Ntsuas AC thiab DC tam sim no nrog Multimeter
1. Ua ntej ntsuas qhov tam sim no, ua ntej txiav txim siab qhov xwm txheej ntawm qhov tam sim no (AC thiab DC) thiab qhov ntau ntawm qhov tam sim no.
2. Xaiv cov cuab yeej ntsuas tsim nyog (xws li kev nyab xeeb, qhov tseeb, thiab yooj yim siv rau kev ntsuas ntawm qhov chaw) thiab ntsuas ntsuas. Tom qab xaiv cov cuab yeej ntsuas tsim nyog, yog tias koj tsis yog tus kws tshaj lij tab sis tsuas yog tus neeg nyiam, nws raug nquahu kom nyeem cov lus qhia rau kev siv.
3. Cov kauj ruam ua haujlwm dav dav:
1) Yog tias nws yog ib qho khoom siv hluav taws xob me me (xws li cov khoom siv, thiab lwm yam), koj tuaj yeem nyeem cov khoom siv rau cov lus piav qhia ntawm cov khoom siv hluav taws xob siv hluav taws xob. Qee zaum, ntu no qhia ncaj qha txog qhov tam sim no uas cov khoom siv hluav taws xob hla dhau thaum ua haujlwm hauv phau ntawv. Yog tias phau ntawv tsuas yog qhia txog kev siv hluav taws xob thiab qhov hluav taws xob, qhov tam sim no tuaj yeem suav nrog cov qauv "A=W/V". Thaum nws yog ib qho tsim nyog los ntsuas tag nrho cov tam sim no thaum ntau yam khoom siv ua haujlwm, cov khoom siv tam sim no ntawm ib tus neeg siv tau ntxiv ua ke los xam tag nrho cov tam sim no ntawm kab loj.
Yog xav tau kev ntsuas tiag tiag:
(1) Xaiv cov iav uas tsim nyog ( ntsuas tam sim no, thaj tsam ntawm cov nqi tam sim no)
(2) Tshem tawm qhov ntsuas hluav taws xob (tab sis cov khoom siv hluav taws xob thiab cov khoom thauj tsis tuaj yeem raug txiav tawm, txwv tsis pub nws yuav yog luv luv!), ntxig lub multimeter rau hauv lub voj voog (nco ntsoov tias nws txuas nrog hauv series), thiab qhov tsis kam ntawm multimeter yuav luag xoom. Qhov tam sim no ntws los ntawm multimeter yog sib npaug rau qhov tam sim no ntws los ntawm cov khoom siv hluav taws xob thiab kev thauj khoom.
2) Yog tias nws yog cov khoom siv hluav taws xob loj (ua haujlwm voltage feem ntau yog 220V txog 380V), nws raug nquahu kom siv lub clamp ammeter (multimeter). Lub hauv paus ntsiab lus yog los tsim ib qho chaw kaw electromagnetic rau ntawm txoj kab hluav taws xob, thiab qhov kev hloov pauv hauv electromagnetic teb ua rau lub tshuab hluav taws xob multimeter los tsim tam sim no. Nws muaj qhov sib npaug ntawm qhov tam sim no thiab ntsuas kab tam sim no, yog li cov kab tam sim no tuaj yeem nyeem ncaj qha hauv ammeter.
