1)
Selection automatic detection / manual input
Press "CAL"-key (key 3) for a short time to switch over between the various
possibilities existing:
automatic detection
(acceptable humidity variables see above)
Display will switch over between the acceptable variables.
manual input
If you want to use other humidity values than those provided
in the automatic detection, please enter them here.
0 ... 100.0 %: input range for rel. atmospheric humidity.
(please note Watch out for 'Automatic temperature
compensation during calibration')
2)
Calibration point 1
Put sensor in suitable calibration equipment.
- As long as the individual values in the display for the
automatic detection keep changing, a valid value could not be
detected (humidity value measured may deviate from value set
by manufacturer by approx. 10 %).
- In case of manual input, enter value here.
As soon as the display stops blinking and changing between
values, a stable value has been detected and can be taken
over by means of the "Store"-key (key 6). Then the next
calibration step will be displayed.
3)
Calibration point 2
Put sensor into suitable calibration equipment prepared for the
second humidity value.
Precondition: If the first value was below 50 %, this value has
to be over 50% or vice versa. Otherwise proceed as above. As
soon as the display stops blinking and changing between
values, the measuring value can be taken over by means of
the "Store"-key (key 6) and the calibration has been completed.
If error messages are displayed when calibrating the instrument, the old
calibration keeps valid, the new calibration data are lost. Please refer to "Error
and System Messages during HND-FF31 Calibration"
