Dab tsi yog qhov txiaj ntsig zoo tshaj plaws multimeter rau tus kws tshaj lij?
Multimeters siv hauv tsev tsis tshua siv. Tsuas yog yuav ib qho analog multimeter, uas raug nqi li ob peb lub kaum os yuan. Nws kuj tseem haum rau cov pib tshiab, thiab koj yuav tsis hnov mob yog tias nws puas lawm. Qhov kom zoo dua ntawm analog multimeter yog tias nws pheej yig, tab sis qhov tsis zoo yog tias nws tsis yog intuitive los nyeem cov ntaub ntawv thiab tuaj yeem yooj yim puas yog tias nws tsis ua haujlwm zoo.
Feem ntau siv portable multimeters tuaj yeem muab faib ua peb hom: mechanical pointer multimeters, digital display multimeters, thiab clamp-on digital multimeters.
Tshawb xyuas qhov zoo, qhov tsis zoo thiab tus nqi ntawm peb lub moos no.
Mechanical pointer multimeter
Hom 'meter' no tsis tshua muaj kev cuam tshuam los ntawm qhov kub thiab txias, av noo, thiab sib nqus teb, thiab nws qhov ntsuas qhov tseem ceeb yog qhov ruaj khov thiab nkag siab. Tsis zoo li cov ntsuas ntsuas digital, uas qee zaum hloov pauv thiab dhia ncig, cov qub tub rog hluav taws xob thiab cov neeg saib xyuas hluav taws xob feem ntau nyiam nws. Txawm li cas los xij, lub iav yuav tsum tau kho kom raug thaum ntsuas. Thaum ib tug phooj ywg ntawm kuv ntsuas 380V voltage, nws tsis nco qab kho lub iav. Lub sijhawm ntawd, muaj lub suab "bang" thiab lub 'meter' hlawv. Hmoov zoo, nws zoo, tab sis nws kuj ntshai heev. Tus nqi yog pheej yig, xws li ib lub kaum os mus rau kaum ob yuan.
Digital Multimeter
Cov khoom siv hluav taws xob Precision feem ntau cuam tshuam los ntawm cov chaw sib nqus, cov av noo thiab lwm qhov chaw, tab sis yog tias lawv tsis siv rau kev ntsuas ntsuas hluav taws xob hauv Circuit Court, qhov cuam tshuam yog qhov tseem ceeb lossis tsis txaus ntseeg. Cov txiaj ntsig kev ntsuas tau pom meej meej, thiab tshwj xeeb tshaj yog haum rau kev siv hauv tsev thiab kev ntsuas hluav taws xob tam sim no muaj zog. Hom 'meter' no yog qhov siv dav tshaj plaws tam sim no. Tus nqi tsis siab, feem ntau tsawg dua 100 yuan.
Clamp hom digital zaub multimeter
Feem ntau hu ua clamp meter, nws txoj haujlwm zoo ib yam li cov ntsuas ntsuas digital, tab sis nws muaj kev ua haujlwm ntxiv. Koj tuaj yeem ntsuas cov kab tam sim no ntawm txoj kab los ntawm kev tso lub 'meter' clamp rau ntawm cov hlau nyob tsis tas yuav tsum poke cov hlau nyob nruab nrab nrog ob koob. Nws muaj kev nyab xeeb dua. Siab dua me ntsis. Piv txwv li, cov phooj ywg ntawm Wukong feem ntau nug cov lus nug txog vim li cas vim li cas lub Circuit Court breaker hauv nws lub tsev thiaj li tsis mus. Yog tias koj kuaj nws nrog lub ntsuas ntsuas clamp, koj yuav paub tias qhov tam sim no siab npaum li cas. Tom qab ntawd koj yuav paub seb nws puas yog vim cov xaim nyias nyias lossis lub Circuit Court breaker me dhau. Kuv yuav ib tug rau 95 yuan nyob ib ncig ntawm 2010. Thaum lub sij hawm ntawd, nws yog yeej ob hnub nyiaj hli. Nws twb yuav luag kaum xyoo lawm. Sib nrug los ntawm kev hloov ob txhais tes, kuv tseem siv nws, uas zoo nkauj heev. Tus nqi ntawm cov khoom lag luam zoo tib yam tsuas yog nyob ib ncig ntawm 100 txog 200, thiab tus nqi tau txais.
Cov ntsiab lus
Tus kheej, kuv xav tias rau kev siv hauv tsev, ib qho zoo tib yam digital zaub meter yog txaus, thiab rau kev lag luam siv, lub ntsuas ntsuas clamp yog qhov ua tau zoo dua.
