The Megger DLRO10HD and DLRO10HDX 10 A Digital Low Resistance Ohmmeters measure resistance (0-2500 Ω, ±0.2% ± 0.2-200 μΩ) for applications like railways, motors, and welding, delivering up to 10 A (250 mΩ) or 1 A (2.5 Ω) with ±10% current accuracy.
Five test modes—normal, automatic, continuous, unidirectional, and inductive—support diverse needs, with bidirectional testing to cancel thermal EMFs. The DLRO10HDX adds 200-record storage and USB data transfer to PowerDB. Rated CAT III 300 V with an optional terminal cover, the 6.7 kg, IP65-rated (closed) units operate in -10 °C to 50 °C, powered by a 7 Ah lead acid battery (>1000 3-second auto tests, 8-hour charge) or mains (100-240 V). Features include a backlit LCD, rotary switches, noise detection (<1% error at 100 mV 50/60 Hz), and auto power off.
The rugged case has a removable lid and lead pouch. The kit includes DH4-C 1.5 m or KC1 3 m leads (or none), mains lead (US/UK/EU), and, for DLRO10HDX, a USB cable. Optional terminal cover and lead sets enhance safety and versatility. Backed by a one-year warranty, these ohmmeters ensure reliable, high-current testing.
