Kuv xav yuav ib lub multimeter uas yog qhov tseeb dua.
Rau cov phooj ywg ntawm electricians, multimeter yooj yim thiab tswv yim tseem ceeb. Ntau tus phooj ywg hauv kev xaiv ntawm multimeters xav tias qhov tseeb yog qhov tseem ceeb dua, thiab txawm tias yuav tsum tau multimeters yog ob peb txhiab ntawm qhov tseeb. Qhov tseeb, kuv xav tias rau kev ua haujlwm txij nkawm zoo tib yam, qhov tseeb yog qhov tsis tseem ceeb raws li koj xav, ntawm chav kawm, tshwj tsis yog kev saib xyuas ntawm qee qhov kev txiav txim siab Circuit Court boards.
Piv txwv li, ntsuas qhov hluav taws xob ntawm lub cev muaj zog, qhov hluav taws xob yog 380V thiab 383V rau qhov kev txiav txim ntawm txoj kab txhaum tsis muaj qhov cuam tshuam. Multimeter tsis yog ib qho kev siv thev naus laus zis, ntau hom multimeter yuam kev tsis txawv ntau. Kuv xav tias piv rau qhov tseeb, nws tseem ceeb dua kom ua tau zoo, ruaj khov, tsis yooj yim tawg, thiab tsis poob ntawm cov saw ntawm lub sijhawm tseem ceeb.
Pointer thiab Digital Meter
Muaj ob hom multimeters: pointer meters thiab digital meters.
Pointer multimeter input impedance yog qhov tsawg, tsis muaj qhov tseeb, tab sis nws muaj zog tiv thaiv kev cuam tshuam, tuaj yeem pom qhov cuam tshuam qhov loj ntawm qhov kev hloov.
Digital multimeter input impedance yog siab, siab precision, intuitive nyeem, feature-nplua nuj, xws li ntsuas voltage, tam sim no, kub, capacitance thiab dab tsi yuav ua tau. Vim tias cov ntsuas ntsuas digital siv cov qauv ntsuas tam sim, yog li nws yooj yim los tshwm sim qhov tshwm sim digital dhia.
Yog hais tias koj yog ib tug novice pib, kuv xav kom pib nrog tus pointer multimeter. Txawm hais tias qhov pib ntawm kev sib cuag nrog tus pointer multimeter yuav hnov qhov teeb meem nyeem ntawv, tab sis siv rau nws, koj yuav hlub nws. Ntau qhov kev ntsuam xyuas Circuit Court, qhov tseeb, tsis tas yuav tsum tau nyeem, tsuas yog xav pom tus taw tes rau sab ntawm deflection tuaj yeem ua tau. Yog tias nws yog lub ntsuas hluav taws xob digital, koj kuj yuav tsum tau sib piv cov txiaj ntsig ua ntej thiab tom qab ntsuas kom paub qhov Circuit Court.
MF50 thiab MF47 yog ob qho tib si classic qauv ntawm pointer multimeter, thiab MF47 qauv feem ntau yog siv rau kev taw qhia thiab kev qhia ntawm cov hluav taws xob. Raws li rau lub pointer multimeter hom, "Nanjing Jinchuan Electric Meter Factory (yav tas los Nanjing Electric Meter Factory)" yog ib hom qub, txawm hais tias tus qauv tshiab tsis yog li ntawd, tuav hauv tes lub teeb, tab sis qhov zoo ntawm tus pointer multimeter kuj yog. zoo heev, nws tsim nyog muaj.
