Chapter 7 Maintenance
In order to obtain the best measurement results, it is very necessary to maintain the sensor regularly.
Maintenance mainly includes cleaning, inspecting damage of the sensor. You can also view the sensor’s
status during maintenance and inspection.
7.1 Sensor Cleaning
It is recommended that the sensor should be cleaned at regular intervals (usually 3 months,
depending on the site environment) to ensure the accuracy of the measurement.
Use water to clean the outer surface of the sensor. If there is still debris, wipe it with a damp soft
cloth. Do not place the sensor in a direct sunlight or near radiation. In the entire life of the sensor, if the
total sun exposure time reaches to one hour, it will cause the fluorescent cap aging and going wrong, and
consequently leading to the wrong reading.

According to the appearance of sensor to check if there is damage; if any damage is found, please
contact after-sales service maintenance center in time for replacement to prevent malfunction of sensor
caused by water from the damaged cap.
