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
