Hello Friends,
This Video about How to Check Transistor Using Digital Multimeter | PNP & NPN Transistor | Electronic Engineering
I showed you in a previous video how to check a transistor with an analog multimeter. So in today's video I will show you how to check a transistor with a digital multimeter.
Transistor Testing Procedure
There are five steps to test a transistor in an electric circuit. The steps involve connecting the:
Base to the emitter
Base to collector
Emitter to base
Collector to base
Collector to emitter
For an NPN transistor, the emitter is grounded with the collector at a voltage that the base controls. For a PNP design, the collector is grounded with the emitter at a voltage.
These methods of testing tell you if a transistor is shorted or opened for bipolar transistors. The transistor may still fluctuate in its performance, within a specific range, just as a result of how it was engineered.
To begin the transistor testing procedure, remove the transistor from the circuit itself. Take your multimeter and connect the positive lead to the base of the transistor. Then, connect the negative lead to the transistor's emitter.
At this point, check the reading on your multimeter. An NPN transistor that functions properly should show a voltage drop between 0.45 and 0.9 volts, and a PNP transistor should show an "over limit" message. Any signs on the multimeter that differ from these values could indicate bad transistor symptoms.
Then, connect the negative lead of the multimeter to the collector of the transistor; this is the "base to collector" step. As was the case with the previous step, an NPN transistor should have a voltage drop between 0.45 and 0.9 volts while a PNP one should be over the limit.
