Shenzhen cable fault tester manufacturer: introduction of grounding resistance tester Cable fault tester manufacturer Shenzhen cable fault tester manufacturer Shenzhen Noyafa today introduces the grounding resistance tester! Grounding resistance tester abandons the traditional manual Shenzhen cable fault tester Manufacturer: Introduction of Grounding Resistance Tester Cable fault tester manufacturer Today Shenzhen Noyafa, a cable fault tester manufacturer, Shenzhen, will introduce the grounding resistance tester to you! The grounding resistance tester abandons the traditional manual power generation work method and adopts advanced Zhongda A large-scale integrated circuit, a new type of grounding resistance measuring instrument that uses DC/AC conversion technology to combine the three-terminal button and four-terminal button measurement methods into one model. The working principle of the grounding resistance tester is that the DC/AC converter in the machine converts DC into a low-frequency constant current of AC. After the auxiliary grounding electrode C and the measured object E form a loop, an AC voltage drop is generated on the measured object, and the auxiliary grounding The pole P is sent to the AC amplifier for amplification, and then sent to the meter for display after detection. With the override switch, three different limits can be obtained: 0~2Ω, 0~20Ω, 0~200Ω.
