Dab tsi ntawm multimeter yog qhov zoo rau cov pib siv hluav taws xob?
Multimeter yog ib qho ntawm cov cuab yeej tseem ceeb rau cov neeg ua haujlwm hluav taws xob lossis cov neeg nyiam hluav taws xob. Xaiv ib lub multimeter yuav tsum ua raws li qhov xwm txheej tiag tiag. Cov haujlwm ntawm multimeter muaj nyob hauv txhua hom, thiab xaiv qhov uas haum rau tus kheej yog qhov zoo tshaj plaws.
Piv txwv li, electricians feem ntau siv multimeters rau AC thiab DC voltage, tsis kam, on/off buzzer, thiab capacitor nqis. Tsuav qhov voltage, tsis kam, capacitor nqis, thiab ntau yam txaus, lawv txaus.
Yog tias nws yog siv rau cov khoom siv hluav taws xob, ntxiv rau kev ua kom tau raws li cov xwm txheej dhau los, kuj yuav tsum muaj peb theem transistor ntsuas hom thiab hom ntsuas kub. Tshwj xeeb tshaj yog nyob rau hauv hom kev ntsuas capacitance, nws yog ib qho tsim nyog los ua kom tau raws li qhov xav tau ntawm kev ntsuas. Ntau lub capacitors ntawm Circuit Court boards muaj peev xwm ntawm 1 picofarad, yog li qhov ntsuas qhov ntsuas qhov ntsuas ntawm lub tshuab hluav taws xob yuav tsum muaj peev xwm ntsuas cov khoom uas muaj peev xwm me me ntawm cov khoom siv hluav taws xob. Qee cov multimeters ntsuas capacitance los ntawm kev ntxig cov pins ntawm lub capacitor rau hauv qhov chaw ntsuas qhov ntsuas qhov ntsuas ntawm qhov ntsuas, thaum lwm tus tsis tas yuav tsum tau muab tso rau hauv lub ntsuas ntsuas. Tsuas yog kho cov iav mus rau qhov ntsuas qhov ntsuas qhov ntsuas thiab siv ob qhov kev sojntsuam ncaj qha los ntsuas lub peev xwm.
Multimeters tuaj nyob rau hauv ob qho tib si phau ntawv thiab tsis siv neeg ntau yam, thiab yog sib xws nrog ib leeg. Qhov zoo ntawm kev siv ntau yam tsis siv neeg yog tias nws tuaj yeem tiv thaiv lub multimeter los ntawm kev kub hnyiab tawm vim qhov ntsuas tsis raug. Tau kawg, nws tus nqi siab dua li ntawm phau ntawv ntau yam multimeters. Nyob rau hauv luv luv, muaj ntau hom thiab cov qauv ntawm multimeters, thiab xaiv ib tug uas suits koj tus kheej yog qhov zoo tshaj plaws.
