Dab tsi ntawm multimeter yog qhov zoo rau cov neeg siv hluav taws xob pib yuav
Multimeter yog ib qho ntawm cov cuab yeej tsim nyog rau cov neeg ua haujlwm hluav taws xob lossis cov neeg nyiam siv hluav taws xob. Kev xaiv ntawm multimeter nyob ntawm qhov xwm txheej tiag tiag. Cov haujlwm ntawm multimeters muaj nyob rau hauv txhua hom, thiab nws yog qhov zoo tshaj los xaiv ib qho uas haum rau koj.
Piv txwv li, cov phooj ywg hluav taws xob, siv lub tshuab hluav taws xob ntau nrog ntau qhov hluav taws xob AC thiab DC, cov ntaub ntawv tiv thaiv, cov ntaub ntawv qhib-tawm buzzer, thiab cov ntaub ntawv capacitance feem ntau siv. Ntev npaum li cov ntaub ntawv voltage, cov ntaub ntawv tiv thaiv, thiab cov ntaub ntawv capacitance txaus, qhov ntau yog txaus.
Yog hais tias nws yog siv rau cov hluav taws xob circuits, ntxiv rau yav dhau los tej yam kev mob yuav tsum tau raws li, kuj yuav tsum muaj ib tug triode ntsuas iav thiab ib tug kub ntsuas iav. Hauv tshwj xeeb, lub peev xwm ntsuas ntsuas iav yuav tsum ua kom tau raws li qhov xav tau ntawm kev ntsuas. Ntau lub capacitors ntawm lub rooj tsav xwm Circuit Court muaj peev xwm ntawm 1 picofarad. Yog li ntawd, qhov kev ntsuas capacitance ntau ntawm multimeter yuav tsum muaj peev xwm ntsuas cov khoom nrog lub peev xwm me me ntawm lub tshuab hluav taws xob. Qee cov multimeters yuav tsum tau ntxig tus pins capacitor rau hauv qhov ntsuas qhov ntsuas qhov chaw nres nkoj ntawm lub 'meter' txhawm rau ntsuas qhov capacitance. Qee cov multimeters tsis tas yuav tsum tau ntsaws rau hauv lub ntsuas ntsuas. Tsuas yog kho lub iav mus rau qhov ntsuas qhov ntsuas qhov ntsuas thiab siv ob txoj kev xeem. Ntsuas lub peev xwm ntawm lub capacitor ncaj qha.
Lub multimeter muaj phau ntawv ntau yam thiab tsis siv neeg ntau yam, thiab nws yog sib xws nrog phau ntawv ntau thiab tsis siv neeg ntau yam. Qhov zoo ntawm kev siv ntau yam tsis siv neeg yog tias nws tuaj yeem zam qhov kub hnyiab tawm ntawm multimeter vim qhov ntsuas tsis raug. Tau kawg, nws tus nqi siab dua li ntawm phau ntawv ntau yam multimeters. Siab, luv luv, muaj ntau hom thiab hom ntawm multimeters, thiab nws yog qhov zoo tshaj plaws los xaiv ib qho uas haum rau koj tus kheej siv.
