ENGINEERING ARCHITECTURE & DESIGN
True RMS Conversion: Minimizes waveform distortion errors generated by variable speed drives, switched-mode power supplies, and automated production controls.
Integrated NCV Sensor: Facilitates rapid live-circuit verification at the jaw tip prior to physical conductor engagement, enhancing operational safety protocols.
Robust Clamp Geometry: The 28 mm jaw profile enables single-handed cable isolation within tightly bundled distribution boards and motor control centers.
Protective Circuit Design: Full-scale overload protection rated to 600V across voltage, resistance, and continuity testing modes prevents component failure during inadvertent operator error.

INDUSTRIAL APPLICATION
The UT201+ solves critical diagnostic challenges in facility power distribution systems containing non-linear loads. In industrial setups where standard average-responding clamp meters miscalculate distorted waveforms, the True RMS capability of this unit provides precise current telemetry. It is utilized by maintenance engineers for monitoring phase balance, verifying motor running current on industrial pumps and conveyors, and diagnosing low-voltage control panel circuitry without breaking active conductors.

PROCUREMENT & COMPLIANCE
Technical Compatibility: Standard 4 mm shrouded safety terminals ensure full compatibility with standard industrial test lead sets, fused probes, and busbar alligator clips.
Original Engineering: Direct UNI-T factory production standard with verified calibration consistency and serialized tracking.
Lead Time: Stock configurations ship within 24 to 48 hours for maintenance, repair, and operations (MRO) provisioning and fleet procurement.
