Cov teeb meem xav tau kev saib xyuas thaum ntsuas qhov voltage nrog multimeter
(1) Lub multimeter yuav tsum "tso kho kho tshuab" ua ntej siv. Ua li no, taw tes lub multimeter tus taw tes rau xoom voltage lossis xoom tam sim no thaum tsis muaj hluav taws xob ntsuas.
(2) Thaum siv lub multimeter, tsis txhob kov cov hlau ntawm cov hlau lead ntawm koj txhais tes. Los ntawm kev ua qhov no, koj tuaj yeem paub tseeb tias qhov ntsuas qhov raug thiab koj tus kheej kev nyab xeeb.
(3) Nws tsis tuaj yeem hloov lub zog thaum ntsuas qhov tshwj xeeb ntawm hluav taws xob; yuav tsum tau saib xyuas ntxiv thaum ntsuas qhov hluav taws xob siab lossis siab tam sim no. Lub multimeter yuav puas lawm. Yog tias koj xav tau hloov lub zog, tshem tawm qhov kev sim ua ntej, tom qab ntawd hloov lub zog, thiab ntsuas dua.
(4) Txhawm rau tiv thaiv kev ua yuam kev, lub multimeter yuav tsum tau siv kab rov tav. Nyob rau tib lub sijhawm, nws yog ib qho tseem ceeb uas yuav tsum khaws cov khoom sib nqus sab nraud los ntawm kev cuam tshuam cov multimeter.
(5) Kev hloov pauv yuav tsum tau teem rau qhov siab tshaj AC voltage theem tom qab siv multimeter lawm. Lub multimeter lub roj teeb yuav tsum tau muab tshem tawm yog tias nws tsis tau siv ib ntus kom tsis txhob muaj roj teeb corroding lwm qhov ntawm lub ntsuas.
