The digital grounding resistance tester adopts advanced medium and large scale integrated circuits,Earth Resistance Tester and uses DC/AC conversion technology to combine the three-terminal button and four-terminal button measurement methods into a new type of grounding resistance meter. The working principle is that the DC/AC converter in the machine converts DC into AC low-frequency constant current,Earth Resistance Tester and forms a loop through the auxiliary ground electrode C and the test object E. An AC voltage drop occurs on the test object and is fed into the auxiliary ground electrode P The AC amplifier is amplified and then sent to the meter display after detection. With the help of the magnification switch,Earth Resistance Tester three different limits can be obtained: 0～2Ω, 0～20Ω, 0～200Ω.

The digital grounding resistance tester is a major breakthrough in traditional grounding resistance measurement technology, and is widely used in the grounding resistance measurement of electric power,Earth Resistance Tester telecommunications,Earth Resistance Tester meteorology, oil fields, construction and industrial electrical equipment. When measuring the grounding system with a loop,Earth Resistance Tester the clamp-on grounding resistance meter does not need to disconnect the grounding down conductor and no auxiliary electrode,Earth Resistance Tester which is safe, fast and easy to use. The digital ground resistance tester can measure the ground fault that cannot be measured by the traditional method, and can be applied to the occasions that cannot be measured by the traditional method,Earth Resistance Tester because the clamp ground resistance meter measures the combined value of the resistance of the ground body and the resistance of the ground lead.Earth Resistance Tester The clamp-shaped grounding resistance meter has long jaws and round jaws.Earth Resistance Tester Long jaws are particularly suitable for flat steel grounding.
