How to Use:
1. Hit the P and the grounding nails into the depths of the ground. They are arranged in a row with the equipment to be tested, and they are separated from each other by 5 to 10 meters.
2. This method is to use an exposed low ground resistance object as an electrode when the auxiliary grounding nail is inconvenient to use, such as metal sinks, water pipes, power supply lines, , and building grounding terminals, all of which can be 2‑wire Method (E and P&C end).

Notice:
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.
