Humidity calibration
Humidity control can be adjusted according to customer requirements by means of three
freely selectable balance points. For each selected calibration point, a positive or negative
compensation correction value between –10 % and +10 % can be set (Fig. 28).
For humidity adjustment, you will need a calibrated reference measuring device.
