Measuring principle
Electrical Wiring
一.Instructions1.1 Quick test method
Select a suitable measurement location, avoid stones, and ensure that the steel needle does not touch hard objects. Discard the topsoil according to the required measurement depth, and maintain the original tightness of the soil below. Hold the sensor vertically and insert it into the soil. It is not allowed to shake left and right, it is recommended to measure multiple times to find the average value within a small range of one measurement point.
1.2 Buried survey
Vertically dig a pit with a diameter of> 20cm, insert the sensor steel needle horizontally into the pit wall at a predetermined depth, bury the pit tightly, and stabilize it for a period of time, then you can perform continuous measurement for several days, months, or even longer.
1.3 Precautions
1). All steel needles must be inserted into the soil during measurement.
2). Avoid direct sunlight on the sensor, which will cause excessive temperature. Pay attention to lightning protection in the field.
3). Do not bend the steel needle violently, do not pull the sensor lead wire with force, and do not beat or violently hit the sensor.
4). The protection grade of the sensor is IP68, which can soak the sensor in water.
5). Due to the presence of radio frequency electromagnetic radiation in the air, it should not be energized in the air for a long time.
