Megger DLRO100XB Digital Low Resistance Ohmmeter

A significant addition to the comprehensive range of Megger Low Resistance Ohmmeters, DLRO100 enables low resistance measurement, across multiple applications, in areas without access to mains power. The integral Li-Ion battery supplies a constant 100 A current for up to 200 Manual/Auto tests to enable enhanced productivity in remote locations. With a focus on user safety, advanced design features ensure the safe operation of the instrument in the most adverse conditions, including a CAT IV 600 VAC / 500 VDC safety rating in accordance with IEC61010. The rugged design, intuitive interface and IP54 (lid open) rating ensure reliability and ease of use in the most arduous of conditions.

There are three models in the series, all three models can be line powered, are rated CAT IV 600 V and can test currents from 10 to 110 A. B in the model name indicates the battery powered option (in addition to AC power).

• DLRO100 E or EB - The base model. 
• DLRO100 X or XB - The mid-range model includes all features in the basic model, with added data storage and DualGround™ testing capability.
• DLRO100 H or HB - The top-of-the-line model includes features in the E and X models, with asset tagging (enter unique asset ID's using the DLRO100 Asset Tag Windows app), Bluetooth® download and USB remote operation.

Megger DLRO100XB Comes Supplied With:

• Certificate of Test
• Quick Start Guide
• Calibration Certificate
• CD Containing User Guide
• Mains Lead
• USB Cable

A lead set is NOT included with the instrument and must be ordered as an optional accessory.

Test Modes

The Manual test mode allows the user to initiate the test procedure once the probes are in contact with the object under test. Once the TEST button is depressed the TEST lamp will illuminate and the instrument will undertake a single test to verify the resistance of the test object.

In Auto mode the user selects the desired current, connects the current test leads and as soon as the potential leads are connected a test will start automatically. To repeat a test, simply break contact with the potential probes and remake contact.

In Continuous mode the user connects the test leads and presses the TEST button, initiating the test procedure. The instrument will continue to test, updating the display after each new test cycle, until the TEST button is pressed or the test procedure times out.

Key Features:

• CAT IV 600 VAC / 500 VDC for safe operation
• Lightweight 100 A battery powered unit for portability
• High noise immunity for stable readings
• Smooth DC Output for circuit breaker testing
