Proper Way to test transistors
I am working on ressurrecting an older HeathKit IM-110 VOM and want to test transistors in circuit. These transistors are 2n3393 NpN .... Is it correct, that in order to correctly see if there are any "opens" / shorts I'd have to live one connection off the board by desoldering ?
Can I simply take readings similar to a zener ..i.e. will show some resistance in one direction and infinite ohms in another....for example base to emitter...
Then measure with circuit energized and take a voltage from emitter to collector.. base to ground...etc...
Any way I am a bit confused and appreciate some assistance.....
Thanks
Tony
