Replace the probe filter if it is contaminated. New filters are available from Vaisala.
|CAUTION Be careful when changing the filter, since it is easy to break the sensor when the filter is removed.|
When replacing the filter, wear clean gloves to avoid depositing dirt or oil on the filter.
Replace the filter as follows:
- Turn the filter counterclockwise until it is loose.
Pull the filter straight out carefully.
CAUTION Do not damage the sensor.
- Take the new filter, and insert it to the filter thread.
- Tighten the new filter firmly by turning it clockwise (recommended force 5 Nm).
