Dab tsi yog qhov laj thawj ntawm kev siv lub tshuab ntsuas ntau los ntsuas qhov ohm ntau ntawm cov khoom siv hauv tsev, qee qhov txuas thiab qee qhov tsis yog?
Yog tias koj ntsuas cov khoom siv hluav taws xob xws li hluav taws xob lossis hluav taws xob hluav taws xob, lossis lub rooj teeb uas siv lub teeb pom kev zoo, thaum lub qhov hloov tau qhib, qhov kev tawm tsam ntawm ob qhov kawg ntawm lub ntsuas plug yuav tsum yog li 100 ohms. Thaum ntsuas ob qhov kawg ntawm cov plugs ntawm TVs, tub yees, tshuab ntxhua khaub ncaws, thiab lwm yam., qhov kev tiv thaiv qhov tseem ceeb yog sib txawv, vim hais tias cov plugs ntawm txhua yam khoom siv hluav taws xob sib txawv ntawm lawv cov hluav taws xob hauv hluav taws xob, thiab tso saib cov nqi sib txawv.
Tom qab tus kheej tau ntsib lub tshuab ntxhua khaub ncaws thaum lub tshuab hloov pauv, qhov kev tiv thaiv ntsuas ntawm ob qhov kawg ntawm lub ntsaws yog li 200 ohms rau lub cev muaj zog hauv lub tshuab ntxhua khaub ncaws.
Qee cov khoom siv hauv tsev xws li LCD TVs thiab cov tub yees muaj cov nqi tiv thaiv ze rau qhov tsis muaj hnub kawg hauv kev siv ib txwm.
Raws li cov saum toj no, siv ib tug multimeter los ntsuas lub on-off ntawm hluav taws xob plug los txiav txim seb cov khoom siv hluav taws xob zoo los yog phem tsis haum rau tag nrho cov khoom siv hluav taws xob, thiab multimeter tsis yog ib tug panacea. Tsuas yog tsim nyog rau qee yam khoom siv hluav taws xob, xws li hluav taws xob hluav taws xob, hluav taws xob, hluav taws xob, hluav taws xob, hluav taws xob soldering irons, lub cev muaj zog coils, incandescent teeb, thiab lwm yam.
Ua ntej ntsuas cov khoom siv hauv tsev, koj yuav tsum nkag siab txog daim duab kos duab ntawm cov khoom siv, tshwj xeeb tshaj yog cov khoom siv hluav taws xob. Qee tus siv lub tshuab hloov pauv kom nqis thiab kho tus taw tes yuav hloov pauv thaum ntsuas nrog lub ntsuas ntsuas, thiab qee qhov siv lub voj voog hloov lossis lwm lub voj voog, thiab tus taw tes yuav tsis tas hloov. Tsis tas li ntawd, lub Circuit Court breaker multimeter yuav tsis muaj qhov taw qhia. Yog li ntawd, ua ntej ntsuas, sib piv cov duab kos lossis qhib cov khoom siv hluav taws xob los xyuas cov qauv hauv Circuit Court, kom tsis txhob muaj kev txiav txim siab.
Txoj kev siv hluav taws xob ntawm ntau yam khoom siv hauv tsev sib txawv, thiab lub zog kuj sib txawv, yog li qhov ntsuas qhov ntsuas kuj sib txawv. Yog tias nws yog lub zog hloov hluav taws xob, nws muaj kev tiv thaiv diode pib sab hauv, yog li qhov ntsuas tsis tuaj yeem ntsuas.
