Megger DLRO-10HD Digital Low Resistance Ohmmeter

Overview

The Megger DLRO-10HD is a heavy-duty digital low resistance ohmmeter designed for measuring resistance in demanding industrial environments, including production lines, railways, and aircraft systems. Capable of delivering 10 A current for up to 60 seconds at resistances up to 250 mΩ and 1 A for resistances up to 2.5 Ω, the DLRO-10HD offers both high and low output power selection for condition diagnosis. The instrument is powered by an internal rechargeable lead-acid battery or mains supply, enabling continuous operation even with a depleted battery.

Key Features

• High and low output power selection for condition diagnosis
• 10 A output for up to 60 seconds, reducing cooling wait time
• Measurement range: 0 to 250 mΩ (at 10A), up to 2.5 Ω (at 1A)
• High input protection to 600V
• Rugged case rated IP65 (lid closed), IP54 (operational with battery)
• Five test modes: bidirectional, unidirectional, automatic, continuous, and inductive
• Rotary mode selection switch (easy operation even with gloved hands)
• Large, clear backlit LCD display (readable from distance)
• Rechargeable lead-acid battery or mains power supply
• Continuous operation even if battery is completely flat (mains powered)
• Suitable for laboratory, workshop, and field use
• Ideal for charging inductance testing due to extended test duration
