Description
UT278A+ Clamp Earth Ground Tester can quickly and safely measure the grounding system without disconnecting circuit ground lines or the need for auxiliary electrodes. It can measure resistance from 0.01Ω with a resolution of 0.001Ω. UT275 can also measure leakage current up to 30A. This clamps double insulation design makes them durable tools for outdoor work and effective in blocking interference from the environment.
Features of UT278A+
- Data hold
- Data recall
- LCD backlight
- Resistance limit alarm
- Low battery indication
- Auto calibration
- Auto range
