Product Overview: Megger DLRO2X Ducter Low Resistance Ohmmeter 2A

Megger DLRO2X Ducter Low Resistance Ohmmeter 2A

Noise Rejection mode with Confidence MeterTM (DLRO2X)
„ Manual and auto save results for export to USB (DLRO2X)
„ ‘Difference Meter’ for quick data comparisons
„ Use very long test leads at 1 A using dedicated test mode
„ Safely test the resistance of inductive loads at 1 A
„ <600 V active protection against inadvertent live connections without blowing a fuse
„ Ideal for outdoor use with protection against dust and moisture to IP54
„ Industry standard safety rated at CAT III 600 V/CAT IV 300
The DLRO2 series are tough, hand-held 2 A low resistance ohmmeters. They are designed to provide fast, accurate, repeatable measurements, even in electrically noisy locations. The DLRO2 is the latest in a long line of instruments to proudly display the Ducter™ brand, the Ducter™ testers being as well- known and relied upon as Megger insulation resistance testers.
For the utility or industrial user, a high level of safety is provided with a CAT III 600 V/CAT IV 300 V rating to IEC61010. In addition, the instrument can protect itself from inadvertent connections to up to 600 V without blowing a fuse, thereby avoiding essential time lost due to repairs or finding a replacement fuse.
When working outside, the IP54 rating ensures that neither rain nor dust will prevent testing.
The DLRO2 measures low resistance values across a wide range of applications, from railways and aircraft, to the resistance of industry components.
Applications requiring long test leads are not a problem for the DLRO2 as it has a dedicated long lead test to optimize the output. The long test lead function is able to provide up to 1 A of test current into 3.2 ohms resistance. This makes the DLRO2, with its optional cable reel test leads, ideal for testing wind turbine and avionic lightning protection applications.
To allow testing of smaller inductive loads, the DLRO2 can apply 1 A for at least 15 seconds, made possible by the high-capacity built-in rechargeable batteries, together with a separate inductive load function. The batteries can be fully  recharged in 2.5 hours, minimizing downtime.
Note: The DLRO2 is not ATEX/intrinsically safe rated and must not be used in explosive gas environments
FEATURES AND BENEFITS
Easily select functions using the rotary dial.
Option to run the test in bidirectional mode or in unidirectional mode to save time and battery power.
The ability to view 3 results on the screen at any time makes it ideal for 3-phase systems.
Overcome the effects of standing EMF voltages using the bidirectional test mode. Forward and reverse results can be viewed on the secondary display.
For stability of results, the instrument will warn you when electrical noise, or noise from poor clip/probe connections, is present.
Keeps testing as long as you can, with as many as 500 x 2 A – 3 second tests from a full charge.
Supplied with compact CAT III 600 V/CAT IV 300 V rated kelvin clip test leads.
Noise rejection range with Confidence Meter TM (DLRO2X only)

EXAMPLE APPLICATIONS
Aviation – Lightning protection testing measuring mΩ resistance between receptors, wing tip to wing tip etc., using long test leads. Optional long cable reel test leads are available, can be used for assembly of components, interconnection of equipment, repair, and maintenance.
Wind turbines – Lightning protection, measuring mΩ resistance between wing tip to ground connection at base using long test leads. Optional long cable reel test leads are available.
Rail, tram and underground – Rolling stock and infrastructure, track high current joints, signalling systems.
Marine – Power wiring systems, protection systems, ship- to-shore bonding, cathode protection system testing, and
cable laying applications.
Oil and gas pipelines – Bonding between welded joints and grounding systems.
Automotive and EV – Battery connections, weld quality, crimped connections quality, assembly robot welding cables.
Cable manufacturers – Quality control, cable length.
Component manufacturers – Quality control.
Space exploration and engineering – Structural metal to metal, ground network metal to metal, carbon fibre to metal, carbon fibre to carbon fibre.
Data centres – During electrical installation of main panel, generator, and UPS systems. Verification of protective device contact resistance, busbar parallel feeds, busbar lapped joints, optimum resistance over torque, and cable lug to busbar connections. During maintenance using trending data for all aspects of the above, verification after repair.
