Thaum muas ib lub multimeter, koj yuav tsum ua qhov tseem ceeb hauv qab no yam tseem ceeb
Multimeters yog qhov tseem ceeb heev hauv kev ua haujlwm niaj hnub ntawm cov neeg ua haujlwm kho hluav taws xob. Muaj ntau ntau hom multimeters ntawm lub khw, thiab cov nqi sib txawv heev. Feem ntau, thaum peb xaiv, peb tsis meej pem, txhawj xeeb tias tus nqi yuav pheej yig thiab qhov zoo yuav tsis zoo, thiab txhawj xeeb tias cov khoom xaiv yuav tsis haum. Yog li, peb tuaj yeem xaiv lub multimeter peb xav tau li cas? Ntxiv nrog rau kev txiav txim siab txog kev ua tau zoo ntawm cov khoom lag luam, hom, nqe, thiab tom qab- kev muag khoom los ntawm cov tuam txhab thiab cov neeg muag khoom, kuv xav qhia cov hauv qab no:
(1) Cov txheej txheem tso saib.
Digital multimeters yog tsim rau cov xwm txheej uas yuav tsum tau ntsuas siab; Analog multimeters yog haum rau ntsuas qhov xwm txheej nrog cov kev cai dav dav; Tam sim no muaj dual zaub multimeter uas sib txuas ua haujlwm analog thiab digital, haum rau kev sim cov xwm txheej nrog cov ntsiab lus nplua nuj. Nrog rau kev txhim kho ntawm kev ntsuas kev ua haujlwm thiab tus nqi -kev ua tau zoo ntawm digital multimeters, kev siv pointer multimeters yuav dhau los ua tsawg.
(2) Kev ntsuas yooj yim.
Kev ntsuas qhov yooj yim yog qhov tsim nyog rau cov khoom siv dav dav, xws li DC tam sim no, qhov hluav taws xob ntau, AC qhov hluav taws xob ntau, thiab ntau yam tsis kam.
Thaum tsim nyog, kev txiav txim siab yuav tsum tau muab rau seb puas xav tau AC tam sim no kev ua haujlwm.
(3) Ntau yam ntxiv.
Raws li kev xav txog kev ntsuas ntxiv tuaj yeem ua rau muaj ntau yam yooj yim rau kev saib xyuas txhua hnub, xws li hom capacitor (qee lub digital multimeters muaj peev xwm txog li 2000 μ F), transistor static coefficient ntsuas hom, Circuit Court breaker test hom, diode (DT) ntsuas hom, thiab lwm yam.
(4) Kev ntsuas qhov tseeb.
Yog hais tias qhov ntsuas yog ib qho yuav tsum tau ua, qhov ntsuas qib yuav raug xaiv kom qis dua; Yog tias cov cuab yeej siv los kho cov hluav taws xob hluav taws xob thiab xav tau kev ua haujlwm zoo dua, qhov ntsuas qib yuav tsum siab dua me ntsis; Yog tias qhov ntsuas tau siv rau kev tshawb fawb txog kev tshawb fawb, yuav tsum xaiv qhov ntsuas qib siab dua.
Thaum muas ib lub multimeter, yog tias tus nqi tsis raug txiav txim siab, qhov tseem ceeb yuav tsum tau ua raws li cov lus qhia tshwj xeeb, thaum tseem xav txog qhov pom thiab qhov loj me.
Yog tias siv hauv chav kuaj, cov khoom uas muaj qhov ntim loj dua, qhov tseeb dua, thiab qhov ntsuas qhov dav tuaj yeem yuav.
Yog tias nws nquag siv sab nraud thiab muaj kev ua haujlwm zoo, yuav ib nrab -ntau yam nrog rau qhov zoo nkauj dua.
Yog tias nws yog siv rau kev tsim kho sab nraum zoov, yuav ib lub multimeter portable uas yog me me, pheej yig tus nqi, tuaj yeem ua tau raws li kev ntsuas dav dav, tsis muaj dej, pov thawj mildew, thiab muaj cov ntaub thaiv npog.
Rau cov kws tshawb fawb, ib qho oscilloscope multimeter nrog ob qho tib si digital zaub thiab oscilloscope zog tuaj yeem siv tau.
Qhov tseeb, kev xaiv ntawm multimeter tsis yog qhov nyuaj. Nws raug txiav txim ib los ntawm ib qho raws li cov xwm txheej ntawm cov khoom ntsuas thiab kev siv ib puag ncig. Kuv vam tias tom qab nyeem tsab xov xwm no, koj yuav tsis to taub li cas thaum xaiv ib tug multimeter.
