The main features of KF-6502 earth network grounding resistance tester are:

The KF-6502 grounding resistance tester is suitable for testing the power frequency grounding impedance and other power frequency characteristic parameters of various grounding devices, as well as soil resistivity. The instrument adopts cross frequency anti-interference technology, which can accurately measure data at the power frequency of 50Hz in strong interference environments. The maximum test current is 5A, which will not cause the potential of the grounding device to be too high during testing. At the same time, it also has strong anti-interference ability, so it can be measured without power outage.
