Major Tech Earth Resistance & Leakage Current Clamp Tester – MT332

Simplify earthing system evaluations and ground resistance measurements with the Major Tech Earth Resistance Clamp Tester (MT332). Engineered for electrical contractors, utility maintenance technicians, and grounding system inspectors, this specialized instrument measures earth ground loop resistance from 0.001Ω to 1200Ω without disconnecting ground rods. Equipped with simultaneous resistance and current display, noise interference filtering, and internal memory storage, it ensures reliable earth testing in noisy electrical environments.

Key Features:

• Stakeless Earth Resistance Testing: Measures earth resistance across a broad range from 0.001Ω to 1200Ω without auxiliary ground stakes.

• AC Leakage Current Measurement: Measures low-level AC current from 0.01mA to 20A for ground loop line monitoring.

• Simultaneous Dual Display: Displays earth resistance and current values concurrently on a digital screen.

• Advanced Noise Filtering: Features fast filtering technology to minimize strong electronic interference during field measurements.

• On-Board Data Memory: Stores up to 300 measurement datasets for field logging and reporting.

• Audible & Visual Alarms: Triggers an alarm when measured values exceed set threshold limits, accompanied by a dedicated NOISE symbol when interference current is present on the loop.

Detailed Description:

The Major Tech MT332 provides non-intrusive earth ground testing on multi-grounded electrical installations, lightning protection grids, and utility poles. By clamping around the grounding lead or busbar, it measures loop resistance and leakage current simultaneously without interrupting system continuity.

Equipped with a quick self-test function, fast noise filtering, and threshold alarm setup, the MT332 simplifies compliance testing and maintenance verification for commercial grounding networks.
