UT278A+ series 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. These clamps’ double insulation design makes them durable tools for outdoor work and effective in blocking interference from the environment.

• Auto range
• Data hold
• Data recall
• LCD backlight
• Resistance limit alarm
• Low battery indication
• Auto calibration
• Visual & audible alarm
• Auto power off
• Jamming signal recognition
• Over-range display
