Kev ceev faj rau kev siv multimeter
(1) Ua ntej siv lub 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, tsis txhob kov cov hlau ib feem ntawm lub xeem txhuas nrog koj txhais tes, yog li ntawd nyob rau hauv ib tes, qhov tseeb ntawm kev ntsuas yuav tau guaranteed, thiab ntawm qhov tod tes, tus kheej kev nyab xeeb muaj peev xwm. kuj yuav lav.
(3) Thaum ntsuas qee qhov hluav taws xob, nws tsis tuaj yeem hloov lub zog thaum ntsuas, tshwj xeeb tshaj yog thaum ntsuas qhov hluav taws xob siab lossis tam sim no loj, yuav tsum tau them nyiaj ntau dua. Txwv tsis pub, lub multimeter yuav raug puas tsuaj. Yog tias koj xav tau hloov lub zog, koj yuav tsum txiav tawm qhov kev xeem ua ntej, thiab tom qab ntawd ntsuas tom qab hloov lub zog.
(4) Thaum siv lub multimeter, nws yuav tsum tau muab tso rau kab rov tav kom tsis txhob ua yuam kev. Nyob rau tib lub sijhawm, nws tseem yuav tsum tau zam kom tsis txhob muaj kev cuam tshuam ntawm sab nraud magnetic teb ntawm lub 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.
