在判别出管型和基极b后,可用下列方法来判别集电极和发射极。将万用表拨在R×1K档上。用手将基极与另一管脚捏在一起(注意不要让电极直接相碰),为使测量现象明显,可将手指湿润一下,将红表笔接在与基极捏在一起的管脚上,黑表笔接另一管脚,注意观察万用表指针向右摆动的幅度。然后将两个管脚对调,重复上述测量步骤。比较两次测量中表针向右摆动的幅度,找出摆动幅度大的一次。对PNP型三极管,则将黑表笔接在与基极捏在一起的管脚上,重复上述实验,找出表针摆动幅度大的一次,对于NPN型,黑表笔接的是集电极,红表笔接的是发射极。

数据检出电路。置位端S和复位端R都接地的情况下,在C端时钟脉冲作用下,D数据端的数据(0或1)被传输至输出端Q。D端只有0或1两个数据状态,C端上升沿脉冲作用期间,D端的数据为Q端所检出。根据此原则(或满足此检测条件下),可在其时钟端人为施加“0”或“1”信号,检测Q端和D端数据传输状态,由此准确判断芯片好坏。由上述,因而对如我——一位较懒惰的检修人员来说,检测数字电路的好坏,无需研究其繁杂的时序图,也不用管它传输频率是多少和具体的传输数据是什么,电路仅为高低电平信号处理器,或仅为传输一个直流5V和直流0V的信号电路。
