The grounding resistance meter is used to test the grounding resistance of various devices in departments such as power, postal and telecommunications, railways, communication, mining, etc., as well as to measure low resistance conductor resistance values, soil resistivity, and ground voltage. Grounding resistance tester is an instrument used to measure the grounding resistance value and soil resistivity of electrical equipment grounding devices. The ground resistance of the grounding electrode is the soil resistance from the grounding electrode to zero potential, and is generally measured using the compensation method. A grounding resistance tester based on compensation principle is called a "potentiometer type grounding resistance tester", with an error range of generally ± 5%. In addition, there are also current ratio meter type grounding resistance testers, with an error range of generally ± 10%
