A battery-operated volt-ohm-meter (VOM), or multitester, is a simple, relatively inexpensive testing device that's well worth acquiring if you plan to do electrical repairs. A VOM can tell you whether ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

A multimeter is an easy prospect, right? Back in the day you could make one fairly easily with a decent panel meter and a set of precision resistors, and now a digital one can be had for throwaway ...

Modern digital multimeters (DMMs) are user-friendly, accurate, and safe — when used correctly! Reading voltage is simple, but measurements must be properly interpreted. With a clamp-on DMM, accurate ...

Snap-on’s new EECT900 Multi-Probe Ultra features a circuit tester and digital multimeter in one handheld device for testing AC and DC voltage, resistance, and amperage. A rear-facing LCD navigation ...

The Fnirsi LC1020E LCR meter is an affordable yet powerful tool for measuring resistance, capacitance, and inductance with ...

Multimeters are indispensable tools when working on electronics. It’s almost impossible to build any but the most basic of circuits without one to test and troubleshoot potential issues, and they make ...
