This micro ohmmeter has a display length of 60,000 counts and auto averaging of forward and reverse measurement removes thermal emf differences.

The DO7Plus micro ohmmeter has built in rechargeable batteries which will provide up to 1 hour of continuous use at 10A, and up to 20 hours at all other ranges.
