Meter check of a transistor
For PNP Transistors
1. Set multimeter to Ohmmeter Ohm Scale.
2. Connect the Negative Probe (Black) to Emitter and the Positive Probe (Red) to the Base(R=R1).
3. Now invert the probe connections to the Emitter for the Red Probe and to the Base for Black. R = “OL”.If this works, your Emitter-Base junction is OK.
4. Now test the Base-Collector junction. Connect the Red probe to the Base and the Black probe to the Collector (R=R2).
5. Invert the probes again, Black to the Base and the Red probe to the Collector. R = “OL”.If this works, your Base-Collector junction is Ok.
6. Connect the probes to the Emitter and Collector (probes may be inverted), R = “OL”indicates a working transistor.

Transistor - Wikipedia https://en.wikipedia.org/wiki/Transistor A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. Semiconductor device · Bipolar junction transistor · Field-effect transistor · Amplifier Transistors - learn.sparkfun.com https://learn.sparkfun.com/tutorials/transistors Transistors are fundamentally three-terminal devices. On a bi-polar junction transistor (BJT), those pins are labeled collector (C), base (B), and emitter (E). The circuit symbols for both the NPN and PNP BJT are below: The only difference between an NPN and PNP is the direction of the arrow on the emitter.
