Siv lub multimeter los ntsuas qhov voltage ntawm txhua kab ntawm lub rooj tsavxwm Circuit Court kom tsis txhob muaj luv luv Circuit Court
Kev ntsuas cov khoom siv hluav taws xob hauv Circuit Court nrog lub rooj, hauv koj tus cwj mem tsis kov cov khoom siv hluav taws xob hauv hluav taws xob ua ntej, yuav tsum xub xyuas cov xwm txheej ntawm lub tshuab hluav taws xob, piv txwv li, koj ntsuas DC voltage, nco ntsoov ntaus DC voltage iav, yog tias koj tsis paub tias qhov hluav taws xob Circuit Court loj npaum li cas, thawj qhov yog ntaus lub iav mus rau lub iav siab tshaj plaws. Yog tias koj ntsuas AC voltage, koj yuav tsum ntaus cov iav AC cuam tshuam, yog tias koj tsis paub qhov loj ntawm qhov voltage, tab sis kuj yog thawj zaug ntaus lub iav siab tshaj plaws los ntsuas. Tom qab ntsuas cov ntaub ntawv nyob rau hauv lub siab tshaj plaws txoj hauj lwm, kho txoj hauj lwm raws li qhov yuav tsum tau ua kom tiav kev ntsuas qhov tseeb. Nco ntsoov txhua tus txheeb xyuas qhov xwm txheej ntawm lub multimeter yog tiv thaiv qee tus neeg yuav nyob rau hauv multimeter yog qhov tsis kam lossis cov ntaub ntawv capacitance ncaj qha los ntsuas qhov voltage, uas yuav ua rau luv luv Circuit Court hlawv tej yam ua tau. Yog li ua ntej ntsuas ib yam dab tsi, peb yuav tsum txhim kho ntau tus cwj pwm yog kom saib xyuas cov xwm txheej ntawm multimeter lub iav, paub tseeb tias tsis muaj qhov yuam kev ua ntej ntsuas.
Ua ntej tshaj plaws, los teb cov lus nug ntawm cov ntsiab lus: yuav ua li cas kom tsis txhob luv luv-circuit multimeter los ntsuas lub Circuit Court board ntawm kab voltage
1, raws li ntse li ua tau multimeter taub
Hauv kuv qhov kev nyeem ntawv tseem nyob hauv tsev kawm ntawv, kuv ua raws li kuv tus tij laug tus cwj pwm, uas yog, kuv nyiam bar tag nrho lawv cov multimeter cwj mem hlau pem hauv ntej kawg yog polished heev, ntse multimeter taub hau, tuaj yeem ua me me li sai tau hu rau lub rooj tsav xwm hauv cheeb tsam. , rau qee qhov chaw me me ntawm thaj chaw ntsuas ntsuas tuaj yeem tiv thaiv qhov ntxeev ntawm tus cwj mem yog tuab heev uas ua rau muaj kev sib tsoo ntawm cov neeg nyob ib sab. Yog li ntawd yog tias koj ntshai ntawm polishing lub meter mem yog ib qho yooj yim rau oxidise, tam sim no muaj kev lag luam tau xav txog, muaj cov lus qhia tshwj xeeb kub-plated meter mem rau muag.
2, nrhiav cov cwj mem dub ntxiv, cov cwj mem dub hloov mus rau hauv cov hlua khi
Nrhiav ib nkawm cwj mem ntxiv, tus cwj mem dub, qhov kawg ntawm tes tuav tus cwj mem, txiav, nrhiav ib tug crocodile clip los txuas rau, spare. Ntawm chav kawm, yog tias koj tsis xav ua koj tus kheej, ces koj tuaj yeem yuav npaj-ua, liab thiab dub cwjmem muaj.
Ntsuas qhov hluav taws xob ntawm lub rooj tsav xwm hauv Circuit Court, thawj zaug txiav txim rau ib feem ntawm lub rooj tsav xwm Circuit Court yuav tsum ntsuas yog DC voltage lossis AC voltage, yog tias nws yog DC voltage, ua ntej ntawm tag nrho cov, lub multimeter lub iav teeb tsa, ntaus lub DC voltage ntsuas iav, thiab Tom qab ntawd ib txhais tes coj tus cwj mem dub hauv ib txhais tes coj tus cwj mem liab, tus cwj mem dub yog hauv av, kom ze li sai tau kom pom yooj yim rau kev sib cuag nrog cov ntsiab lus hauv av, qhov dav dav hauv av ntawm lub rooj tsav xwm Circuit Court kuj loj. . Liab cwj mem thiab ces cais los ntsuas lub Circuit Court uas yuav tsum tau ntsuas. Thaum lub sij hawm no, qhov ntau sharply polished multimeter taub, ntsuas ib co ntawm cov zoo thaj Cheebtsam Circuit Court, yooj yim dua. Yog tias ob txhais tes tsis yooj yim los nqa tus cwj mem sib cais, lub sijhawm no peb tau hais ua ntej, kev tsim cov khoom seem nrog cov hlua khi ntawm tus cwj mem nyob rau lub sijhawm no tuaj yeem ua ke, tus cwj mem dub nrog cov kab nuv ntses txuas nrog cov kab nuv ntses mus rau hauv. Circuit board nyob rau hauv av, tus cwj mem liab tuaj yeem ntsuas tau raws li tag nrho DC Circuit Court.
Yog tias koj ntsib ib qho tshwj xeeb nyias nyias, thiab tsis muaj qhov ntse ntse txaus, koj tuaj yeem nrhiav tau ib rab koob xaws, tsis muaj rwb thaiv tsev ntawm nyias tooj liab hlau rau xaws rab koob winding tsau rau hauv tus cwj mem taub ntawm tus cwj mem, yog li ntawd kuj tuaj yeem ntsuas. .
