Maintenance
3.1. Sensor cleaning
Cleaning the WSPS 05 is necessary from
time to time, especially if the sensor is being
used for different fluids.
As cleaning fluid, clean petroleum benzin
or even clean Isopropanol can be used.
When cleaning the sensor, please remove
the protective cap and proceed with
extreme caution.

Calibration
4.1. Water saturation
Upon delivery of the WSPS 05 is calibrated based on defined salt solutions.
It is recommended to carry out an annual examination of the calibration
by comparison
with a hygrometer in air
. In case of variations > 5%, the sensor is to be sent to the
manufacturer for a new calibration.
4.2. Integrated temperature sensor
Upon delivery of the WSPS 05 the integrated temperature sensor is calibrated.
An annual examination of the calibration at ambient temperature is recommended using a
commercially available thermometer. If a new calibration is necessary (variation of the rated
value> 10%) the sensor must be sent to the manufacturer.
