The Megger DLRO10x Digital Low Resistance Ohmmeter is a fully automatic instruments, selecting the most suitable test current up to 10 A d.c. to measure resistance from 0.1 μΩ to 2000 Ω, on one of seven ranges.
For users who desire more control over the measurement process, DLRO10X uses a menu system controlled by a two-axis paddle to allow the user to manually select the maximum test current.
DLRO10X also adds real time download of results and on board storage for later download to a PC.
