Clamp ground resistance and leakage current meter Unit UT-275 — 2000 Ω range, 10 A clamp

The Unit UT-275 clamp ground resistance and leakage current meter is designed for contactless measurement of grounding systems and leakage current without disconnecting conductors. It provides ground resistance readings up to 2000 Ω and measures leakage currents using a 10 A clamp, enabling quick verification of earthing integrity and detection of unwanted currents in installations. The compact clamp design and clear display make the instrument convenient for field use by electricians and maintenance personnel.

Advantages

The clamp meter allows non-invasive measurements of ground resistance and leakage current, reducing the need to interrupt circuits or disconnect earth conductors. It supports a wide resistance range up to 2000 Ω for diagnosing a variety of grounding conditions. The 10 A clamp option provides direct measurement of leakage currents on single conductors, improving troubleshooting speed. Built for portability and on-site use, the device combines practical measurement range with straightforward operation and fast results.

Suitable for

• Quick checks of grounding systems in industrial and commercial facilities
• Detection of leakage currents on single conductors without shutdown
• Routine electrical safety inspections and preventive maintenance
• Troubleshooting earthing faults and verifying repair effectiveness

Key specifications

• Ground resistance measurement range: up to 2000 Ω
• Leakage current measurement using clamp: up to 10 A
• Clamp-type, contactless measurement method for conductors and grounding points
• Portable handheld design suitable for field inspections
• Clear visual display for direct reading of values

How to use

Position the clamp around the conductor or grounding conductor to be measured and ensure the clamp is fully closed. For ground resistance checks, follow the manufacturer's instructions for measurement procedure, taking readings at the intended test point and avoiding nearby conductors that could influence results. For leakage current measurement, place the clamp around the single conductor carrying the current; read the leakage value directly from the display. Observe basic electrical safety: wear appropriate protection, ensure the environment is safe, and avoid contact with live terminals beyond what is required for clamp placement.

Usage recommendations

Use the meter for periodic inspections and troubleshooting where contactless measurement increases safety and efficiency. For the most reliable results, take multiple measurements at different points and under normal operating conditions. Keep the clamp clean and store the instrument in a dry, vibration-free environment when not in use.
