Kev sib piv ntawm clamp ammeter thiab multimeter
Clamp ammeters thiab multimeters yog ob qho tib si tsim nyog "cov khoom siv" rau cov kws tshaj lij hluav taws xob. Ob lub twj paj nruag sib txawv hauv kev ua kom pom tseeb ntawm lawv txoj haujlwm. Clamp ammeters tsom rau kev ntsuas cov kab loj tam sim no, thaum multimeters tsom rau kev ntsuas qhov tsis tshua muaj hluav taws xob thiab me me tam sim no. Thaum kho circuits, qee zaum yuav tsum siv ob qho tib si ua ke. Piv txwv li, thaum kho cov khoom siv hluav taws xob uas sib txuas cov hluav taws xob muaj zog xws li cua txias, tub yees, thiab cov cuab yeej tswj hluav taws xob, ob qho tib si qee zaum siv sib npaug.
Lub ntsiab "kev tshwj xeeb" ntawm clamp ammeters
Peb paub lub ntsiab "tshwj xeeb" ntawm lub clamp ammeter los ntawm nws cov npe. Peb qee zaum hu nws lub ntsuas ntsuas tam sim no. Nws yog ib qho khoom siv hluav taws xob uas ntsuas cov dej ntws loj. Nws tuaj yeem ntsuas AC tam sim no txog li 1, 000 amps, thiab tsuas yog ntsuas 1 amp ntawm qhov tsawg kawg nkaus. Txawm tias nws qis npaum li cas, nws tsis tuaj yeem ntsuas qhov tseeb. Yog li ntawd, nws qhov tseeb tsuas yog nyob nruab nrab ntawm qib 2.5 thiab qib 5. Muaj ntau yam uas yuav tsum tau them sai sai rau thaum ntsuas cov dej ntws loj, uas cov pib tshiab yuav tsum nco ntsoov.
Lub ntsiab "kev tshwj xeeb" ntawm multimeters
Multimeter kuj tseem hu ua "universal meter". Nws lub ntsiab feature yog nws lub peev xwm ua tau zoo, uas zoo li "nws muaj peev xwm them taus rau 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, Resistance, inductance, capacitance, suab theem, diode, transistor amplification, transistor hom, thiab lwm yam. Tsis tas li ntawd, nws qhov ntsuas qhov tseeb yog ntau dua li ntawm ib lub clamp. ammeter, nrog qhov tseeb txog li 0.1, tshwj xeeb tshaj yog digital multimeter. Rau cov tam sim no loj, cov nqi tam sim no tuaj yeem ntsuas txog 10A, uas yog txaus rau cov khoom siv dav dav. cuaj zaus ntawm kaum thaum kuv tab tom ua haujlwm lossis cov khoom siv debugging kuv yuav tsum siv multimeter los ua kom tiav cov haujlwm. Yog li ntawd, nyob rau hauv cov nqe lus ntawm kev siv ntau zaus, kev siv tus nqi ntawm multimeters yog ntau dua li kev siv tus nqi ntawm clamp ammeters, yog li kuv xav tias multimeters muaj txiaj ntsig zoo dua thaum kho cov khoom siv hluav taws xob.
