Today’s multimeters do the same jobs as the AVOmeter, but they’re more sophisticated and can do multiple other tests as well. Depending on the model, a multimeter can tell you whether a diode ...

A multimeter is a tool that measures electrical properties like resistance, voltage, and current. It is used to test electrical components such as diodes and capacitors.

To measure the diode voltage drop, the multimeter automatically applies a small voltage across the probes and increases this voltage until the two probes are electrically connected (i.e. the diode ...

This test requires a digital multimeter with a diode check mode and can only be performed on a three-phase regulator-rectifier. Three-phase units are the most common, recognizable by the three ...
