The Megger DLRO10 bring new standards to low resistance measurement. A fully automatic instrument, selecting the most suitable test current, up to 10A dc to measure resistance from 0.1µΩ to 2000Ω 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. Light enough to be worn around the neck, they are small enough to be taken into areas which were previously too small to access. The Megger DLRO 10 uses a large, bright 4-1/2-digit LED display. A full range of test leads is available with probes, clamps and Kelvin clips.

The Megger DLRO10 is powered by a rechargeable Nickel Metal Hydride (NiMH) battery, which permits one thousand 10 Amp tests to be completed on a single charge. The battery module contains intelligent circuitry, which prevents damage to the battery from overcharging, and a battery state indicator. A removable lid that is hinged at the back and held closed by magnetic catches covers the top panel. This lid may be removed if required by opening fully and snapping out of its hinges.


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.
