580 Micro-Ohmmeter | KeithleyThe Model 580 Micro-ohmmeter combines high accuracy, resolution, and sensitivity with three special capabilities that make micro-ohm measurements easier and more versatile than ever: When measuring contact and connector resistances, it is important not to puncture oxides and films that may have formed. The Model 580 ensures this dry-circuit condition by clamping the open-circuit test voltage to 20mV on the 200m, 2, and 20 ranges when the 20mV MAX button is pressed.
