Yuav ua li cas xaiv ib tug multimeter rau tsev siv, cia saib ob peb yam lus
Hais txog kev yuav khoom ntawm tsev neeg multimeters, multimeters siv nyob rau hauv cov tsev neeg feem ntau yog siv los ntsuas thiab kho cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam. Yuav ua li cas yuav lawv thiab cov teeb meem dab tsi yuav tsum tau them rau.
1. Cov kev cai yooj yim
Lub tsev multimeters xav tau qhov tseeb tsim nyog, ruaj khov, kev cia siab, kev lag luam thiab kav ntev, nqa tau yooj yim, thiab tus nqi pheej yig.
2. Ntau hom
Pocket multimeters xws li MF40, MF41, MF30, thiab MF72 tuaj yeem siv los ntsuas cov peev txheej, inductance, thiab qhov loj ntawm cov transistors.
MF30 yog multimeter nrog siab rhiab heev, thiab MF72 yog haum rau kho TV teeb thiab xov tooj cua recorders.
Qhov siab-rhiab heev multimeter feem ntau muaj 500 hom, qhov tsis zoo yog tias nws loj thiab hnyav, thiab qhov tsis zoo yog tias nws muaj qhov siab.
Qhov rhiab heev ntawm MF15 thiab MF16 kuj yog qhov siab, thiab qhov ntim me me, thiab hom multimeter no feem ntau yuav hauv tsev neeg.
3. Digital multimeter
Lub multimeter digital yog tus cwj pwm los ntawm kev nkag siab zoo heev, ua tiav cov haujlwm, cov khoom siv nkag siab, kev ntseeg tau zoo, kev siv hluav taws xob tsawg, me me thiab lub teeb yuag. Hom kev siv feem ntau yog DT-830, thiab lwm yam. Nws qhov hloov pauv tuaj yeem ua tiav qhov kev xaiv ntawm kev sim ua haujlwm thiab ntau yam tib lub sijhawm.
4. Cov ntsiab lus ntawm kev yuav khoom
Thaum muas lub multimeter, ua ntej saib rooj plaub, txawm tias nws yog du thiab ci, tsis muaj khawb los yog tawg, thiab lub nplai ntawm lub dial yog ntshiab thiab huv si tsis muaj stains.
Tom qab ntawd, tig qhov hloov pauv kom pom tias nws yog lub teeb thiab yoog raws, tsis muaj teeb meem thiab suab nrov. Koj tuaj yeem co lub multimeter horizontally ob peb zaug, tus pointer yuav tsum muaj damping zoo, lub viav vias yuav tsum tsis txhob loj dhau, thiab tsis muaj suab nrov hauv lub ntsuas.
Txheeb xyuas qhov kev hloov kho xoom xoom (lub corrector nyob nruab nrab ntawm qhov chaw) kom pom tias tus pointer tuaj yeem hla xoom thiab tuaj yeem raug kho kom raug rau xoom point.
Thaum kawg, xyuas lub ohm iav ntawm lub roj teeb ntawm lub moos: luv luv-circuit ob lub xeem coj, tig lub xoom-hloov potentiometer rau pem hauv ntej thiab thim rov qab, tus pointer yuav tsum viav vias rov qab los ntawm "0" Ω, thiab tuaj yeem raug kho kom raug rau xoom.
Tsis tas li ntawd, koj tuaj yeem tshawb xyuas raws li cov khoom lag luam ua tau zoo hauv phau ntawv qhia seb nws ua tau raws li cov kev cai tshwj xeeb.
