6. Note down the real humidity value.
7. Compare the noted displayed measuring value with the real humidity value.
» If the indicated value shows a difference higher than 1.5 % relative humidity, it is
recommended to perform a recalibration. A calibration can be performed by the
company Schaller Messtechnik GmbH.
» It is also possible to run the calibration by yourself using the calibration am-
poules: For instructions on how to perform calibration, please contact Schaller
Messtechnik GmbH or your distributor.
