1-point humidity calibration / 1-point temperature calibration

When the working range is limited to a certain more narrow range, a calibration at one
humidity point / temperature point is sufficient.
•
In accordance with the working range, either the high or low calibration point should
be selected. (CP > or < 50% RH / CP > or < 50% of measurement value)
•
This calibration causes an extra inaccuracy for the rest of the working range.
1-point humidity calibration / temperature calibration procedure
1. At the beginning of a humidity calibration set the jumper to RH Calib / for a
temperature calibration set the jumper to T Calib.
2. Insert the sensor probe into the reference humidity / reference temperature
(calibration point) and stabilise for at least 30 minutes.
3. BUTTON S1 (Calibration point > 50% RH / > 50% of measurement value): Pressing
the button for 3 seconds starts the procedure. The calibration mode is indicated by the
lit LED "Calib" and by the symbol "CAL>" on the LC display.
or
BUTTON S2 (Calibration point < 50% RH / < 50% of measurement value): Pressing
the button for 3 seconds starts the procedure. The calibration mode is indicated by the
lit LED "Calib" and by the symbol "CAL<" on the LC display.
4. BUTTON S1 (up) and S2 (down): Pressing the two buttons will adjust the measu-
ring value in steps of 0.1% / 0.1 degC up or down to the reference value. The actual
measuring value is indicated on the display or can be measured with the analogue output.
5. BUTTON S1: Pressing the button for 3 seconds the calibration value is stored in the
probe and the procedure is ended. Exiting the calibration mode is indicated by
deactivation of the LED "Calib" and the symbol "CAL" on the LC display.
BUTTON S2: Pressing the button for 3 seconds the calibration procedure will be
ended without storing the calibration values. Exiting the calibration mode is indicated
by deactivation of the LED "Calib" and the symbol "CAL" on the LC display.
6.3 Resetting the customer calibration to the factory calibration:
BUTTON S1 and S2: To reset the RH or T values, the jumper has to be set on the
respective location before starting the factory calibration.
In neutral mode pressing both buttons simultaneously for 5 seconds customer calibra-
tion settings are reset to factory calibration.
A short flash of the LED "Calib" indicates the reset.
