Soil Resistivity Tester Troubleshooting Guide

1 Host Cannot Start

Check if the power supply of the grounding resistance soil resistivity tester is normal. Use a multimeter to measure directly on the power input terminal of the host.

2 Test Current Not Available

Check if the connecting wires between the host and the transformer are reliably connected. Both the variable frequency output and measurement feedback wires must be securely connected.

Conduct a simulation experiment using the two resistors inside the accessory box to verify if the instrument can measure accurately and normally.

If it is confirmed that the tester is normal but there is still no current in the test circuit, it indicates that the measurement circuit is open. At this point, check the following:

Whether the instrument wiring is correct

Whether the clamp on the grounding lead is well connected to the grounding lead

Whether the connection between the test line and the grounding pile is good

Whether the joint between the two test lines is well connected

Whether the test line has been broken by passing vehicles

Whether the test line itself is in good condition

If the test current is present but the test voltage is not, it indicates that the current circuit is normal and the voltage circuit is open. Similarly, check the voltage circuit using the same method described above.

3 Test Current Is Very Small

Check if the current pole selection position is reasonable. Try to drive as many grounding piles as possible and drive them deeper.

Splash more water on the current electrode (salt water is more effective).

Check if the clamp on the grounding down wire is well connected to the down wire.

4 Step Voltage / Contact Voltage Cannot Be Measured

Try to increase the test current as much as possible.

There may be an equipotential between the two measurement points. Adjust the position of the two copper disks and re-measure.

Do not measure indoors - data cannot be measured in indoor environments.
