 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 on/off
enter button.

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.
9. To return to the measurement view screen, press the on/off enter
button.
10. To end the calibration steps, turn off the calibrator. Detach the
dosimeter from the calibrator.
