Over time, the probe filter becomes
contaminated with matter that you cannot remove by cleaning. When this happens, the response
time becomes longer and measurement accuracy decreases.
CAUTION The Pt100 temperature
sensor is soldered to the probe. Do not try to remove it. Due to the operating principles of
the sensor, no maintenance is required.
Remove the probe from inside the radiation shield.
Carefully remove the filter from the probe. Holding the filter by the plastic part,
rotate the filter counterclockwise and pull it out.
CAUTION Do not touch the
sensor heads.
