6. Insert the sensor probe into the reference humidity 2 (high
calibration point) and stabilise for at least 20 minutes.
7. BUTTON S2: Pressing the button for 5 seconds starts the
procedure for the calibration mode RH. The calibration mode is
indicated by the lit LED "D2" on the circuit board.
8. BUTTON S1 : Pressing the button for 5 seconds starts the
procedure for the high calibration point. The calibration mode is
indicated by the lit LED "D2" and the symbol "CALIB HIGH" will
appear on the optional LC display.
9. BUTTON S1 (up) and S2 (down) : Pressing one of the two
buttons will adjust the measuring value in steps of 0.1% up or
down to the reference value. The actual measuring value is indi-
cated on the display or can be measured with the analogue out-
put. As soon as the measured value is changed, "D1" flashes
resp. disappears when pressing alternating S1 resp. S2.
10. BUTTON S1 (store) : Pressing the button for 5 seconds
stores the calibration value and the procedure is ended. LED
"D2" flashes to indicate exiting of the calibration mode and the
symbol "CALIB HIGH" will disappear from the optional LC
display.
BUTTON S2 (cancel) : Pressing the button for 5 seconds the
calibration procedure will be ended without storing the calibra-
tion values. LED "D2" flashes to indicate exiting of the calibra-
tion mode and the symbol "CALIB HIGH" will disappear from the
optional LC display.
high calibration point:
“CALIB HIGH”
7.2 2-point temperature calibration
•
Start calibration at the low calibration point!
•
The temperature difference between the two points should be at least 30 degC
(86°F)
!
•
Low temperature point < high temperature point
•
Attention: A 2-point temperature calibration is not supported by the configuration
software and must therefore be done directly on the circuit board!
(see the following procedure)
