Megger DLRO600 600 A Micro-Ohmmeter

Overview

The Megger DLRO600 is a high-current micro-ohmmeter delivering up to 600 A d.c. for low resistance testing of large circuit breakers, busbars and high-current connections. Using a four-terminal measurement technique to eliminate test-lead resistance, it measures from 0.1 µΩ to 1 Ω and stores results for reporting — built for demanding substation commissioning and maintenance.

Key features of the Megger DLRO600 micro-ohmmeter

• Up to 600 A d.c. test current, selectable from 10 A to 600 A
• Measures 0.1 µΩ to 1 Ω with 0.1 µΩ best resolution
• Four-terminal (Kelvin) technique eliminates test-lead resistance
• Large LCD with on-board alphanumeric keypad for test current and limits
• On-board memory for up to 300 test results and notes
• RS232 port for download or real-time output to a printer; mains powered

DLRO600 high-current resistance applications

The DLRO600 is used for high-current contact resistance testing of large circuit breakers, disconnectors, busbar and cable joints and earth bonds where very high test currents are needed to confirm joint integrity. Its 300-result memory and RS232 output suit documented substation and heavy-industrial maintenance work.

DLRO600 vs DLRO200

The DLRO600 delivers up to 600 A for large apparatus and busbar testing. For applications where up to 200 A is sufficient, the Megger DLRO200 offers the same four-terminal measurement in a lighter high-current instrument.
