Maintenance methods
Sensor maintenance
1) Sensor outer surface: Clean the outer surface of the sensor with tap water. If there isstill debris left, wipe it with a soft, damp cloth.

For some stubborn dirt, some household washing liquid can be added to the tap waterfor cleaning.

2) Check the cable of the sensor: The cable should not be tightened during normaloperation, otherwise the internal wires of the cable may be broken and the sensor may not work properly.

3) Check if the sensor's measurement window is dirty .

4) Check the sensor housing for damage.


Notice: The probe contains sensitive optical and electronic components. Make sure the probe is not subject to severe mechanical shock. No need inside the probe
