Question:

The earth resistance tester is an instrument for measuring the insulation resistance of a line, isn't it?

The earth resistance tester is an instrument for measuring the insulation resistance of a line, isn't it?

Answer:

No, the grounding resistance tester is applicable to electric power, telecommunications, railways, communications, mining and other departments to measure the grounding resistance of various devices and measuring low resistance conductor resistance, but also the soil resistivity measurement instrument and voltage.
Because of the grounding resistance are relatively small (less than 0.1), and the insulation resistance are relatively large (minimum in 1M, can reach the maximum of 500M or even infinite), because the ground resistance tester can test the insulation resistance, insulation resistance measurement using insulation resistance meter (megameter) to measure.
