5 Maintenance

The Hygro-Thermo Transmitter is supplied already adjusted and its characteristics remain stable for
years.
Dust does not damage the humidity sensor but does influence the dynamic behaviour negatively. If
the instrument is very dirty, the sensor element can be cleaned or carefully rinsed in distilled water.
Make sure you do not touch the highly-sensitive sensor element.
Before cleaning the sensor elements please remove the protecting filter; it should be cleaned, as
well or should be replaced.
Attention:
The instrument housing with the electronics included should
be opened only in the factory.
