Feature:
1. It can be used to measure the ground resistance value of various power facility wiring, electrical equipment, anti thunder equipment and other grounding devices, and it can also measure ground voltage.
2. This professional digital insulation earth resistance tester has stable performance and reliable result. A variety of gears are suitable for more environments, and the voltage and resistance gears can be switched.
3. Reinforced insulation safety structure and double insulation safety make the measurement safer and more assured. 20 sets of data can be stored.
4. It has more complete functions, higher accuracy. It is equipped with a warning of poor contact of the test line, over range display, and over range display OL.
5. Comes with a portable carrying case, easy to carry, more convenient and reliable for operation and more suitable for outdoor use.

Note:
Make sure that the grounding nail is inserted in the moist soil. If the soil is dry, you must add enough water and the stone or sandy ground must become damp before testing. Use the existing auxiliary grounding nails) to lay flat on the concrete floor, put a wet towel, and pour enough water to replace the measuring electrode. Generally, the measurement can be carried out.It can be used to measure the ground resistance value of various power facility wiring, electrical equipment, anti thunder equipment and other grounding devices, and it can also measure ground voltage.
