MEGGER 247002 Digital Low Resistance Ohmmeters

Digital Low Resistance Ohmmeters ( DLRO® ) are a family of highly accurate instruments that provide a simple, practical and reliable means of making low-resistance tests in the field. They also are ideal for production quality control. They operate on the four-wire measurement principle, thus eliminating lead and contact resistances. With basic accuracies of ± 0.25% and resolution down to 0.1 µ -ohm, they are nonetheless designed to be rugged and portable for use at the job site. A variety of optional test leads and calibration resistance standards are offered for use with DLROs. Megger DLROs require test leads, two potential and two current, to make low-resistance measurements. In addition to individual current and potential lead sets, duplex leads that combine current and potential connections in one set are offered. A variety of C-clamps, Kelvin clips, fixedpoint and helical spring-point leads are available in various lengths. Features: Single-Pak Low Range Model 247002 Provides an extra range for applications requiring 0.1 ohm resolution Features a current-reversing switch to average out voltage offset. Resolution to 0.1 µ -ohm on 599.9 µ -ohm range Standard accuracy of ± 0.25% Broad line of test leads is available to simplify and enhance data collection. Digital Readout
