Megger’s DLRO10X 1006-600 Digital Low Resistance Ohmmeter offers all the benefits of their DLRO10 1006-598, plus several new efficient features.
In addition to the measurement modes of the DLRO10 1006-598, the DLRO10X 1006-600 has an Unidirectional Measurement Mode which applies a current in only one direction, inhibiting any standing emfs to be negated, speeding up the measurement process. Not only are the forward and reverse measurements shown, the DLRO10X 1006-600 presents the average of the two measurements on the vast backlit LCD display.
Users can manually select the test current with the ohmmeter’s menu system, controlled by a two-axis paddle. Likewise, users can download in real time or take advantage of the onboard storage for up to 700 sets of results.
