RDER2100C+ Multi-Function Clamp Earth Resistance Tester is widely used in the grounding resistance measurement of the power, telecommunications, meteorology, oilfield, construction and the industrial and electrical equipment. In the measurement of a grounding system with loop, does not require breaking down the grounding down lead, and no need the auxiliary electrode. It is safe, fast and simple in use. The tester can measure ground faults which cannot be measured by traditional methods. It can be used in applications where traditional methods cannot be measured, because the RDER series clamp grounding resistance meter measures the combined value of grounding body resistance and grounding lead resistance. The equipment can also measure the leakage current and neutral current of the grounding system.
