The grounding resistance tester is a new type of digital resistance tester. It abandons the traditional manual power generation method,Earth Resistance Tester adopts advanced large-scale integrated circuits,Earth Resistance Tester adopts DC/AC conversion technology,Earth Resistance Tester and measures the three-terminal button and the four-terminal button. Combined with a new digital tester. It is suitable for the measurement of grounding resistance and low resistance conductor resistance of various equipment in power,Earth Resistance Tester post and telecommunications, railways, communications,Earth Resistance Tester mining and other departments. It can also measure soil resistivity and ground voltage.

The resistance tester should be placed indoors with an ambient temperature of 0°C to 40°C and a relative humidity of not more than 80%. In addition,Earth Resistance Tester the air must not contain harmful substances that may cause corrosion. It is a commonly used instrument for detecting and measuring grounding resistance,Earth Resistance Tester and an indispensable tool for electrical safety inspection and completion acceptance of grounding projects. The functions of the ground resistance tester are as follows. Accurately measure the grounding resistance,Earth Resistance Tester grounding resistance and grounding reactance of large grounding grids.

Accurately measure the surface potential gradient of large grounding grids. Accurately measure the contact potential difference,Earth Resistance Tester contact voltage, step potential difference and step voltage of a large grounding grid. Accurately measure the transmission potential of a large grounding grid. The grounding resistance tester is composed of a hand-held generator, a current transformer,Earth Resistance Tester a sliding wire resistance, a reactor,Earth Resistance Tester etc. All mechanisms are installed in a plastic casing, which is easy to carry. The accessories include auxiliary probe wires,Earth Resistance Tester etc. The auxiliary probe wires are installed in the accessory bag. Its working principle is reference voltage comparison. The DC/AC converter in the device converts DC to AC low-frequency constant current. This circuit is composed of an auxiliary ground electrode C and the measured object E,Earth Resistance Tester and generates an AC voltage drop on the measured object. The auxiliary ground electrode P is sent to the AC amplifier for amplification,Earth Resistance Tester and then the measured object is sent to the meter display.
