6. HUMIDITY-/ TEMPERATURE CALIBRATION
The EE07 probe 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.
•
D uring 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!
•
The calibration values are only stored in the probe.

2-point humidity calibration / 2-point temperature calibration

For accurate adjustment over the whole working range a two point calibration is
recommended.
•
S tart calibration at the low calibration point!
•
T he difference between the two calibration points should be > 30%RH / > 30 degC
2-point humidity calibration / temperature calibration procedure
calibration point):
T
1. At the beginning of a humidity calibration set the jumper to RH Calib / for a
RH
temperature calibration set the jumper to T Calib.
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 "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. 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 "Calib" 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 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.
