The test modes are NPN and PNP.
- Connect a collector of Tr. to pin A, a base to pin B and an emitter to pin G.
- Pressing F3 key at this condition sets the voltage between collector and emitter to the
value, which is close to 1.0V, varying the electric current that flows in the base of Tr.
- In case user varies the Bias voltage, the standard value (or test value) becomes larger
and smaller.
- Setting the standard value as close as 1.0V is profitable to distinguish a defect.

我的资料是这样的,但实际上NPN,PNP测试不太稳定,不过我作的试验如漏插,偏脚,反插都可测,只有插成同种类型的TR无法测出。
大家有好的测试方法请帖出来,让我学学
:) :) 如果我的资料有错误,天哪!我可犯了大错了:( :( :(
