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 multimeter
Thaum ntsuas cov khoom siv hluav taws xob ntawm txhua qhov hluav taws xob nrog lub tshuab hluav taws xob, koj yuav tsum xub xyuas lub xeev ntawm multimeter ua ntej koj lub stylus kov cov khoom siv hluav taws xob. Piv txwv li, thaum ntsuas DC voltage, koj yuav tsum ntaus lub DC voltage iav. Yog tias koj tsis paub tias qhov hluav taws xob Circuit Court yog dab tsi, ua ntej ntawm tag nrho cov, ntaus lub iav mus rau lub siab tshaj plaws iav. Yog tias koj ntsuas AC voltage, koj yuav tsum ntaus cov iav cuam tshuam ntawm AC. Yog tias koj tsis paub qhov voltage, koj yuav tsum ntaus lub iav siab tshaj plaws los ntsuas nws ua ntej. Tom qab ncav cuag lub siab tshaj plaws iav los ntsuas cov ntaub ntawv, kho lub iav raws li xav tau rau kev ntsuas kom raug. Nco ntsoov txhua tus neeg saib xyuas lub xeev ntawm lub multimeter kom 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 kev cuam tshuam luv luv thiab cov khoom hlawv. Yog li ntawd, ua ntej ntsuas ib yam dab tsi, peb yuav tsum tsim ib tug cwj pwm ntawm kev cim, uas yog, peb yuav tsum tau saib lub iav txheej xwm ntawm lub multimeter thiab xyuas kom meej tias nws yog lawm ua ntej ntsuas.
Ua ntej ntawm tag nrho cov, cia peb teb cov lus nug tseem ceeb: yuav ua li cas kom tsis txhob luv luv Circuit Court thaum ntsuas qhov voltage ntawm txhua kab ntawm lub rooj tsavxwm Circuit Court nrog multimeter
1, ntse li ua tau multimeter nib.
Thaum kuv tseem nyob hauv tsev kawm ntawv, kuv tau ua raws li kuv tus tij laug laus, uas yog, kuv nyiam txhuam cov hlau pem hauv ntej ntawm tag nrho kuv cov multimeters. Lub ntse ntse multimeter tuaj yeem tiv tauj thaj tsam ntawm lub rooj tsav xwm Circuit Court me me li sai tau, thiab kev ntsuas ntawm qee thaj chaw me me tuaj yeem tiv thaiv lub hau kom tuab heev kom tsis txhob kov cov neeg nyob ib sab. Txoj kev no, yog tias koj ntshai tias tus cwj mem polished yuav yooj yim oxidize.
2. Nrhiav cov cwj mem dub ntxiv thiab hloov lawv mus rau hauv cov kab nuv ntses.
Nrhiav ib khub cwj mem ntxiv, txiav cov dub ib tug thiab nrhiav ib tug crocodile clip los welding rau tom qab siv. Tau kawg, yog tias koj tsis xav ua koj tus kheej, koj tuaj yeem yuav cov cwj mem liab thiab dub.
Txhawm rau ntsuas qhov voltage ntawm lub rooj tsav xwm Circuit Court, thawj zaug txiav txim seb qhov yuav tsum tau ntsuas yog DC voltage lossis AC voltage. Yog hais tias nws yog DC voltage, ua ntej teem lub iav ntawm lub multimeter thiab ntaus lub iav rau DC voltage ntsuas. Tom qab ntawd, muab ib tug cwj mem dub rau ntawm ib txhais tes thiab ib tug cwj mem liab nyob rau lwm qhov. Cov cwj mem dub yog tag nrho cov av hauv av, thiab sim nrhiav qhov chaw hauv av uas yooj yim rau muab tso thiab kov kom ze li sai tau. Feem ntau, qhov taw tes hauv av yog lub rooj tsav xwm loj heev. Tus cwj mem liab raug cais los ntsuas qhov ntsuas hluav taws xob. Nyob rau lub sijhawm no, qhov polished ntau dua cov lus qhia multimeter, qhov yooj yim dua nws yog los ntsuas qee qhov zoo thaj tsam circuits. Yog tias nws tsis yooj yim rau ob txhais tes los tuav cov cwj mem sib cais, cov cwj mem nrog cov hlua khi peb tau hais ua ntej tuaj yeem ua ke rau lub sijhawm no. Txuas cov cwj mem dub nrog cov hlua khi hlua khi, thiab tus pas nuv ntses khi lawv mus rau qhov chaw hauv av ntawm lub rooj tsavxwm, kom cov cwj mem liab tuaj yeem ntsuas tag nrho DC Circuit Court ntawm qhov xav tau.
Yog tias koj ntsib ib qho tshwj xeeb nyias nyias thiab tsis muaj tus cwj mem ntse, koj tuaj yeem pom ib rab koob xaws thiab kho nws ntawm tus cwj mem nrog nyias tooj liab hlau tsis muaj rwb thaiv tsev, uas tuaj yeem ntsuas tau.
