Description
UT-278A can measure the grounding system quickly and safely without disconnecting the circuit ground wire or requiring auxiliary electrodes. The display resolution can reach 0.001Ω, and the leakage current can be measured up to 30A. The clamp part adopts double insulation design, which can effectively block interference signals in the environment. It is the best tool for measuring ground impedance.
