Txheej txheem cej luam
Lub thaiv kev nyab xeeb cais nrog lub qhov hluav taws xob nkag mus rau hauv transistor, uas cais thiab xa cov teeb liab nkag los ntawm cov neeg sib txuas lus lossis qhov sib thooj cov hloov pauv hauv thaj chaw txaus ntshai mus rau thaj chaw nyab xeeb nrog cov transistor tso zis los ntawm kev thaiv kev nyab xeeb. Kev kuaj pom qhov txhaum ntawm kab yog ua tiav los ntawm LED nyob rau sab saum toj ntawm lub module. Lub dial switch ntawm lub module siv los teeb tsa cov tswv yim thiab cov zis hauv-theem lossis rov qab tswj, nrog rau kom ua kom muaj peev xwm los yog lov tes taw qhov kev ua haujlwm ntawm lub tswb ceeb toom txog kab txhaum.
Cov khoom no xav tau kev muab hluav taws xob ywj pheej, nrog rau kev rho tawm hluav taws xob cov terminals ntawm cov khoom siv, cov khoom siv nkag, thiab cov khoom siv tso zis.
