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.
Tips: Test methods of ground resistance tester
Common testing methods for ground resistance testers include the two-wire method, three-wire method, four-wire method, single-clamp method and double-clamp method, each of which has its own characteristics. In the actual measurement, the user should try to choose the appropriate test method to make the test result accurate.
