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 ohms they are nonetheless designed to be rugged and portable for use at the job site.
The 247010-4 is the same as 247000-5 except with built-in line operated power supply. AC line operation only - no batteries.
