»ANWENDERHINWEISE FÜR FEUCHTEFÜHLER
At regular environmental condition, it is recommended to calibrate the sensor annually to check the compliance with the accuracy
required in the application.
The following conditions can damage the sensor element or lead in long therm
to loss of the specified
accuracy:
•Contamination (e.g. dust / fingerprints)
•Aggressive chemicals
•Ambient conditions (e.g. condensation on measuring element)
Do not touch the sensor
elements!
Re-calibration or exchange of the sensor element are not subject of the general warranty.
