Two points calibration for relative humidity
CAL2L, CAL2H: the lower adjustment value can be calibrated in
menu CAL2L whereas the upper adjustment value can be
calibrated in menu CAL2H. The lower value should lay between
10%...40% r. h. (preferably 33%r.h.) and the higher value should
lay between 60...90% r.h. (preferably 76%r.h.).
A two points calibration is only possible within the range !.
+/- 10% rel hum. is the max. offset that can be given per point.
It can be set gradually with 0,1%.
Important: Two points calibrations should rather be carried
out by accredited calibration laboratories !
Factory calibration can be obtained by entering offset 0.0
