Test Operation Steps

1. First, check whether the current wire, voltage wire, and ground grid wire used for the test have any open circuit (can be measured with a multimeter), whether the rust on the ground stake is cleaned, and whether the burial depth is appropriate (>0.5 meters). Also check whether the test wire and the ground stake are connected properly. If not, handle it and reconnect.

2. The length ratio of the current test wire to the voltage test wire is 1:0.618, and the length of the current test wire should be 3 to 5 times the diagonal of the ground grid.

3. Connect one end of the current test wire and the voltage test wire to the instrument according to the specified length, and lay them out in parallel. Connect the other ends to the two ground stakes respectively (as shown in Figure 2).

4. Check the laid test wires. Connect one end of the multimeter to the current wire or voltage wire, and the other end to the ground grid wire. If there is no resistance reading, it indicates an open circuit. Confirm it is intact before testing.

5. After confirming the connections are correct, connect the instrument to an AC220V/50HZ power supply and power it on.

6. Press the measurement key to start the measurement.

7. After the instrument indicates the test is complete, record the test data.

8. Turn off the instrument power, remove the connections, and the test process is complete.
