Yuav ua li cas siv multimeter los ntsuas thiab ntsuas AC voltage thiab xoom nyob xaim
Yuav ua li cas ntsuas AC voltage nrog multimeter
1. Kev ntsuas ntawm AC voltage
1. Ntxig cov hlau kuaj dub rau hauv COM jack, thiab cov hlau kuaj liab rau hauv V / Ω jack.
2. Muab qhov hloov pauv ua haujlwm nyob rau hauv qhov ntau ntawm AC voltage range V ~, thiab txuas tus cwj mem mus rau lub hwj huam mov los yog thauj khoom mus kuaj.
3. Thaum ntsuas AC voltage, tsis muaj polarity zaub.
4. Txawm hais tias ntsuas AC lossis DC voltage, ua tib zoo saib xyuas kev nyab xeeb ntawm tus kheej thiab tsis txhob kov cov hlau ntawm cov khoom siv lead ua casually.
Siv qhov ntsuas ntawm AC 220V ua piv txwv: tig qhov hloov mus rau qhov xav tau qhov ntsuas hluav taws xob thaum ntsuas (thaum ntsuas AC 220V, qhov hloov yuav tsum tig mus rau AC 750V).
Thaum ntsuas, tus cwj mem xeem yuav tsum tau txuas nrog tib lub voj voog nyob rau hauv kev sim. Yog tias koj tsis paub qhov ntau ntawm qhov voltage los ntsuas, koj tuaj yeem siv qhov kev txwv loj dua kom tau txais qhov kwv yees tus nqi ua ntej, thiab tom qab ntawd tig mus rau qhov ntsuas qhov ntsuas.
2. Cov lus qhia ua haujlwm
1. Xaiv lub AC voltage iav rau qhov ntau. Thaum tsis paub qhov voltage ntau, nws yuav tsum tau xaiv los ntawm qhov siab tshaj plaws.
2. Lub 'meter' yuav tsum tau txuas mus rau qhov sib npaug ntawm ob qho kawg ntawm lub voj voog lossis cov khoom siv hauv kev sim.
3. Ntsuas cov kauj ruam ntawm AC voltage
Kauj Ruam 1: Qhib lub hwj chim hloov ntawm lub digital multimeter, thiab tig lub iav ntawm multimeter mus rau AC voltage ntau ntawm 750V.
Kauj Ruam 2: Qhib lub hwj chim hloov hauv Circuit Court.
Kauj Ruam 3: Ntsuas qhov voltage ntawm cov ntsiab lus 1-2 thiab sau cov ntawv nyeem. Qhov ntsuas voltage yog 220V.
Kauj ruam 4: Tig lub iav ntawm multimeter mus rau AC voltage ntau ntawm 20V, ntsuas qhov voltage ntawm cov ntsiab lus 3-4, 4-5, thiab 6-7, thiab sau cov ntawv nyeem.
4. Cov teeb meem xav tau kev saib xyuas
1. Yog tsis paub qhov ntsuas qhov voltage. Teem lub zog hloov mus rau qhov siab tshaj plaws thiab maj mam txo.
2. Yog hais tias cov zaub tsuas yog qhia tau hais tias "1.", nws txhais tau hais tias qhov ntau me me dhau lawm, thiab cov kev ua haujlwm hloov yuav tsum tau teem rau ntau dua.
3. "" txhais tau tias tsis ntsuas voltages siab tshaj 1000V. Nws yog qhov ua tau los tso saib cov nqi hluav taws xob ntau dua, tab sis muaj qhov txaus ntshai ntawm kev puas tsuaj rau cov kab hluav taws xob sab hauv.
4. Thaum ntsuas qhov hluav taws xob siab, ua tib zoo saib xyuas kom tsis txhob muaj hluav taws xob poob siab.
