MANUAL HUMIDITY CALIBRATION
The EE21 transmitter series can be calibrated in two ways.
-
1 point humidity calibration: quick and simple calibration on a defined humidity point
(working point).
-
2 point humidity calibration: simple calibration for accurate measuring results over the
whole humidity working range.
•
To reach a temperature balance it is recommended to keep the transmitter and the
reference chamber (e.g. HUMOR 20,...) for minimum 4 hours in the same room.
•
During calibration procedure it is important to keep the temperature constant.
i
•
For calibration the humidity sensor probe must be stabilised at least 30 minutes into the
reference chamber.
•
Replace a used dirty filter cap before calibration!
2 point humidity calibration
For accurate adjustment over the whole working range or in case of sensor exchanges a
2 point calibration is recommended.
i
•
Start calibration at the low humidity calibration point!
•
The humidity difference between the two points should be > 30%RH
Procedure for 2 point humidity calibration (start at low calibration point):
1. Insert the sensor probe into the reference chamber 1 (low humidity calibration point)
and stabilise for minimum 30 min.
2. PUSHBUTTON Down: Pressing the button for 3 seconds starts the procedure for the
low calibration point. The calibration mode is indicated by the lit LED "Calib".
3. PUSHBUTTON Up and 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 can be measured with the analogue output.
4. PUSHBUTTON Up: Pressing the button for 3 seconds the calibration value is stored
and the procedure is ended. Exiting the calibration mode is indicated by deactivation of
the LED "Calib".
or PUSHBUTTON Down: 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".
5. Insert the sensor probe into the reference chamber 2 (high humidity calibration point)
and stabilise for minimum 30 min.
6. PUSHBUTTON Up: Pressing the button for 3 seconds starts the procedure for the
high calibration point. The calibration mode is indicated by the lit LED "Calib".
7. PUSHBUTTON Up and 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 can be measured with the analogue output.
8. PUSHBUTTON Up: Pressing the button for 3 seconds stores the calibration value and
the procedure is ended. Exiting the calibration mode is indicated by deactivation of the
LED "Calib".
PUSHBUTTON Down: 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".
