Megger DLRO10 - Digital Low Resistance Ohmmeter - 10A/2000 Ohms


The Megger DLRO10 sets the standards for low resistance measurement. The DLRO10 is a fully automatic instrument, selecting the most suitable test current up to 10A DC to measure resistance from 0.1 µOhm to 2000 Ohms, on one of seven ranges. The DLRO10 is built into a strong, lightweight case that is equally at home in the field or in the laboratory. Featuring a large, bright 4½-digit LED display, the DLRO10 is light enough to be worn around the neck and is small enough to be taken into areas that were previously too small to access.

Normally, measurements are made with forward and reverse currents to cancel the effects of any standing voltages across the test sample. To assist operator safety and ease of use, the instrument is supplied complete with a pair of duplex handspikes with 1.2 m (4 ft) leads. One of the probes is fitted with LED's which duplicate indicators on the instrument display indicating that all four contacts have been made, the presence of a high voltage across the load, and the presence of current flow while a load is discharging. A full range of test leads are also available with probes, clamps and kelvin clips.


  • Accurate results in under three seconds
  • Auto current reversal cancels standing emfs
  • Fuse protected to 600 V
  • NiMH battery reduces weight
  • 250 mW power limit (with optional override) to avoid heating the test sample
  • Automatically detects continuity in potential and current connections
  • Visible warning of high voltages present at the terminals
  • Visible warning of current flowing in the test sample
  • Multiple operating modes including fully automatic
