Example: Humidity deviation at 90 % should be corrected.
1. Set humidity balance point in the SETUP to RH 90 and set the accompanying compensation
correction value to 0.0 %rh:

2. With a calibrated reference instrument, an actual humidity of 88% rh is measured at nor-
mal operation, with a set setpoint humidity of 90 %rh.
3. Set the compensation correction value in the SETUP for RH 90 to –2.0 %rh:

4. The reference instrument should display 90.0% rh after the calibration procedure.
With RH 20 a further comparison can be programmed at 20 % relative humidity.
If all compensation correction values are set to 0.0 % rh, the factory calibration settings
are restored.
