This device applies to test frequency ground resistance, contact voltage, pace voltage and earth electric resistivity.
Features
1. Good frequency equivalence. sine wave(measured current wave), two frequencies for testing.
2. Strong anti-jamming ability, test results stable, reliable. Error caused from 15V/50Hz disturbance: 0.001Ω
3. High precision, can test the ground network of small impedance.
4. Powerful: test all characteristic parameters like ground impedance, resistive and reactance component
5. disconnection alarm function
6. Easy to operate, menu operated, directly display the test results.
7. Do not need high current wire.
8. small volume, little weight, convenient to carry
