Some transistors won’t test. Some go directly into a Self test mode when trying to test a trans. Some transistors I know are good, the tester can’t read them, “No, Unknow or Damaged” is the message. Are there certain types of transistors that can’t be tested? And what is the deal with the self test going on?
Yes that is the device. I’m not sure I understand, I’ve tried PNP and NPN transistors using all three connections. So are you saying that is not correct? Should I only be using 2 connections?
