TRANSISTOR GAIN TEST -
can be
made using an
ohmmeter and a
simple test
circuit. The principle behind this test lies in the fact that little or no current will
flow in a transistor between emitter and collector until the emitter-base
junction is forward biased. A 10 to l resistance ratio in the test between meter
readings indicates normal gain.
TRANSISTOR LEAKAGE TEST -
can be
made using an
ohmmeter by measuring
the base-emitter, base-collector, and collector-emitter forward and reverse
resistances. Each section checked will have a low-forward resistance and a
high-reverse resistance.
