EE33 Humidity / Temperature Sensor for High Humidity and Chemical Applications
1.
Insert the sensor probe into the reference humidity 1 (low
calibration point) and stabilise for at least 20 minutes.
2. 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.
3.
BUTTON S2:
Pressing the button for 5 seconds starts the
procedure for the low calibration point. The calibration mode is
indicated by the lit LED "D2" and the symbol "CALIB LOW" will
appear on the optional LC display.
4.
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
indicated on the display or can be measured with the analogue
output. As soon as the measured value is changed, "D1"
flashes when pressing S1 or S2.
low calibration point:
2-point humidity calibration procedure on the circuit board:
“CALIB LOW”
5.
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 LOW" 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
calibration values. LED "D2" flashes to indicate exiting of the
calibration mode and the symbol "CALIB LOW" will
disappear from the optional LC display.
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.
high calibration point:
“CALIB HIGH”
