PnP Tout 1 for PNP Transistor 1. Set your Analog Multi meter to Ohmmeter X1 Ohm Scale, 2. Connect the Negative Probe (Black) to Emitter and the Positive Probe (Red) to the Base. The needle should deflect to the right side, reading less than 100 ohms. 3. Now invert the probo connections to the Emitter for the Red Probe and to the Base for Black. The Needle should not deflect. If the results are the same as above, your Emitter-Base junction is OK. 4. Now we will be testing the Base-Collector junction Connect the Red probe to the Base and the Black probe to the Collector. The Needle should deflect to the right; resistance usually is not less than 100 ohms. 5. Invert the probes again, Black to the Base and the Red probe to the Collector. The Needle should not move. If results are the same as above, your Base-Collector junction is Ok. 8. Connect the probes to the Emitter and Collector (probes may be inverted) a reading above 1Kohms indicates a working transistor.
