Multimeter kev khiav hauj lwm cov txheej txheem thiab ceev faj rau kev siv
1. Ua ntej siv, koj yuav tsum paub txog ntau yam kev ua haujlwm ntawm lub tshuab multimeter, thiab xaiv cov iav kom raug, ntau yam thiab kuaj cov qhov (socket) raws li cov khoom raug ntsuas.
2. Thaum qhov luaj li cas ntawm cov ntaub ntawv ntsuas tsis paub, koj yuav tsum xub teem lub ntau yam hloov mus rau qhov siab tshaj plaws tus nqi, thiab tom qab ntawd hloov los ntawm ntau yam loj mus rau qhov me me, kom lub meter pointer qhia ntau tshaj 1/2 ntawm tag nrho. nplai.
3. Thaum ntsuas kev tiv thaiv, tom qab xaiv qhov tsim nyog magnification theem, kov ob qhov kev sim ua kom lub pointer point ntawm qhov chaw xoom. Yog tias tus pointer deviates los ntawm xoom txoj hauj lwm, kho qhov "zero adjustment" knob kom rov qab tus pointer mus rau xoom kom paub meej tias qhov ntsuas tau raug. . Yog tias nws tsis tuaj yeem raug xoom lossis cov duab digital teeb tsa lub tswb qis, nws yuav tsum tau kuaj xyuas lub sijhawm.
4. Thaum ntsuas qhov kev tiv thaiv ntawm ib qho hluav taws xob, lub zog hluav taws xob ntawm lub voj voog nyob rau hauv kev sim yuav tsum raug txiav tawm, thiab kev ntsuas yuav tsum tsis txhob ua thaum nws siv.
5. Thaum siv multimeter rau kev ntsuas, xyuam xim rau kev nyab xeeb ntawm tus neeg thiab cov cuab yeej ntsuas. Thaum lub sij hawm xeem, koj tsis raug tso cai kov cov hlau ib feem ntawm lub xeem cwj mem nrog koj ob txhais tes, thiab nws tsis raug tso cai hloov lub iav hloov thaum lub hwj chim yog nyob rau kom paub meej qhov kev ntsuas thiab tsis txhob muaj xwm txheej xws li hluav taws xob poob siab thiab kub kub. lub 'meter'. .

Nco ntsoov siv
1. Ua ntej siv lub tshuab multimeter, koj yuav tsum ua "txhim kho xoom xoom", uas yog, thaum tsis muaj hluav taws xob ntsuas, lub ntsuas ntsuas multimeter yuav tsum taw tes ntawm xoom voltage lossis xoom txoj haujlwm tam sim no.
2. Thaum siv lub tshuab multimeter, tsis txhob kov cov hlau ntawm cov hlau lead ntawm koj txhais tes. Qhov no tuaj yeem ua kom ntsuas qhov tseeb ntawm ib sab tes, thiab kev nyab xeeb ntawm tus kheej ntawm qhov tod tes.
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 tam sim no loj, 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 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, kev saib xyuas yuav tsum tau them nyiaj kom tsis txhob muaj kev cuam tshuam ntawm sab nraud magnetic teb ntawm multimeter.
5. Tom qab siv lub multimeter, qhov hloov pauv yuav tsum tau teem rau qhov siab tshaj plaws AC voltage ntau. 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.
