The provided digital earth resistance tester features a 0.010Ω~1500Ω measurement range, 0.00mA~40.0A current range, sound and light alarm function, data storage function and data retention function. Clamp-on ground resistance tester is suitable for measuring the grounding resistance of various equipment. It can also be used for loop resistance measurement, grounding down leads leakage current measurement and judging ground fault.
ATO provides earth resistance testers with a measurement range of 0.00Ω-300kΩ, which are widely used in ground resistance measurement and loop resistance measurement in fields such as electric power, telecommunications, meteorology, oil fields, construction, and industrial electrical equipment. When measuring the grounding system with a loop, the ground resistance tester does not need auxiliary electrodes and does not need to disconnect the grounding wire, which is safer and faster.
