UT276A+ can quickly and safely measure the grounding system without disconnecting circuit ground lines or the need of auxiliary electrodes. It can measure resistance from 0.01Ω with a resolution of 0.001Ω. This clamp’s double insulation design makes it a durable tool for outdoor work and effective in blocking interference signals from the environment.
