13 Calibration
To perform a calibration, connect the meter to a class 2 or better sound calibrator. Set the meter
as follows:
-
Frequency rating: A

Level range: 50 ... 100 dB
Now switch on both devices and check the displayed measured value. If it is outside the
specifications, it can be adjusted using the adjustment screw.
