How to test a transistor using a digital Multimeter

Easy way to test a transistor using a digital Multimeter. In summary, to determine what type of transistor is by swapping positive and negative probes until you get 2 forward bias voltage reading for example 1 positive probe on one pin and another two pin is on negative probe then it is an NPN transistor. To determine the which pin is collector, emitter and base: Emitter = forward bias voltage is higher than collector pin Collector = lower forward bias voltage compared to emitter pin Base = reference probe for both two junctions in forward bias
