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:

  1. Turn the filter counterclockwise until it is loose.
  2. Pull the filter straight out carefully.
    CAUTION Do not damage the sensor.
  3. Take the new filter, and insert it to the filter thread.
  4. Tighten the new filter firmly by turning it clockwise (recommended force 5 Nm).
