High End Adjustment
6. After you have performed the low end adjustment, insert the probe
head into a measurement hole of the high end reference chamber
(e.g. NaCl: 75 % RH chamber in the humidity calibrator HMK15,
use the adapter fitting (13.5 mm)). Note that the difference between
the two humidity references must be at least 50% RH.
7. Let the probe stabilize at least 30 minutes. You can follow the
stabilization by pressing any key, typing C and pressing ENTER.
8. When stabilized, type the high end reference value after the
question mark and press ENTER.
