Megger Micro-Ohm Meter (MO-2014) Ruggedized with Leads

Lutron Megger Micro-Ohm Meter, Model MO-2014 with Ruggedized Boot, Leads, and Carrying Case

Quickly check contact resistance in critical electrical connections, test for open or short windings in motors, generators, and transformers, and evaluate wire-to-wire resistance and heating elements. The integrated measurement comparator function provides fast Pass / Fail indication.

1. 4-Terminal Measurement: Ensures accurate very-low-resistance readings for components, protective conductors, lightning conductors, and welded points.
2. High Test Current: Provides up to 10A test current, ideal for measuring low resistance in the 60,000 µΩ range.
3. Dual Working Modes: Offers resistive and inductive modes (resistive mode is default) for versatile measurement conditions.
4. User-Friendly Operation: Includes a “Good/Fail” set function and a built-in buzzer for QC judgments.
5. Special Functionality: “CALCULATE” mode allows cable/wire length measurement using ohms-per-foot entry.
