Test method of Earth resistance tester

Preparing for the test
1. Before use, you should read the instruction manual of the product to understand the structure, performance and usage of the instrument;
2. Inventory the spare parts and accessories needed in the test and whether the battery power of the tester is sufficient;
3. Disconnect the connection point between the grounding trunk and the grounding body in advance.

Measurement steps
1. Turn on the power switch of the ground resistance tester, and on the operation panel, put the ground electrode E (C2, P2) under test, the potential probe P1 and the current probe C1 in parallel with each other, and insert the two ground pins with a distance of 20 meters. In the soil, make the potential probe in the middle position of E and C. Note that the probe must be outside the ground grid.
2. Then connect the ground resistance tester terminals E (C2, P2), P1, C1 with the position of the probe correspondingly with the special wire, then turn on the power switch of the ground resistance tester “ON”, select the gear and tap the test, the meter head The value displayed on the LCD is the measured grounding resistance.
The measured ground resistance value should be less than 4 ohms (Ω). Different regions or other requirements should be subject to the site.
