13 Maintenance

Cleaning of the sensor
The sensor can be cleaned by carefully moving it to and fro in destilled water or isopropanol.
Attention:
Do not touch the surface of the sensor plate.
Avoid mechanical impact on the sensor (e. g. by means of a sponge or a brush).
If the soiling cannot be removed the sensor has to be inspected and maintained by the manufacturer.

14 Calibration/ Adjustment

We recommend an annual calibration resp. adjustment at the manufacturer.
Please observe the attached inspection certificate.
