Before applying compressed air to an assembly with cleaning facility, make sure the connections
are correctly fitted. Otherwise, the assembly may not be insert into the process.
4.2
Polarization
The sensor was tested in the factory for perfect functionality and is supplied ready for operation.
To prepare for calibration, proceed as follows:
1.
Remove the sensor protective cap.
2.
Place the externally dry sensor in atmospheric air. The air should be saturated with water
vapour. Therefore, install the sensor as close to the water surface as possible. When
calibrating the sensor membrane, make sure the membrane remains dry. Therefore, avoid
any direct contact with the water surface.
3.
Connect the sensor to the transmitter and switch on the transmitter.
