Kev ceev faj rau kev siv lub multimeter
(1) Ua ntej siv lub tshuab multimeter, "kev hloov kho tshuab xoom" yuav tsum tau ua ua ntej, uas yog, thaum tsis muaj hluav taws xob los ntsuas, ua tus pointer ntawm multimeter taw tes rau txoj hauj lwm ntawm xoom voltage lossis xoom tam sim no.
(2) Nyob rau hauv tus txheej txheem ntawm kev siv lub multimeter, koj tsis tuaj yeem kov cov hlau ntawm qhov ntsuas ntsuas nrog koj txhais tes, yog li ntawm ib sab, nws tuaj yeem ua kom qhov tseeb ntawm qhov ntsuas, thiab ntawm qhov tod tes, nws kuj tuaj yeem ua kom ntseeg tau. tus kheej kev nyab xeeb.
(3) Thaum ntsuas qee qhov hluav taws xob, koj tsis tuaj yeem hloov lub zog thaum ntsuas, tshwj xeeb tshaj yog thaum ntsuas qhov hluav taws xob siab lossis siab tam sim no, koj yuav tsum tau saib xyuas ntau dua. Txwv tsis pub, lub multimeter yuav puas. Yog tias koj xav tau hloov lub zog, koj yuav tsum txiav tawm qhov kev xeem ua ntej, thiab tom qab ntawd mus ntsuas tom qab hloov lub zog.
(4) Thaum siv multimeter, nws yuav tsum tau muab tso rau hauv kab rov tav kom tsis txhob ua yuam kev. Nyob rau tib lub sijhawm, xyuam xim kom tsis txhob cuam tshuam ntawm sab nraud magnetic teb ntawm multimeter.
(5) Tom qab siv multimeter, qhov hloov pauv yuav tsum muab tso rau hauv qhov siab tshaj plaws ntawm AC voltage. Yog tias nws tsis siv sijhawm ntev, lub roj teeb hauv lub tshuab hluav taws xob yuav tsum tau muab tshem tawm los tiv thaiv lub roj teeb los ntawm corroding lwm yam khoom hauv lub ntsuas.
