The procedure of dew point and frost point calibrations are equal with
the procedure of humidity calibrations!
The EE23 transmitter series can be calibrated in two ways:
-
1-point humidity / temperature calibration: quick and simple calibration on a defined
humidity / temperature point (working point).
-
2-point humidity / temperature calibration: simple calibration for accurate measuring results
over the whole humidity / temperature 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!
•
For calibration the humidity sensor probe must be stabilised at least 30 minutes in
the reference chamber.
•
Replace a used dirty filter cap before calibration!
2-point humidity calibration / 2-point temperature calibration
For accurate adjustment over the whole working range a two point calibration is recommended.
•
Start calibration at the low calibration point!
•
The difference between the two calibration points should be > 30%RH / > 30 degC
2-point humidity calibration procedure / temperature calibration procedure (Start at
low calibration point):
1. At the beginning of a humidity calibration set the jumper to CAL RH
temperature calibration set the jumper to CAL T.
2. Insert the sensor probe into the reference humidity / reference temperature 1
(low calibration point) and stabilise for at least 30 minutes.
3. BUTTON S2: Pressing the button for 3 seconds starts the procedure for the low
calibration point. The calibration mode is indicated by the lit LED "D1" 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 and
the procedure is ended. Exiting the calibration mode is indicated by
deactivation of the LED "D1" 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 "D1" and the symbol "CAL<" on the LC display.
6. Insert the sensor probe into reference humidity / reference temperature 2 (high
calibration point) and stabilise for minimum 30 min.
7. BUTTON S1: Pressing the button for 3 seconds starts the procedure for the high
calibration point. The calibration mode is indicated by the lit LED "D1" and by the
symbol "CAL>" on the LC display.
8. 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.
9. BUTTON S1: 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 "D1" 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 "D1" and the symbol "CAL>" on the LC display.
