It can be used in any grounding location, whether it is multi-point grounding or single-point grounding, and can test normally. It also generates high-frequency current by itself, which can filter out 50HZ, 100HZ and other harmonic interference currents in the mains. It can also accurately measure even in complex electromagnetic environments. The diameter of the clamp-on ground resistance tester is up to To 50mm, it meets the situation of using flat iron / steel as grounding lead. Special jaw size can be customized according to customer requirements.
