Features

Resolution to 0.1μΩ on 599.9μΩ range
Standard accuracy of ±0.25%
Kelvin-type, four-wire measurement
- Eliminates lead & contact resistance errors
Digital readout with automatic zero circuit
- Eliminates field test inaccuracies

The Megger 247002 DLRO micro-ohmmeter are a family of highly accurate instruments that provide a simple, practical and reliable means of making low-resistance tests in the field. They also are ideal for production quality control. They operate on the four-wire measurement principle, thus eliminating lead and contact resistances. With basic accuracy of ±0.25% and resolution down to 0.1 μΩ, they are nonetheless designed to be rugged and portable for use at the job site. A variety of optional test leads and calibration resistance standards are offered for use with DLROs.

This model provides an extra range, 0 to 599.9 μΩ, for applications requiring 0.1 μΩ resolution. It also features a current-reversing switch to average out any voltage offset in the test sample. Captive wing nuts are also standard.

Operation is simple: just connect the leads, turn the instrument on and read the measurement directly from the digital LED display. No warm-up is required.

Applications for the Megger 247002 DLRO:

Switch and circuit breaker contacts
Transformers and generators
Motor windings
Busbar and other joints
Aircraft, rail and pipe bonds
Cable splices, welds and fuses
Metal alloys
Graphite electrodes and other composites
Wire and cable
