Txoj kev siv kom raug thiab kev saib xyuas yooj yim ntawm multimeter
Multimeters tau dav siv hauv kev sim xyaum qhia thiab kev saib xyuas cov cuab yeej. Kab lus no qhia txog cov kev siv kom raug thiab cov cai ntawm multimeters, nrog rau kev ceev faj hauv kev siv.
Muaj ntau hom qauv ntawm multimeter, thiab cov txheej txheem ntawm cov pob qhov rooj thiab cov keyboards ntawm lub vaj huam sib luag sib txawv. Yog li ntawd, ua ntej siv lub multimeter, ib tug yuav tsum ua tib zoo to taub thiab paub txog lub zog ntawm txhua yam, thiab nyob rau tib lub sij hawm, paub qhov txawv ntawm qhov ntsuas t sib raug rau txhua qhov ntsuas ntawm lub vaj huam sib luag. qhov t.
Ua tib zoo saib xyuas qhov tseeb ntawm kev siv multimeter, vim tias feem ntau ntawm kev ua tsis tiav ntawm multimeter yog tshwm sim los ntawm kev ua haujlwm tsis raug. Yog li ntawd, qhov tseeb siv ntawm multimeter yog qhov zoo tshaj plaws txij nkawm rau lub multimeter.
Tsis tas li ntawd, tsuas yog los ntawm kev siv lub multimeter kom raug tuaj yeem ntsuas qhov yuam kev raug txo kom tsawg. Lub multimeter yuav tsum tau muab tso rau kab rov tav ua ntej siv, thiab xyuas seb tus pointer yog xoom. Yog hais tias tsis yog, kho tus neeg kho tshuab xoom hloov ntsia hlau nyob rau hauv nruab nrab ntawm lub multimeter kom lub pointer taw tes rau xoom. Txuas cov hlau txuas ntawm cov pas ntsuas liab mus rau lub davhlau ya nyob twg liab lossis lub qhov (socket) cim nrog "ntxiv", thiab txuas cov hlua txuas ntawm cov pas ntsuas dub rau lub davhlau ya nyob twg dub lossis lub qhov (socket) cim nrog "ib".
Tig qhov hloov mus rau txoj haujlwm xav tau raws li qhov khoom yuav ntsuas. Piv txwv li, thaum ntsuas qhov hluav taws xob AC, qhov hloov pauv yuav tsum tau tig mus rau lub sijhawm sib xws. Ntawm qee lub hom phiaj dials, hom xaiv pob qhov rooj thiab qhov txwv kev hloov pauv pob qhov rooj raug teeb tsa nyias. Thaum siv, hom xaiv pob qhov rooj yuav tsum tau tig mus rau qhov sib thooj iav yuav tsum tau kuaj, thiab tom qab ntawd lub t txwv hloov pob qhov rooj yuav tsum tig mus rau cov iav sib thooj kom tau txais qhov tsim nyog t txwv. Kev saib xyuas tshwj xeeb yuav tsum tau them rau kev xaiv hom, txwv tsis pub muaj qhov tshwm sim loj heev.
