1. Plug the test leads into + and - COM sockets.
2. Set the range selector to x10 (15mA) for small size transistor, or to x1 (150mA)
for big size transistor.
3. Adjust 0
Ω
ADJ to set the pointer to zero position of the
Ω
scale.
4. Connect the transistor with the tester :
For NPN transistor, the "N" terminal of the tester is connected with the
COLLECTOR (C) of the transistor and the "P" terminal with the EMITTER
(E) of the transistor.
For PNP transistor, reverse the NPN transistor connection.
5. Read Iceo range. If the pointer is within the LEAK zone or the pointer moves
up near the full scale, the tested transistor is not good. Otherwise it is a good
transistor.
4.7 hFE (DC amplification) transistor test
1. Set the range selector to x 10.
2. Adjust 0
Ω
ADJ to adjust the pointer to zero position.
3. hFE (DC amplification) test.
4. Read the hFE scale. The value of the reading is Ic / Ib, which is the DC
amplification degree of the tested transistor.
