Puas yog nws yooj yim dua los kuaj xyuas lub voj voog nrog lub multimeter lossis megohmmeter?
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.
Txhawm rau txheeb xyuas qhov Circuit Court, siv lub megohmmeter rau cov motors, cable conductors, thiab lwm yam uas yuav tsum tau ntsuas kev tiv thaiv rwb thaiv tsev;
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 qhov kev tiv thaiv ntawm rwb thaiv tsev tsis kam ntawm cov khoom siv hluav taws xob raug kuaj yog qhov loj, nyob rau hauv ntau ntawm ntau megohms. Los yog ntau tshaj kaum tawm megohms. Qhov ntsuas ntawm 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 qis heev (hauv qab 9V), thiab tus nqi tiv thaiv tau nthuav tawm ntawm qhov tsis tshua muaj hluav taws xob tsis cuam tshuam qhov tseeb tus nqi ntawm rwb thaiv tsev nyob rau hauv high voltage. Yog li ntawd, txawm hais tias lub multimeter tuaj yeem ntsuas qhov ntsuas hluav taws xob tiv thaiv tus nqi ntawm ntau txhiab ohms, qhov ntsuas hluav taws xob tiv thaiv 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 tshuab hluav taws xob siab thiab qis tam sim no megohmmeter (250 ~ 2500V) tuaj yeem siv rau kev ntsuas, thiab multimeter siv tsis tau.
Multimeter yog ib qho khoom 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. Qee qhov tseem tuaj yeem ntsuas AC tam sim no, capacitance, inductance thiab amplification yam ntawm transistors, thiab lwm yam, yog li lawv yog qhov tseem ceeb rau hluav taws xob engineering, electromechanical thiab tu departments. Nws yog cov cuab yeej siv dav dav thiab siv dav hauv kev ntsuas hluav taws xob.
Analog multimeter, tseem hu ua analog multimeter, yog ib lub hom phiaj ntsuas ntau yam nrog ib lub 'meter' raws li cov ntsiab lus tseem ceeb. Tus nqi ntsuas yog nyeem los ntawm tus pointer ntawm lub 'meter'. Nws tuaj yeem soj ntsuam qhov kev hloov pauv tsis tu ncua ntawm tus nqi ntsuas.
Digital multimeter yog ib qho cuab yeej uas sib txuas cov tshuab hluav taws xob thiab microcomputer technology. Nws siv lub vijtsam LCD los qhia ncaj qha ntsuas qhov tseem ceeb, uas hloov pauv lub voj voog thiab cov qauv ntawm cov tshuaj analog multimeter. Nws muaj qhov me me, lub teeb yuag, qhov ntsuas dav dav, Nws muaj qhov zoo ntawm ntau yam kev ntsuas kev ua haujlwm, kev nyeem ntawv yooj yim, ntsuas nrawm nrawm, ntsuas qhov tseeb, siab rhiab heev, thiab muaj peev xwm ua haujlwm dhau.
