Calibration in water vapor-saturated air
Calibrating position
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
(calibrating position) and calibrate as described above.
1
If necessary, clean the sensor and membrane and dry the
membrane (see section 5.2 C
).
2
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.
3
Start calibration as described in the operating manual of the
measuring transmitter.
