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. |
-
Carefully remove the filter from the probe. Holding the filter by the plastic part,
rotate the filter counter-clockwise and pull it out.
CAUTION Do not touch the sensor heads.
