Xaiv Txoj Kev ntawm Digital Multimeter
Muaj ntau pua hom rau digital multimeter. Xaiv qhov tsim nyog digital multimeter yog mob taub hau. Qhov teeb meem yog yuav ua li cas thiaj nrhiav tau lub tshuab digital multimeter uas tsim nyog tus nqi thiab ua tau raws li qhov yuav tsum tau ua.
Ua ntej txiav txim siab, nws yuav tsum tau txiav txim siab seb yuav tsum ntsuas qhov tseem ceeb? Koj puas ua haujlwm ntsuas qhov tseeb? Puas yog nws siv tus lej 7 lossis 8th tiag tiag rau kev ntsuas? Yog tias muaj, koj yuav tsum xaiv lub siab-precision countertop digital multimeter vim nws muaj kev ruaj ntseg zoo. Yog tias koj xav siv nws hauv qhov kev hloov kho, koj tuaj yeem xaiv 61/2f ntsis digital multimeter uas tau sib xws nrog PXI thiab VXI. Feem ntau hais lus, muaj ntau cov digital multimeters nrog cov neeg siab thiab daws teeb meem, tab sis qhov kev ntsuas qhov xav tau tsis tas yuav muaj qhov raug siab thiab daws teeb meem. Txawm hais tias kev daws teeb meem yog qhov ua tau zoo hauv kev tsim qauv, kev ua tiav cov kev ntsuas siab siab kawg yog nyob ntawm qhov zoo ntawm cov cuab yeej ntsuas. Piv txwv li, thaum siv tus lej 81/2 tus lej rau kev ntsuas, ib tus yuav tsum tau ceev faj thiab paub txog, txwv tsis pub tsuas yog muaj lub tshuab ntsuas ntau yuav tsis tas yuav ua tau zoo. Ntawm qhov tod tes, ntau qhov qis-kawg digital multimeters kuj yog qhov kev xaiv tsim nyog. Yog tias tsuas yog qhov ntsuas qhov tseeb ntawm 5% yog qhov yuav tsum tau ua thiab tsis muaj ntau qhov kev ntsuas, ces xaiv qhov qis kawg digital multimeter. Qhov yooj yim kom muaj nuj nqis uas tuaj yeem ntsuas los ntawm digital multimeter yog AC thiab DC voltage, tam sim no, thiab tsis kam. Qee tus neeg qhov kev ntsuas xav tau poob ntawm ob qhov xwm txheej hnyav uas tau hais los saum toj no. Nws yog ib qho nyuaj rau kev txiav txim siab ntawm hom digital multimeter xaiv. Vim tias lawv xav tau kev ntsuas qhov tseeb thiab kev daws teeb meem, nrog rau cov nqi pheej yig. Txhawm rau xaiv qhov zoo tshaj plaws, nws raug nquahu kom lawv ua tib zoo nyeem phau ntawv qhia thiab cov ntaub ntawv hauv qab no. Muaj ntau yam high-precision tabletop digital multimeters thiab low-end handheld digital multimeters muaj rau kev nyeem cov ntawv me me. Txawm li cas los xij, cov cim qhia ntawm ntau yam digital multimeters tsis sib xws hauv lawv cov kab lus. Piv txwv li, qhov tseeb ntawm DC voltage yog qee zaum qhia tias yog% ntawm kev nyeem ntawv ntxiv% ntawm qhov ntau. Qee qhov qhia tau tias yog% ntawm kev nyeem ntawv ntxiv rau ob peb suav, thaum lwm tus tau qhia tias yog% ntawm kev nyeem ntawv ntxiv rau ob peb volts. Rau ib hom digital multimeter, yog tias koj paub tias pes tsawg tus suav suav nrog nws tus nqi saturation, koj tuaj yeem hloov ib qho kev qhia mus rau lwm qhov. Cov lus saum toj no feem ntau pom.
