·Major breakthrough in traditional grounding resistance measurement technology, widely used in electric power, telecommunications, meteorology, oil fields, construction and industrial electrical equipment grounding resistance measurement. ·When measuring the grounding system with loop, no need to disconnect the grounding lead, no auxiliary grounding pole, safe, fast, easy to use. ·Can measure ground faults that cannot be measured by traditional methods, and can be applied to occasions that cannot be measured by traditional methods, because the ETCR series of clamp-on grounding resistance meters measure the combined value of grounding body resistance and grounding lead resistance. |
