How to Test a Transistor & Diode | Electronics Notes

Germanium ones that have a much higher level of reverse leakage current may easily show a small deflection if the meter is set to a high ohms range. This simple analogue multimeter test of a diode is very useful because it gives a very quick indication of whether the diode is basically operational.
