Outfitted with all the features and functions of the DLRO200-EN, Megger’s DLRO200-115 Digital Low Resistance Ohmmeter has the addition of a filtered output.
Ideal for applications that require a smooth DC current, the extra output filtering lessens mains frequency ripple and is able to drive 200A through 11mΩ total current loop resistance. More still, the filtered output eradicates magnetic transients that, if left in the test circuit, may inductively trip a breaker’s control.
