Megger DLRO10 Digital Low Resistance Ohmmeter (Ducter), 10A, 0.1 µΩ to 2000 Ω, 4-Terminal Kelvin, with DH4-C Duplex Handspike Lead Set (1006-598)

Features

• Fully automatic Ducter™ low-resistance measurement — instrument selects the most suitable test current up to 10 A DC to measure resistance from 0.1 µΩ to 2000 Ω across seven ranges
• Accurate, repeatable results in under three seconds with basic accuracy of 0.2%
• Automatic current reversal cancels the effects of standing EMFs across the test sample for trusted readings
• Fuse protected to 600 V for added operator safety on live substation and maintenance work
• 250 mW power limit (with optional override) avoids heating the test sample during measurement
• Automatically detects continuity in both potential and current connections before starting a test
• Visible on-screen warnings for high voltages at the terminals and for current flowing in the test sample
• Large, bright 4½-digit LED display is visible under all lighting conditions
• Strong, lightweight case is equally suited to field or laboratory use — light enough to be worn around the neck for hands-free access in tight spaces
• NiMH rechargeable battery pack delivers approximately 1000 × 10 A tests per charge, with interchangeable packs and external charger for continuous testing
• Fast-charge mode reaches 90% capacity in 2.5 hours; full charge in 4 hours from 115/230 V AC or 12 V DC supply
• Supplied with DH4-C 1.5 m Duplex Connect Handspike Lead Set with quick push-and-twist interchangeable terminations
