Sensor maintenance
Fluor cap inner surface:
If water vapor or dust intrudes into the inside of the fluorescent
cap, the cleaning steps are as follows:
- Remove the fluorescent cap
- Flush the inner surface of the fluorescent cap with tap water
- For fats containing fat and oil, wash with warm water with
household washing solution
- Flush the inner surface of the fluorescent cap with deionized water
- Gently dry all surfaces with a clean lint-free cloth and place in a
dry place to allow the water to completely evaporate.
Check the cable of the sensor:
- The cable should not be tightened during normal operation,
otherwise the internal wire of the cable may be broken, causing the
sensor to not work properly;
- Check the sensor's outer casing for damage due to corrosion or
other causes.
