Yuav ua li cas yog vim li cas rau kev ntsuas peb-theem kuj tshuav nyiaj li cas nrog ib tug multimeter
Lub twj tso kua mis peb-theem siv lub megohmmeter los ntsuas qee qhov xau. Yuav kom meej meej, nws yuav tsum tau shaken nrog megohmmeter thaum lub sij hawm hluav taws xob, uas txhais tau hais tias lub rwb thaiv tsev tsis zoo. Nws txhais tau hais tias qee qhov ntawm cov cable lossis lub cev muaj zog tsis zoo los ntawm lub plhaub. Tab sis tsis muaj dab tsi tsis ncaj ncees lawm nrog lub coils ntawm lub cev muaj zog nws tus kheej. Yog li koj siv multimeter los ntsuas peb-theem kuj yog qhov zoo. Qhov no tsis yog qhov tsis sib xws. Nrhiav thiab daws cov rwb thaiv tsev tsis zoo. Qhov ntawd yog nws.
Kuv tsuas yog tham txog txoj kev tuav hauv kev ua haujlwm tiag tiag. Feem ntau, ib qho {{0}} volt meter yog siv los ntsuas qhov rwb thaiv tsev ntawm cov kauj thiab lub plhaub. Muaj peb qhov tshwm sim. Ib qho yog tias qhov tsis kam yog xoom. Raws li cov lus hais mus, yog lub plhaub yog kov, nws yog av. Yog, lub cev muaj zog tawg. Qhov thib ob yog qhov kev tiv thaiv tsis kawg, qhia tias lub cev muaj zog zoo. Qhov thib peb yog tias muaj kev tiv thaiv, uas txhais tau hais tias muaj teeb meem nrog lub rwb thaiv tsev. Raws li kuv qhov kev paub dhau los, cov rwb thaiv tsev tiv thaiv ntau dua 0.5 megohm. , kuj tseem siv tau, yog tias nws qis dua 0.5 megohm, nws siv tsis tau. Qhov teeb meem thib ob yog tias nws tsis tuaj yeem siv multimeter los ntsuas qhov sib npaug ntawm peb-theem kuj tseem ceeb. Yog vim li cas yog tias qhov sib cuam tshuam luv luv ntawm lub cev muaj zog coil tsis tuaj yeem kuaj pom. Hauv kuv qhov kev paub, txawm tias lub cev muaj zog zoo muaj qhov sib txawv ntawm qhov sib txawv. Yog, muaj qee lub tshuab hluav taws xob siab nrog cov coils tuab. Qhov kev tiv thaiv koj ntsuas yog xoom ohms. Kuv paub tias nws tsis zoo li qub.
Yog tias koj siv lub megohmmeter los ntsuas qhov kev tawm tsam ntawm peb-theem coils thaum lub peb-theem coils tsis raug txiav, nws txhais tau tias koj tsis nkag siab qhov kev nkag siab zoo ntawm qhov ntsuas txhua, yog li tsis txhob ua si, yog tias koj tsis nkag siab qhov kev nkag siab zoo ntawm cov twj paj nruag, yog li tsis txhob ua si, megohmmeter yog ntsuas peb-theem coils Qhov kev tiv thaiv ntawm lub plhaub thiab lub plhaub, lub multimeter ntsuas qhov kev tiv thaiv ntawm cov coils, yog tias koj ntsuas qhov xwm txheej, nws txhais tau hais tias cov cua kub ntawm lub twj tso kua mis dej ua rau lub rwb thaiv tsev rau hnub nyoog, thiab coil winding yuav tsum tau hloov! Kuv xav tias koj yuav tsum nyob rau hauv rooj plaub tom kawg.
