Megger DLRO10HD Low Resistance Ohmmeter

Key Features

• High or low output power selection for condition diagnosis
• Rechargeable battery or line power supply, continuous operation, even with dead battery
• 10 A for 60 seconds, less time waiting to cool, great for charging inductance
• High input protection to 600 V, inadvertent connection to line or UPS voltage will not blow a fuse
• Heavy duty case: IP 65 lid closed, IP54 operational (battery operation only)
• Rotary switch selects one of five test modes, including auto start on connection, giving ease of use
  

Overview

The Megger DLRO10HD low resistance tester can output up to 10 Amps and is built into a tough case that provides an IP65 ingress protection rating when closed and an IP54 rating when the instrument is in use and operating from battery power. This Megger low resistance test and measuring instrument incorporates a large backlit liquid crystal display that can be read from distance its rotary switch controls can be operated with gloved hands.

With 0.1 micro-ohm resolution, 0.2 per cent basic accuracy and a dedicated mode for use with inductive loads, the Megger DLRO10HD is suitable for applications such as checking welded joint quality, verifying winding resistance in large motors and transformers, performance of lightning protection bonds and aircraft structures.

To provide maximum versatility, this test set not only features high compliance but also offers user-selectable high or low power ranges.

The high power <25W ranges (measuring up to 250milliohm at 10A or 2.5ohm at 1A) are ideal for heating a weakness or charging inductive loads.

The low power ranges are power limited to 250 mW for applications where it is desirable to avoid heating the item under test.
