Megger DLRO10X-NLS Low Resistance Ohmmeter

Overview

The Megger DLRO10X-NLS is a fully automatic low resistance ohmmeter featuring a bright LED color display and extensive onboard memory storage for up to 700 test results. It automatically selects the most suitable test current up to 10 A DC to measure resistance from 0.1 µΩ to 2000 Ω. The instrument is powered by a standard lithium ion rechargeable battery for portability or optional AC mains supply for continuous lab and production environments.

Key Features

• Fully automatic or manual measurement control with multiple modes
• Test current up to 10 A DC with auto current reversal canceling standing EMF
• Measurement range 0.1 µΩ to 2000 Ω across seven ranges
• Five measurement modes: Manual, Auto, Continuous, Inductive, Unidirectional
• Measurement speed: less than 3 seconds for forward and reverse current with average
• Bright LED color display with 250 mW power limit to avoid sample heating
• Data storage: 700 test records with 200-character note capability per result
• Real-time download of results and onboard storage with RS232 communications port
• User-selectable high and low pass limits for go-no-go testing
• Protected to 600 V with automatic continuity detection in test connections
• Lithium ion rechargeable battery with fast charge mode (2.5 hours to 90%)
• Optional AC mains power supply (90-264 V, 50/60 Hz) for lab and production line use
• Visible warning indicators for high voltage presence and current flow
