Transistor tester and signal injector.
A very useful transistor tester that can also determine gain.
· Tests Transistors - locates base
leads and finds CE or BE shorts.
· Determines transistor gain.
· Produces a signal for testing audio circuits.
Use section 1 to determine the base lead and determine PNP or NPN.
Go to section 2 to determine open or shorted Collector-emitter or
base-emitter junction.
Go to section 3 to determine gain of the transistor.
Board dimensions: 4.2in x 1.1in.
