    UT270 series can measure the grounding system of a circuit without disconnecting the ground wires and auxiliary electrode. It clamps the grounding circuit and measures the grounding resistance fast and safely. It can measure resistance as low as 0.01Ω and has a high resolution of 0.001Ω. It has overload alarm function, which can help to setup the alarm value within the ranges. The clamp has double insulation, which strengthens the anti-interference.
