The Megger DLRO2 Ducter Low Resistance Ohmmeter is a handheld, 2 A tester for precise measurements (1 μΩ to 2000 Ω, ±1% ± 2 digits bidirectional) across applications like aviation, wind turbines, rail, and data centres. It offers normal, inductive (1 A, auto-stop), and fast/long lead (1 A, up to 4 Ω) modes, with test currents from 1 mA to 2 A (±10%).
The Difference Meter simplifies repetitive testing by comparing results to a reference, displaying percentage changes visually. Safety features include CATIII 600 V/CATIV 300 V rating, 600 V live protection without fuses, and IP54 dust/moisture resistance. Weighing 905 g, it operates in 0 °C to 50 °C, powered by 6x NiMH batteries (>1000 2 A tests, 4-hour charge) or AA alkalines.
The LCD shows three results, with noise/poor connection warnings and configurable backlight. The kit includes 2 m Kelvin clip/probe leads, 240 V charger, batteries, USB stick with user guide, hanging strap, and soft pouch. Optional long cable reel leads support wind turbine and avionic testing. Backed by a one-year warranty, the DLRO2 ensures reliable, repeatable low resistance testing.
