Txheej txheem cej luam
Lub thaiv kev nyab xeeb cais nrog kev tiv thaiv hluav taws xob ntawm lub qhov hloov pauv transistor tso zis, uas cais thiab xa cov teeb liab nkag los ntawm cov neeg sib cuag hloov pauv lossis cov hloov pauv ze hauv thaj chaw txaus ntshai mus rau thaj chaw nyab xeeb nrog cov transistor tso zis los ntawm lub 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 yog siv los teeb tsa cov tswv yim thiab cov zis hauv-theem lossis rov qab tswj, nrog rau kev qhib lossis kaw cov haujlwm ceeb toom qhia txog kab txhaum. Cov khoom no xav tau lub zog hluav taws xob ywj pheej, nrog rau lub zog hluav taws xob cais, cov tswv yim, thiab cov zis terminals.
