Description: The Metravi CET series Clamp-on Ground Resistance Testers feature:
Self-test facility. No need to wait a long time to boot. Ready to use immediately after being switched on. Breakthrough relay self-test mode, using the most advanced processing algorithms and digital integration technology, fully intelligent. Handheld device, easy to carry. New design, panel operation with 6 buttons, better performance. Loud sound and light alarms; “beep—beep–beep –” alarm sound. Improved interference signal recognition indicator. Improved anti-jamming capability and test stability. Data storage: 99 Units. Wider range: 0.01Ω-1500Ω. Lower power consumption: Maximum operating current is from 0.0mA to 20A. Are widely used for grounding resistance measurement in power, telecommunications, meteorology, oil fields, construction industries and electrical equipments. In the measurement of a grounding system with loop current, it does not require breaking down the grounding wire and needs no auxiliary electrode. Safe, fast and simple to use. Can measure ground faults beyond the reach of traditional methods and can be applied in situations not in the range of traditional methods. Can measure integrated value of the grounding body resistance and the grounding lead resistance. Also able to measure leakage current and neutral current in the grounding system. |
