Digital High-Voltage Ground Resistance Tester

Main Features

· The housing is made of high-strength aluminum alloy. In the circuit, to prevent power frequency and RF interference, phase-locked loop synchronous tracking detection is adopted, combined with a switched capacitor filter, giving the instrument good anti-interference capability.

· DC/AC conversion technology is used to convert DC into a low-frequency constant current for easy measurement.

· The allowable auxiliary ground resistance can vary between 0～2KΩ (RC) and 0～40KΩ (RP) without affecting the measurement results.

· This instrument does not require manual balance adjustment. It has a 3(1/2)-digit LCD display. In addition to measuring ground resistance, it can also measure low-resistance conductor resistance, soil resistivity, and AC ground voltage.

· If the test loop is not connected, the display shows "1" indicating overflow, which conforms to conventional measurement habits.
