Yuav ua li cas kom tsis txhob luv luv Circuit Court: ntsuas qhov voltage ntawm txhua kab ntawm lub rooj tsavxwm nrog ib tug multimeter.
Ib lub multimeter ntsuas txhua qhov hluav taws xob hauv hluav taws xob. Ua ntej koj qhov kev xeem coj tuaj rau hauv kev sib cuag nrog cov khoom siv hluav taws xob hauv hluav taws xob, koj yuav tsum xub xyuas cov xwm txheej ntawm multimeter. Piv txwv li, yog tias koj ntsuas DC voltage, koj yuav tsum teem nws mus rau DC voltage theem. Yog tias koj tsis paub tias qhov hluav taws xob Circuit Court yog dab tsi. Loj npaum li cas, ua ntej hloov lub iav mus rau lub iav siab tshaj plaws. Yog tias koj ntsuas AC voltage, koj yuav tsum teeb tsa rau qib AC cuam tshuam. Yog tias koj tsis paub qhov voltage, koj yuav tsum xub teem nws mus rau theem siab tshaj plaws los ntsuas. Tom qab ntsuas cov ntaub ntawv los ntawm kev teeb tsa rau lub iav siab tshaj plaws, kho cov iav raws li qhov xav tau rau kev ntsuas kom raug. Kuv ceeb toom rau txhua tus kom saib xyuas cov xwm txheej ntawm multimeter tiv thaiv qee tus neeg los ntawm kev ntsuas qhov hluav taws xob ncaj qha thaum lub multimeter yog qhov resistor lossis capacitor, uas yuav ua rau luv luv thiab hlawv ib yam dab tsi. Yog li ntawd, ua ntej ntsuas ib yam dab tsi, koj yuav tsum tsim ib tug cwj pwm, uas yog mus xyuas lub iav raws li txoj cai ntawm lub multimeter thiab paub meej tias nws yog lawm ua ntej ntsuas.
Ua ntej, cia peb teb cov lus nug nram qab no: Yuav ua li cas ib tug multimeter ntsuas qhov voltage ntawm txhua kab ntawm lub rooj tsavxwm Circuit Court kom tsis txhob luv circuits?
1. Lub sharpest tau multimeter ntsis
Thaum kuv tseem nyob hauv tsev kawm ntawv, kuv ua raws li kuv tus tij laug laus, uas yog, kuv nyiam txhuam cov hlau pem hauv ntej ntawm tag nrho kuv cov cwj mem multimeter sharply. Lub tswv yim ntse multimeter cwj mem tuaj yeem tiv tauj lub rooj tsav xwm Circuit Court me me li sai tau. Rau qee qhov chaw me me nti, kev ntsuas tuaj yeem tiv thaiv tus cwj mem los ntawm qhov tuab heev thiab ua rau kov cov neeg nyob ib puag ncig. Nyob rau hauv txoj kev no, yog tias koj ntshai tias polished watch cwj mem yog nquag oxidation, qee cov tub lag luam tam sim no tau xav txog nws thiab muag tshwj xeeb kub-plated watch cwj mem.
2. Nrhiav cov cwj mem dub ntxiv thiab hloov lawv mus rau hauv cov kab nuv ntses
Nrhiav ib khub ntawm cov kev xeem ntxiv, txiav tawm cov hlau lead kuaj dub, qhov kawg uas tuav tus cwj mem, thiab nrhiav ib qho hlua khi hlua khi rau nws siv tom qab siv. Tau kawg, yog tias koj tsis xav ua koj tus kheej, koj tuaj yeem yuav cov khoom npaj ua tiav, suav nrog cov cwj mem liab thiab dub.
Txhawm rau ntsuas qhov hluav taws xob ntawm lub rooj tsav xwm hauv Circuit Court, ua ntej txiav txim siab seb qhov twg ntawm lub rooj tsav xwm yuav tsum ntsuas yog DC voltage lossis AC voltage. Yog tias nws yog DC voltage, thawj zaug teeb lub multimeter rau DC voltage ntsuas ntau, thiab tom qab ntawd tuav tus cwj mem dub ntawm ib txhais tes thiab lwm qhov ntawm tes. Siv tus cwj mem liab thiab tus cwj mem dub yog ob qho tib si hauv av. Sim nrhiav qhov chaw hauv av kom ze li sai tau uas yooj yim rau kev sib cuag nrog. Feem ntau, qhov taw tes hauv av yog nyob rau ntawm lub rooj tsav xwm loj loj. Tus cwj mem liab raug muab cais los ntsuas lub voj voog uas yuav tsum tau ntsuas. Lub sij hawm no, lub sharper lub multimeter cwj mem taub yog, qhov yooj yim dua nws yuav yog los ntsuas ib co nplua chip tivthaiv circuits. Yog tias nws tsis yooj yim los tuav qhov kev xeem coj sib cais nrog ob txhais tes, raws li peb tau hais dhau los, qhov kev sim npaj ua nrog cov kab nuv ntses tuaj yeem tuaj yeem siv tau rau lub sijhawm no. Txuas cov kev xeem dub coj nrog cov kab nuv ntses, thiab muab cov hlua khi hlua khi rau ntawm lub rooj tsavxwm. Ntawm qhov taw tes hauv av, cov hlau kuaj liab tuaj yeem siv los ntsuas tag nrho DC Circuit Court ntawm qhov xav tau.
Yog tias koj ntsib ib qho kev sib tw tshwj xeeb thiab tsis muaj qhov ntse txaus ntsuas tus cwj mem, koj tuaj yeem nrhiav tau ib rab koob xaws thiab siv ib lub xov tooj uas tsis muaj insulated nyias nyias los qhwv rab koob nyob ib ncig ntawm qhov kawg ntawm tus cwj mem xeem, uas tuaj yeem ntsuas tau.
