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?

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 … ...

Between testing old components, measuring voltages and checking the continuity of circuits, you'll be reaching for it all the time. But there are many other applications in a 'meter, so it's ...

A multimeter and its test leads allow electrical workers to reach into an energized panel, touch live circuit components with the end of the test leads, and capture electrical readings like voltage, ...

Testing branch circuits Branch circuit wiring problems lead to more residential electrical fires than any other single cause. Hidden trouble inside a branch circuit can also lead to electrocutions and ...

Featuring built in test points with a lever disconnect switch, the WKC/TKM series of top-mounted knife edge disconnect terminal blocks allow a technician to either test or calibrate a circuit ...
