Siv ib lub multimeter los ntsuas cov dej ntws tam sim no
Lub multimeter tsis tuaj yeem ntsuas qhov hluav taws xob nkaus xwb tab sis kuj tseem xau tib lub sijhawm. Muaj ob txoj hauv kev los ntsuas qhov to, ib qho yog txoj kev tiv thaiv, lwm qhov yog txoj kev siv hluav taws xob, tsis hais txoj kev tiv thaiv lossis txoj kev siv hluav taws xob, tus cwj mem liab tau muab tso rau hauv VΩ qhov ntawm lub multimeter, thiab tus cwj mem dub tau muab tso rau hauv COM qhov. ntawm lub multimeter.
Txoj kev tiv thaiv yuav ua li cas los ntsuas seb cov khoom siv hluav taws xob puas, ua ntej ntawm tag nrho, tua lub zog ntawm cov khoom siv hluav taws xob, siv cov multimeter, ua ntej pab lub multimeter iav rau qhov tsis kam ntawm beeping iav. Ib qho ntawm cov cwj mem ntawm lub multimeter so ntawm lub plhaub ntawm cov khoom siv hluav taws xob, thiab lwm tus cwj mem so ntawm qhov hluav taws xob thiab xoom xaim, yog tias lub multimeter ua lub suab nrov, nws txhais tau hais tias cov khoom siv hluav taws xob xau hluav taws xob tiag tiag, thiab qhov chaw nyob. ntawm cov leakage yuav tsum tau kuaj xyuas.
Yog hais tias lub multimeter tsis suab, los tsa lub multimeter kuj iav qib los ntawm theem, kom txog rau thaum qhov ntsuas ntawm qhov kev tiv thaiv tus nqi, cov kev cai dav dav ntawm tus nqi kuj tsawg dua {{0}}}.38M ohms rau cov xau. , siab tshaj 0.38M ohms rau qhov tsis muaj dej.
Txoj kev ntsuas hluav taws xob los ntsuas cov khoom siv hluav taws xob kaw, kaw qhov hloov ntawm cov khoom siv hluav taws xob, pab lub multimeter iav rau AC cov ntaub ntawv 700V iav (txhua lub multimeter iav yuav txawv, kho rau cov ntaub ntawv tam sim no siab tshaj iav), multimeter tus cwj mem liab ntawm lub plhaub ntawm cov khoom siv hluav taws xob, tus cwj mem dub ntawm lub xoom kab, lub multimeter qhia qhov voltage, qhia tias cov khoom siv hluav taws xob xau, lub multimeter qhia tau hais tias qhov hluav taws xob yog xoom, qhia tias tsis muaj qhov to.
Txoj kev ntsuas hluav taws xob ntawm kev ntsuas qhov xau muaj qee qhov kev txwv, tsuas yog ntsuas qhov hluav taws xob xaim, thiab tsis tuaj yeem ntsuas qhov xoom kab xau. Yog tias muaj cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob, nws tseem yuav cuam tshuam qhov tseeb ntawm txoj kev siv hluav taws xob, yog li nws tsis pom zoo kom siv cov qauv hluav taws xob.
