ETCR2000A clamp-type ground resistance meter is also called clamp-type ground resistance meter, ground resistance meter, loop resistance tester, single clamp ground resistance tester, which is used for ground resistance, loop resistance measurement, and ground fault judgment. When measuring a grounding system with a loop, there is no need to disconnect the grounding lead, and no auxiliary grounding electrode is required. It is safe, fast and easy to use. Clamp-type ground resistance meters are widely used in ground resistance measurement and loop resistance measurement in power, telecommunications, meteorology, oil fields, construction and industrial electrical equipment. The long jaws are particularly suitable for places where flat steel is grounded.
ETCR2000A can measure ground faults that cannot be measured by traditional methods, and can be used in places where traditional methods cannot be measured, because the clamp-type ground resistance meter measures the comprehensive value of the ground body resistance and the ground lead resistance.
