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?

The voltage in Figure 4was measured at a zener-diode current of 2.8 mA. Figure 4 Measure the voltage across a zener diode with a digital multimeter. You can use the circuits in figures 2 and 3 to test ...

However, the circuit described here performs a simple go/no-go test on these diodes while limiting forward current and reverse voltage to safe levels (see the figure).

When checking and verifying capacitors, inductors, diodes, bipolar transistors, and cables, the gamut of test methods can range from those used to confirm a defective component ...
