How to carry out calibration
Please note: the calibration is only possible, if the logger memory is empty.
Start calibration: press "CAL" (key 3) for 2 sec.
(after more than 10 sec. the factory calibration will be set)
The display prompts you to measure the first humidity value. Use "Set"-key (key 4) to stop calibration whenever you
want to. In such a case the last calibration before this one will be used.
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 detec-
tion, 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 yet (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 de-
tected 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.
Except this, same procedure as above. As soon as the display stops blinking and chang-
ing 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 TFS0100 Calibration" in chapter 12.
