With a calibrated reference instrument, an actual humidity of 78 % rh is measured at
normal operation, with a defined setpoint humidity of
80 %

After the calibration procedure, the reference instrument should display 80.0 %.
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.
