Overview

The Megger DLRO100X is a 100 A micro-ohmmeter that adds internal memory and USB download to the DLRO100 range’s high-current low resistance testing. It measures from 0.1 µΩ to 1.999 Ω at up to 100 A, giving substation and industrial teams a rugged instrument that both tests and records results for reporting.

Key features of the Megger DLRO100X micro-ohmmeter

Up to 100 A d.c. test current for high-current contact resistance testing
Measures 0.1 µΩ to 1.999 Ω with 0.1 µΩ resolution and ±(0.2% + 0.2 µΩ) accuracy
Internal memory (up to 220 records) with USB download
Manual, Auto and Continuous test modes
Large backlit LCD for use in variable lighting
CAT IV 600 V AC / 500 V DC safety; IP65 (lid closed) / IP54 (lid open) rugged case

DLRO100X high-current resistance applications

The DLRO100X is used for testing circuit-breaker contacts, busbar and cable joints, earth bonds and switchgear connections where high test current plus on-board record storage is required. Its memory and USB download make it well suited to commissioning and maintenance programmes that need documented results.
