Megger DLRO10 Digital Low Resistance Microhmmeter P-Type Duplex Twist Probes 1003-48 + 3m Hook Termination Leads 1003-508

Megger DLRO10 Digital Microhmmeter for High-Accuracy Low-Resistance Testing

The Megger DLRO10 Digital Microhmmeter delivers precise 10 A low-resistance measurement down to 0.1 μΩ, making it a core instrument for technicians who require stable, repeatable field performance. Designed for fast micro-ohm verification of busbar joints, switchgear contacts, grounding bonds, and battery intercell connectors, the DLRO10 applies automatic forward and reverse current to cancel thermoelectric effects and ensure reliable Kelvin four-terminal results. This configuration includes Megger P-Type Duplex Twist Probes (1003-48) and 3 m Hook Termination Leads (1003-508), offering flexibility across clamps, studs, lugs, and conductor geometries.

Why It Helps

Accurate low-resistance measurements are essential for identifying high-heat transition points, verifying mechanical and electrical joint integrity, and confirming system grounding performance. The DLRO10’s rapid 3-second stabilized readings, automatic range selection up to 10 A, and durable design make it suited for utility substations, industrial facilities, transportation systems, and aerospace bonding applications. Its Kelvin four-terminal configuration reduces lead influence, enabling more consistent micro-ohm measurement in real-world environments.

Key Highlights

• 10 A micro-ohm testing from 0.1 μΩ to 2000 Ω
• Automatic forward/reverse current cancellation for high stability
• Four-terminal Kelvin measurement for improved accuracy
• Normal, Auto, Continuous, and Inductive modes
• Bright LED display for clear visibility in field conditions
• Includes P-Type Duplex Twist Probes (1003-48)
• Includes 3 m Hook Termination Leads (1003-508)
• Supplied with hard transport case for field protection

Compatibility

This DLRO10 configuration is optimized around the included P-Type Duplex Twist Probes and 3 m Hook Termination Leads. These accessories enable four-terminal Kelvin connections on lugs, flat busbars, threaded studs, bolted joints, and grounding conductors where conventional clip-style contacts may not be suitable. Their construction supports stable, low-impedance contact necessary for 10 A testing on low-resistance components.

Applications

• Switchgear and circuit breaker contact resistance
• Busbar joint and cable lug micro-ohm testing
• Ground bonding resistance measurement
• Battery intercell connection verification
• Transformer and motor winding resistance
• Rail, aircraft, and industrial bonding
