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 ...

Digital multimeters (DMM), once called voltmeters, have been described as the tape measure for engineers in the new millennium. With electronics and electrical circuits included in almost every ...

Diodes with the wrong markings create extra work for engineers and serve as a reminder that one should never assume anything when troubleshooting design problems Years ago I ran a small electronics ...
