Yuav ua li cas kom tsis txhob luv luv Circuit Court los ntawm kev ntsuas qhov voltage ntawm txhua kab ntawm Circuit Court board nrog ib tug multimeter
Thaum ntsuas cov khoom siv hluav taws xob hauv Circuit Court nrog lub multimeter, koj yuav tsum xub xyuas cov xwm txheej ntawm lub tshuab hluav taws xob ua ntej koj qhov kev xeem coj mus kov cov khoom siv hluav taws xob. Piv txwv li, yog tias koj ntsuas DC voltage, koj yuav tsum hloov mus rau lub iav ntawm DC voltage. Loj npaum li cas, thawj zaug yog ntaus lub iav kom siab tshaj iav. Yog tias koj ntsuas AC voltage, koj yuav tsum hloov mus rau cov khoom siv rau AC. Yog tias koj tsis paub qhov voltage, koj yuav tsum xub hloov mus rau lub iav siab tshaj plaws los ntsuas. Tom qab tig mus rau lub siab tshaj plaws iav thiab ntsuas cov ntaub ntawv, kho cov iav raws li xav tau rau kev ntsuas kom raug. Kev ceeb toom txhua tus kom kuaj xyuas cov xwm txheej ntawm multimeter yog txhawm rau tiv thaiv qee tus neeg los ntawm kev ntsuas qhov hluav taws xob ncaj qha thaum lub multimeter nyob rau hauv qhov kev tiv thaiv lossis qhov muaj peev xwm, uas yuav ua rau muaj peev xwm ntawm luv luv Circuit Court thiab hlawv cov khoom. Yog li ntawd, ua ntej ntsuas ib yam dab tsi, koj yuav tsum txhim kho tus cwj pwm ntawm tus lej, uas yog, koj yuav tsum kuaj xyuas cov xwm txheej ntawm lub tshuab multimeter, thiab tom qab ntawd ntsuas tom qab paub tseeb tias nws yog lawm.
Ua ntej tshaj plaws, cia peb teb cov lus nug tseem ceeb ntawm cov ncauj lus hauv qab no: yuav ua li cas kom tsis txhob luv luv Circuit Court los ntawm kev ntsuas qhov voltage ntawm txhua kab ntawm lub rooj tsav xwm hauv Circuit Court nrog multimeter.
1. Ib tug multimeter taub kom ntse li sai tau
Thaum kuv kawm thiab tseem nyob hauv tsev kawm ntawv, kuv ua raws li kuv tus kwv tij, uas yog, kuv nyiam tias cov hlau pem hauv ntej ntawm tag nrho kuv cov multimeter yog polished heev. Lub ntse ntse multimeter tuaj yeem kov lub rooj tsav xwm Circuit Court me me li sai tau. Rau kev ntsuas ntawm qee thaj chaw me me thaj tsam, nws tuaj yeem tiv thaiv tus cwj mem los ntawm qhov tuab heev kom tsis txhob kov cov neeg nyob ib sab.
2. Nrhiav cov cwj mem dub ntxiv thiab hloov lawv mus rau hauv cov hlua khi
Nrhiav ib khub ntawm cov kev xeem ntxiv, txiav cov hlau lead kuaj dub, qhov kawg ntawm tes cwj mem, thiab nrhiav ib qho hlua khi hlua khi rau nws rau qhov khoom seem. 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 Circuit Court, thawj zaug txiav txim siab seb qhov twg ntawm lub rooj tsav xwm yuav tsum ntsuas yog DC voltage lossis AC voltage. Yog hais tias nws yog DC voltage, ua ntej teem lub iav ntawm lub multimeter mus rau lub iav ntawm DC voltage ntsuas, thiab ces coj ib tug dub cwj mem nyob rau hauv ib tes thiab lwm yam, coj tus cwj mem liab, thiab tus cwj mem dub yog lub grounding davhlau ya nyob twg. Sim nrhiav qhov chaw hauv av uas yooj yim muab thiab kov kom ze li sai tau. Feem ntau, qhov taw tes hauv av yog lub rooj tsav xwm loj loj. Tus cwj mem liab raug muab cais los ntsuas lub voj voog kom ntsuas. Lub sij hawm no, lub sharper lub ntsis ntawm lub multimeter yog, qhov yooj yim dua nws yog los ntsuas ib co nplua chip tivthaiv circuits. Yog tias ob txhais tes tsis yooj yim los tuav qhov kev xeem coj sib cais, raws li peb tau hais ua ntej, qhov kev xeem seem coj nrog cov hlua khi tuaj yeem tuaj yeem siv tau rau lub sijhawm no, txuas cov kev xeem dub coj nrog cov khej clips, thiab khi cov hlua khi rau hauv Circuit Court. lub rooj tsavxwm. Ntawm qhov taw tes hauv av, cov hlau kuaj liab tuaj yeem 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 pom ib rab koob xaws thiab qhwv lub koob xaws ntawm tus cwj mem ntawm qhov ntsuas tus cwj mem nrog nyias tooj liab hlau tsis muaj rwb thaiv tsev, uas tuaj yeem ntsuas tau. .
Qee yam yuav tsum tau them sai sai rau thaum ntsuas AC voltage nrog multimeter
Thaum peb siv multimeter los ntsuas qhov voltage, ntau zaus, qhov voltage ntawm AC mains yuav ntsuas. Thaum ntsuas AC voltage, ua ntej ntawm tag nrho cov, nco ntsoov xyuas cov iav ntawm multimeter. Tsuas yog thaum lub iav yog qhov tseeb peb tuaj yeem pib ntsuas.
Ua ntej lub hwj chim qhib, sim siv lub pas nrig clip txhawm rau txhawm rau ntsuas qhov taw tes ntawm AC voltage Circuit Court, tom qab ntawd tig lub hwj chim, thiab tom qab ntawd siv lwm txhais tes los ntsuas qhov ntsuas liab los ntsuas ntau cov ntsiab lus hauv Circuit Court.
Yog tias tsis muaj kab laug sab, thaum koj yuav tsum ntsuas, yog tias qhov hluav taws xob AC tsis paub meej tias nws puas yog qhov tsis tshua muaj hluav taws xob lossis qhov hluav taws xob siab, thov ua tib zoo saib xyuas ob qho kev xeem coj nrog ib txhais tes los ntsuas, ib yam li siv chopsticks los ntsuas qhov ntsuas. AC mains voltage Circuit Court.
Qhov kev ua haujlwm no yog ua kom muaj kev nyab xeeb ntau li ntau tau. Yog hais tias ob txhais tes txhua tus ua ib qho kev xeem coj mus rau kev ntsuas, nyob rau hauv cov ntaub ntawv ntawm qhov kev ntsuam xyuas cov hlau lead xau thiab tawg los ntawm ob txhais tes thiab tau txais hluav taws xob shock, txoj hauj lwm ntawm ob txhais tes yog lub plawv, uas yog heev txaus ntshai.
Qhov kev ua haujlwm no yog qhov tsim nyog heev. Ntau tus neeg ua haujlwm paub tias feem ntau ntawm lawv tau siv hluav taws xob los ntawm 220V AC. Kuv tus kheej tau hluav taws xob. Kuv yuam kev kov AC Circuit Court thaum kho lub TV xim. Hmoov zoo, nws tau ua tiav nrog ib txhais tes. .
Txawm hais tias ntsuas DC lossis AC circuits, yog tias koj xav tiv thaiv kev sib tsoo luv luv kom ntau li ntau tau, cais cov kev xeem liab thiab xim dub kom deb li deb tau, thiab qhov kawg ntawm cov hlau lead yuav tsum kov qhov ntsuas qhov ntsuas ntawm lub voj voog ntsug. .
