    Features

    1The grounding resistance measuring instrument is constructed with high-strength aluminum alloy as the casing. In order to prevent industrial frequency and rf interference, the phase-locked loop synchronous tracking and detection mode is adopted on the circuit, and the switch capacitor filter is equipped to make the instrument have better anti-interference ability.

    2DC/AC conversion technology is adopted to convert DC into AC low-frequency constant current for easy measurement.

    3Allow auxiliary grounding resistance of 0 ~ 1.8kω (RC), 0 ~ 40KΩ (RP) shall not affect the result of measurement.

    4the grounding resistance measuring instrument does not need manual adjustment and balance, 3(1/2) position LCD display, in addition to measuring the earth resistance, but also can measure low resistance conductor resistance, soil resistivity and ac voltage. If the test circuit does not display &ldquo on the header; 1 & throughout; Stands for overflow, in line with conventional measurement habits.
