1. When the instrument is used, all the metal probes of the moisture sensor must be inserted into the soil and only a part of the probes should be inserted. The displayed data is inaccurate.
2. When inserting the probe, do not bury the plastic part in the soil so that moisture does not enter the sensor and the internal signal processor is short-circuited.
3, if you want to measure the moisture of deeper soil, please dig the land to the required depth, and then measure.
4. When inserting the probe, the plastic part of the sensor must be gripped, and the force is inserted vertically, and the force is incorrect, which will cause the probe to be bent and damaged.
5. When the sensor is removed after the measurement is completed, the plastic part of the sensor must be grasped by hand and then pulled out. Do not pull out the sensor by pulling the wire of the sensor.
6. After use, the soil stuck on the sensor should be wiped with a soft cloth. Do not put it in the water to clean the bath, otherwise it will cause a short circuit in the internal circuit of the sensor.
