Kuv tsis paub seb nws puas yog AC lossis DC voltage, yuav ua li cas ntsuas nws nrog tus kws hluav taws xob multimeter
Yog hais tias AC / DC voltage ntau ntawm lub multimeter thiab AC / DC hom ntsuas qhov ntsuas qhov tseeb yog qhov tseeb, cov multimeter digital yuav tso saib - kos npe thaum ntsuas DC voltage, thiab tus pointer ntawm pointer multimeter yuav viav vias hauv qhov zoo.
DC voltage nyeem ntawv ntawm digital multimeter yuav tsawg heev los yog pes tsawg thaum ntsuas AC voltage, thiab DC voltage nyeem ntawv ntawm tus pointer multimeter kuj yuav me me los yog tsis muaj viav vias thaum ntsuas AC voltage. Tib yam muaj tseeb rau kev ntsuas DC voltage nrog cov ntaub ntawv AC voltage ntawm multimeter. Lub sijhawm no, koj yuav tsum pom tias hom hluav taws xob ntsuas tsis raug, thiab koj yuav tsum rov xaiv qhov tseeb AC / DC voltage hom iav ntawm multimeter.
Tsis tas li ntawd, thaum lub ntsuas hluav taws xob ntawm lub zog hluav taws xob yuav tsum tau kuaj tsis meej, lub iav high-voltage yuav tsum tau hloov mus rau qhov qis-voltage iav ua ntej, thiab tom qab ntawd cov iav qis-voltage yuav tsum maj mam hloov mus rau lub iav nrog cov iav. zoo tshaj plaws kev daws teeb meem nyeem ntawv thiab qhov tseeb tshaj plaws ntawm qhov ntsuas qhov ntsuas kom muaj kev nyab xeeb.
Koj tuaj yeem ntsuas nws thawj zaug nrog AC voltage ntawm 750V, thiab saib tus nqi tso tawm. Yog tias nws me me los yog qhov pib tsis tshwm sim, koj tuaj yeem sim nws nrog cov ntaub ntawv DC voltage!
Ua ntej siv qhov siab tshaj plaws AC voltage rau kev ntsuas, thiab tom qab ntawd siv qhov tsim nyog rau kev ntsuas qhov tseeb tom qab txiav txim siab qhov ntau. Yog tias tsis muaj tus nqi ruaj khov hauv qhov tseeb, nws yog DC. Hloov mus rau qib siab tshaj ntawm DC voltage los ntsuas tus nqi kwv yees. Tom qab txiav txim siab qhov ntau, hloov mus rau qhov tsim nyog rau kev nyeem kom raug.
Siv cov ntaub ntawv AC voltage siab tshaj plaws los ntsuas qhov zoo thiab qhov tsis zoo ua ntej. Yog tias ob qhov hluav taws xob zoo sib xws, nws yog AC, txwv tsis pub nws yog DC ~
Hloov tam sim no tsis muaj qhov zoo thiab tsis zoo; direct tam sim no muaj qhov zoo thiab tsis zoo ncej.
Qhov no yog ib qho kev nkag siab zoo siv lub multimeter kom raug. Thaum ntsuas qhov hluav taws xob ntawm qhov hluav taws xob tsis paub, tig lub multimeter mus rau qhov siab tshaj plaws AC voltage theem, thiab tom qab ntawd kho cov iav kom haum rau cov iav uas tsim nyog raws li qhov kev ntsuas ntxhib kom ntsuas qhov tseeb.
Nws yog ib qho yooj yim heev, siv lub tshuab multimeter, pib los ntawm lub siab tshaj plaws iav los ntsuas, siv AC iav thiab DC iav los ntsuas, thiab yog tias lub iav AC ntsuas tsis tau, DC iav tuaj yeem ntsuas nws yog tam sim no ncaj qha, thiab lwm yam. . Qhov tseeb, AC lossis DC tuaj yeem txiav txim siab los ntawm cov khoom siv pins.
