Puas yog clamp ammeter hloov multimeter?
Ob lub clamp ammeters thiab multimeters yog cov cuab yeej tseem ceeb rau cov kws tshaj lij thiab cov kws tshaj lij. Muaj qhov sib txawv ntawm qhov tseem ceeb ntawm lawv txoj haujlwm. Clamp ammeters tsom rau kev ntsuas siab tam sim no circuits, thaum multimeters tsom rau ntsuas qhov tsis tshua muaj hluav taws xob thiab tsis tshua muaj tam sim no. Qee zaum, thaum kho cov khoom siv hluav taws xob, kev sib xyaw ua ke ntawm ob yog xav tau, xws li hauv kev kho cov khoom siv hluav taws xob xws li cua txias, tub yees, thiab cov khoom siv hluav taws xob tswj cov khoom siv hluav taws xob sib xyaw ua ke. Ob qho ntawm cov cuab yeej no qee zaum siv tsis muaj qhov sib txawv.
Lub ntsiab "zoo" ntawm clamp ammeters
Peb tuaj yeem qhia nws lub ntsiab "lub zog" los ntawm nws lub npe, thiab qee zaum peb kuj xa mus rau nws raws li qhov ntsuas tam sim no. Nws yog ib qho khoom siv hluav taws xob siv los ntsuas qhov tam sim no loj, nrog qhov ntsuas qhov siab tshaj plaws ntawm 1000 amperes rau kev hloov tam sim no thiab qhov ntsuas qhov tsawg kawg nkaus tsuas yog 1 ampere. Txawm tias nws qis npaum li cas, nws tsis tuaj yeem ntsuas qhov tseeb. Yog li nws qhov tseeb tsuas yog nyob nruab nrab ntawm 2.5 thiab 5 qib, thiab muaj ntau yam uas yuav tsum tau them sai sai rau thaum ntsuas cov dej ntws loj, uas cov pib tshiab yuav tsum nco.
Lub ntsiab "lub zog" ntawm ib tug multimeter
Multimeter, feem ntau hu ua "universal meter", muaj lub ntsiab kom zoo dua ntawm kev muaj peev xwm ua tau zoo, xws li muaj peev xwm tuav tau thiab tuav txhua yam kev sib ntaus sib tua. Nws tuaj yeem tsis tsuas ntsuas AC tam sim no tab sis kuj AC voltage, DC tam sim no thiab voltage, tsis kam, inductance, capacitance, suab theem, diode, transistor amplification yam, transistor hom, thiab lwm yam. Tsis tas li ntawd, nws qhov ntsuas qhov tseeb yog ntau dua li ntawm lub clamp. ammeter, thiab nws qhov tseeb tuaj yeem ncav cuag 0.1, tshwj xeeb tshaj yog rau digital multimeters. Rau cov hluav taws xob siab, tus nqi tam sim no txog li 10A tuaj yeem ntsuas tau, uas yog txaus rau cov khoom siv dav dav. Kuv yuav tsum siv lub tshuab multimeter cuaj tawm ntawm kaum zaug kom ua tiav cov haujlwm thaum kho thiab kho cov khoom siv debugging. Yog li, nyob rau hauv cov nqe lus ntawm kev siv zaus, kev siv tus nqi ntawm ib tug multimeter yog ntau dua li ntawm ib tug clamp ammeter, yog li kuv ntseeg hais tias ib tug multimeter yog zoo dua nyob rau hauv kho cov khoom siv hluav taws xob.
Multimeter nrog clamp ammeter
Nrog rau kev txhawb nqa ntawm digitalization thiab kev tsim cov khoom tshiab, ntau thiab ntau cov cuab yeej tau txais kev siv digitalization thiab dhau los ua ib qho kev nthuav dav. Analog cov cuab yeej tau maj mam raug txiav tawm ntawm kev siv. Niaj hnub no, digital clamp ammeters kuj tau tshwm sim, thiab lawv cov haujlwm tsis yog ib qho kev ntsuas nkaus xwb. Raws li kev ntsuas qhov tseeb ntawm digital clamp ammeters txhim kho, lawv lub cev muaj nuj nqis kuj tseem muaj txiaj ntsig, xws li ntsuas tam sim no, voltage, tsis kam, lub zog nquag, zaus, lub kaum sab xis, lub zog, thiab lwm yam khoom siv lub cev. Nws muaj ob txoj haujlwm ntawm multimeter thiab clamp ammeter. Kuv xav tias cov cuab yeej zoo li no yuav tau txais txiaj ntsig los ntawm ntau tus kws tshaj lij hluav taws xob yav tom ntej.
