Yuav Ua Li Cas Siv Multimeter los ntsuas qhov dej ntws tam sim no
Ib tug multimeter tuaj yeem ntsuas tsis tau tsuas yog voltage tab sis kuj to. Muaj ob txoj hauv kev los ntsuas qhov to, ib qho yog txoj kev tiv thaiv, thiab lwm yam yog txoj kev ntsuas hluav taws xob. Txawm hais tias txoj kev ua haujlwm tsis zoo lossis txoj kev siv hluav taws xob, qhov kev sojntsuam liab tau muab tso rau hauv V Ω qhov ntawm lub multimeter, thiab cov kev sojntsuam dub tau muab tso rau hauv COM qhov ntawm multimeter.
Yuav ua li cas ntsuas seb lub tshuab hluav taws xob puas xau hluav taws xob siv txoj kev tiv thaiv? Ua ntej, tua lub hwj chim ntawm cov khoom siv hluav taws xob, siv lub multimeter, thiab kho cov iav ntawm multimeter mus rau buzzer iav ntawm qhov tsis kam. Ib qho kev sojntsuam ntawm multimeter yog muab tso rau ntawm lub plhaub sab nraud ntawm cov khoom siv hluav taws xob, thiab lwm qhov kev sojntsuam yog muab tso rau ntawm qhov nyob thiab xoom xaim raws. Yog hais tias lub multimeter emissions ib lub suab, nws qhia tau hais tias cov khoom siv hluav taws xob muaj ib tug loj heev to thiab yuav tsum tau mus xyuas qhov chaw ntawm lub to.
Yog hais tias lub multimeter tsis ua suab nrov, qhov kev tiv thaiv ntau ntawm multimeter yuav tsum tau nce ib qib zuj zus kom txog thaum ntsuas tus nqi tiv thaiv. Feem ntau, tus nqi tsis kam qis dua {{0}}.38M Ω yog suav tias yog to, thiab tus nqi tsis kam siab tshaj 0.38M Ω yog suav tias tsis muaj to.
Txoj kev voltage yog siv los ntsuas qhov to ntawm cov khoom siv hluav taws xob. Kaw qhov kev hloov ntawm cov khoom siv hluav taws xob thiab pab lub multimeter hloov mus rau AC iav ntawm 700V (txhua lub tshuab hluav taws xob muaj peev xwm sib txawv, kho kom haum rau qhov siab tshaj plaws tam sim no iav). Cov hlau lead liab ntawm lub multimeter yog muab tso rau ntawm lub plhaub ntawm cov khoom siv hluav taws xob, thiab cov hlau lead dub tau muab tso rau ntawm kab xoom. Lub multimeter qhia qhov voltage, qhia cov khoom siv hluav taws xob to. Lub multimeter qhia qhov voltage li xoom, qhia tias tsis muaj qhov to.
Txoj kev ntsuas hluav taws xob muaj qee qhov kev txwv hauv kev ntsuas qhov to, vim nws tsuas tuaj yeem ntsuas qhov xau ntawm cov xaim nyob, tsis yog qhov xau ntawm xoom xaim. Yog tias muaj cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob, nws tuaj yeem cuam tshuam qhov tseeb ntawm txoj kev ntsuas hluav taws xob, yog li nws tsis pom zoo kom siv txoj kev ntsuas hluav taws xob.
