Yuav ua li cas yog cov kev ntsuas tam sim no nrog ib tug multimeter
1. Lub iav txoj hauj lwm yuav tsum ua raws li hom kev ntsuas tam sim no. Xaiv cov iav kom raug raws li AC / DC hom tam sim no koj xav ntsuas, nrog AC sib haum rau AC iav thiab DC sib haum rau DC iav;
2. Xaiv qhov tsim nyog, txwv tsis pub nws yuav ua rau lub multimeter hlawv. Yog tias koj tsis paub qhov loj ntawm qhov ntsuas tam sim no, koj yuav tsum xaiv qhov siab tshaj plaws. Piv txwv li, digital multimeter nrog 20 ampere ntau yam tuaj yeem ntsuas qhov tam sim no ntawm 4.4 kilowatts ntawm hluav taws xob;
3. Txuas lub multimeter nyob rau hauv series mus rau cov hlau nyob ntawm cov khoom siv hluav taws xob. Ua li no, thawj kauj ruam yog tua hluav taws xob hloov. Qhov thib ob kauj ruam yog kom tshem tawm lub ntsaws thiab txuas lub 'meter' nyob rau hauv series; Qhov thib peb kauj ruam yog ntsaws rau hauv lub plug thiab ces kaw qhov hloov. Hauv qhov no, kev nyeem ntawv ntawm multimeter yog ob qho tib si tus nqi xav tau.
Ceeb Toom: Siv cov qauv no los ntsuas qhov tam sim no hauv cov khoom siv hluav taws xob siab yog qhov txaus ntshai heev thiab tuaj yeem hlawv cov 'meter' yooj yim. Nws raug nquahu kom siv lub clamp hom ammeter. Txoj kev no, nws muaj kev nyab xeeb thiab yooj yim rau kev khiav lag luam.
Kev ceev faj rau kev siv
1. Ua ntej siv multimeter, nws yog ib qho tsim nyog yuav tsum tau ua "kev hloov kho xoom xoom", uas txhais tau hais tias thaum tsis muaj hluav taws xob ntsuas, lub ntsuas ntsuas multimeter yuav tsum tau muab tso rau ntawm xoom voltage lossis xoom tam sim no.
2. Thaum lub sij hawm siv multimeter, tsis txhob kov cov hlau ntawm qhov kev sojntsuam nrog koj txhais tes. Qhov no ua kom qhov ntsuas qhov tseeb thiab kev nyab xeeb ntawm tus kheej.
3. Thaum ntsuas qee qhov hluav taws xob, nws tsis pom zoo kom hloov cov iav ib txhij, tshwj xeeb tshaj yog thaum ntsuas qhov hluav taws xob siab lossis siab tam sim no. Txwv tsis pub, nws yuav ua rau muaj kev puas tsuaj rau lub multimeter. Yog tias koj xav tau hloov lub zog, koj yuav tsum xub txiav qhov kev sojntsuam thiab tom qab ntawd ntsuas tom qab hloov lub zog.
4. Thaum siv 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. Yog tias 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.
