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.

Key Features:

CAT IV 600 V AC / 500 V DC for safe operation
Lightweight 100 A battery-powered unit for portability
High noise immunity for stable readings
Smooth DC Output for circuit breaker testing
IP54 for protection against dust and moisture whilst testing
Save, download and delete results (100XB/HB variants)
Remote operation, Bluetooth® & asset/result tagging (100HB variants)

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.

History of ‘Ducter’ testing For over 100 years the ‘Ducter test’ has been used to describe a simple test for measuring very low contact resistances and “Ducter”, which is still used as a trade mark, was the name originally given to the low resistance ohmmeter manufactured by Megger. The name Ducter was registered by Megger in June 1908 and ‘Ducter’ has since become the industry standard.

Application

The need for accurate low-resistance measurement is well known and very diverse. Typical applications include:
Utilities & Service Contractors – commissioning new installations & regular maintenance testing of

Switchgear and circuit breaker contact resistance
Busbar and cable joints
Wire and cable resistance
Lightning conductor bonding

Original Equipment Manufacturer – detecting manufacturing defects

Production test of circuit breakers – contacts & joints
Production test of high voltage switchgear
Production test of welded joints & connections

Transport – manufacturing & maintenance

Railway rolling stock ground connections & manufactured joints
Railway lines & conductor rails – commissioning & maintenance
Aircraft frame bonds and static control circuits
