Note
Up to this point, you can break off the calibration procedure at any time
with the
e
key. The system continues to work with the old calibration
data. However, you have to switch off the maintenance condition in any
case.
After starting the calibration with the
g
key (step 4), you cannot break
off the calibration any more.
Note
In the case of air temperatures under 5 °C do not calibrate the sensor
in air but in air-saturated water that has a higher temperature. You
obtain air-saturated water by pouring water several times in and out of
two vessels so that it sparkles. Then immerse the sensor in a vessel
with air-saturated water and calibrate as described above.
Possible results of the
calibration
The calibration data are evaluated by the system. A calibration can
have the following results:
3 Bring the sensor into the calibrating position.
To do so, position the sensor approx. 2 cm above a water
surface, best in a narrow bucket or similar container with water.
When doing so, no liquid should be brought on the membrane.
4 Continue with
g
.
The calibration data is automatically determined and
documented in the calibration record.
5 Complete the calibration procedure according to the
instructions on the display.
