Preparation for calibration

First select the right aperture size for your sound level meter. As standard, 1/1 inch microphones
can be inserted into the aperture. Use the included adaptor for 1/2 inch microphones. The adaptor
can easily be inserted into the standard aperture. For a 1/4 inch microphone, use the optional
adaptor.

Calibration

The calibration procedure for sound level meters within the measurement range of both calibration
points is described below. For sound level meters within the measurement range of only one
calibration point, you can perform only the steps 1-3 with the respective sound level.
1. After turning on the calibrator, use the "94 dB"
2. Carefully insert the microphone into the aperture of the calibrator as far as it will go. The
sound level meter should be placed in the aperture horizontally so that the inner seal is
as high as possible.
3. 3. Wait a short moment for the sound level displayed on the meter to stabilise. Now you
adjust the meter to the 94 dB sound level.
4. If the sound level meter has a measurement range of 114 dB, use the "114 dB"
select the sound level of 114 dB.
5. Compare the sound level displayed on the meter with the calibrator setting of 114 dB. If
the reading is within tolerance, you can finish the calibration and carefully remove the
meter from the calibrator. If the deviation is not acceptable, you must start again with step
