If we tests transistor from middle pin, assuming it base, to another pin gets Open Loop (OL), would it indicate a defect/broken transistor if test it to the next pin gets some sound voltages (more or less 1 V)?
hi,
OK,
If you get an o/c reading between the Base and either the Collector or Emitter it could mean the transistor is faulty,
Which type of transistor are you testing.?
E
The base to emitter junction and base to collector junction in a BJT transistor both act like diodes, When you use a diode tester, check them both in both directions by intrchanging the test leads. In one direct it will read around 0.7V. In the other it will real OL on a good transistor
