Nws yog ib qho yooj yim los siv ib lub multimeter los yog megohmmeter los xyuas qhov Circuit Court
Xyuas cov AC thiab DC voltage ntawm kab; Nws yog ib qho yooj yim los siv lub pointer multimeter los yog teem ib lub multimeter rau on-off ntawm kab.
Yog tias koj txheeb xyuas AC tam sim no hauv kab, nws yog qhov zoo dua los yuav lub ntsuas ntsuas digital kom yooj yim.
Siv lub megohmmeter rau lub cev muaj zog thiab cov xaim hluav taws xob uas yuav tsum tau ntsuas qhov kev tiv thaiv hluav taws xob rau kev kuaj xyuas Circuit Court;
Lawv txiav txim siab txog kev siv raws li lawv txoj haujlwm, thiab lub megohmmeter yog qhov kev xaiv zoo tshaj plaws rau kev kuaj cov khoom siv hluav taws xob rwb thaiv tsev; Nws tsis tuaj yeem hloov los ntawm multimeter; vim hais tias tus nqi ntawm cov rwb thaiv tsev tsis kam ntawm cov khoom siv hluav taws xob kuaj yog qhov loj, tag nrho hauv ob peb megohms Los yog ntau tshaj kaum ntawm megohms, qhov ntsuas ntawm lub multimeter yog qhov tsis raug hauv qhov ntau. Tsis tas li ntawd, lub zog hluav taws xob siv hluav taws xob siv los ntawm multimeter thaum ntsuas qhov tsis kam yog tsawg heev (hauv qab 9V), thiab tus nqi tiv thaiv tau nthuav tawm ntawm qhov tsis tshua muaj hluav taws xob tsis tuaj yeem cuam tshuam tus nqi tiag tiag ntawm kev tiv thaiv hluav taws xob nyob rau hauv high voltage. Yog li ntawd, txawm hais tias lub multimeter kuj tseem tuaj yeem ntsuas qhov ntsuas hluav taws xob tiv thaiv tus nqi ntawm ntau txhiab ohms, cov nqi hluav taws xob tiv thaiv ntsuas los ntawm nws tsuas yog siv tau raws li kev siv. Thaum kuaj cov rwb thaiv tsev ntawm cov khoom siv hluav taws xob, tsuas yog lub siab voltage thiab qis tam sim no megohmmeter (250 ~ 2500V) tuaj yeem siv rau kev ntsuas, es tsis txhob siv multimeter.
Multimeter yog ib qho cuab yeej siv ntau yam, ntau yam khoom siv portable. Raws li cov qauv ntsuas sib txawv thiab cov qauv qhia, nws tuaj yeem muab faib ua pointer multimeters thiab digital multimeters.
Multimeters feem ntau siv tau los ntsuas DC tam sim no, DC voltage, AC voltage, tsis kam, qib, thiab lwm yam, thiab qee qhov kuj tuaj yeem ntsuas AC tam sim no, capacitance, inductance, thiab transistor magnification, yog li nws yog qhov tseem ceeb rau hluav taws xob engineering, electromechanical thiab txij nkawm. departments. Nws yog cov cuab yeej siv dav dav thiab siv dav hauv kev ntsuas hluav taws xob.
Tus pointer multimeter, tseem hu ua analog multimeter, yog ib qho kev ntsuas ntau lub hom phiaj nrog lub ntsuas lub taub hau ua cov ntsiab lus tseem ceeb. Tus nqi ntsuas yog nyeem los ntawm tus pointer ntawm lub ntsuas lub taub hau, thiab nws tuaj yeem soj ntsuam qhov kev hloov pauv ntawm cov khoom ntsuas.
Digital multimeter yog ib qho cuab yeej uas sib xyaw ua ke hauv tshuab hluav taws xob thiab microcomputer technology. Nws siv cov kua siv lead ua kua los qhia ncaj qha rau qhov ntsuas tus nqi, uas hloov pauv lub voj voog thiab cov qauv ntawm cov khoom siv pointer multimeter. Nws muaj qhov zoo ntawm qhov me me, lub teeb yuag, qhov ntsuas dav dav, Nws muaj qhov zoo ntawm ntau yam kev ntsuas kev ua haujlwm, kev nyeem tau yooj yim, ntsuas nrawm nrawm, ntsuas qhov tseeb, siab rhiab heev, thiab muaj zog tshaj lub peev xwm.
