Megger DLRO100 Series of Digital Low Resistance Micro-Ohmmeters

The Megger DLRO100 series offers a range of digital low resistance micro-ohmmeters tailored for demanding testing scenarios. These instruments provide a test current of up to 100 A DC, facilitating accurate resistance measurements from 0.1 μΩ to 1.999 Ω with a resolution of 0.1 μΩ. The series includes various models, each equipped with features to enhance testing efficiency and safety.

The DLRO100 series is powered by an integral Li-ion battery, delivering a constant 100 A current for up to 200 manual or automatic tests on a single charge. This battery-powered design enables testing in locations without access to mains power, offering flexibility for field operations. Additionally, the instruments feature a smooth DC output, minimizing ripple and ensuring stable readings during circuit breaker testing.

Safety is a paramount consideration in the design of the DLRO100 series. The instruments are rated for CAT IV 600 V / 500 VDC operation, providing protection against electrical hazards. The DualGround™ feature allows for testing with both sides of the equipment under test grounded, enhancing safety during measurements. Furthermore, the IP54-rated enclosure offers protection against dust and moisture, ensuring reliable performance in various environmental conditions.

User-friendly interfaces, including large, clear LCD displays with backlighting, facilitate easy operation in all lighting conditions. The instruments also offer optional Bluetooth connectivity for wireless communication and remote control capabilities via USB, streamlining data management and analysis.
