About Digital Low Resistance Micro-Ohmmeter- DLRO2X

The Digital Low Resistance Micro-Ohmmeter DLRO2X (Megger) is a compact yet powerful instrument designed for accurate low-resistance measurement in electrical equipment. Built for demanding field and industrial environments, it uses the 4-wire Kelvin measurement technique to eliminate lead and contact resistance errors, ensuring highly reliable results.

Unlike entry-level models, the DLRO2X delivers higher test current capability up to 2 A with advanced noise rejection, making it ideal for precise testing of switchgear contacts, busbars, cable joints, bonds, and grounding connections. Its rugged construction and ergonomic design allow dependable operation in both workshop and on-site applications. Battery operation further enhances portability, enabling uninterrupted testing without external power sources.

Key Features

Advanced 4-wire Kelvin measurement for high accuracy
Low-resistance measurement from micro-ohms to kilo-ohms
Up to 2 A test current for reliable contact resistance testing
Rugged, compact, and field-ready design
Simple operation with clear digital display
Battery-powered for portable field use

Applications

Switchgear and circuit breaker contact resistance testing
Busbar and bonding resistance measurement
Cable joint and termination verification
Earthing and grounding continuity checks
Maintenance testing of industrial and commercial electrical systems

Reliable and Accurate Low-Resistance Measurements

The DLRO2X delivers fast and accurate readings with a test range from 0.1 to 2000, resolution of 0.1, and an accuracy of 0.2% of reading plus two digits. The auto current reversal function minimizes errors due to thermal EMFs, and the data hold feature allows for efficient capturing of results.

User-Friendly Portable Design

Weighing only 1 kg and housed in an IP54-rated enclosure, the Micro-Ohmmeter is easy to carry and withstands challenging environments. Its handheld form, manual push-button and rotary dial controls, and instant response times make it ideal for field technicians who value both speed and portability.

Enhanced Data Management and Safety

Store up to 700 test results in the internal memory for easy access later. Safety is paramount with fused terminal input protection and compliance to IEC 61010 standards. Overload conditions are clearly notified on the display, helping prevent damage and ensuring user confidence.

FAQ's of Digital Low Resistance Micro-Ohmmeter- DLRO2X:

Q: How do I operate the DLRO2X Micro-Ohmmeter for a resistance test?

A: Simply connect the supplied Kelvin clamps to the circuit or specimen under test, set your desired range using the push button or rotary dial controls, and read the measurement from the large LCD display. The unit's manual operation ensures precise user control over each test.

Q: What safety features are incorporated in the DLRO2X?

A: The DLRO2X provides input protection with fused terminals to safeguard against overloads. It complies with IEC 61010 safety standards and displays clear overload indications on the screen, ensuring both the device and user are protected during operation.
