Yuav ua li cas yog vim li cas rau qhov sib npaug ntawm peb-theem kuj ntsuas nrog ib tug multimeter
Peb-theem dej twj tso kua mis nrog megohmmeter ntsuas ntawm qee qhov to, raws nraim yuav tsum yog cov ntaub ntawv ntawm lub zog hluav taws xob, nrog megohmmeter co, uas yog hais tias, tsis zoo rwb thaiv tsev. Nws txhais tau hais tias lub cable lossis lub cev muaj zog, qee qhov ntawm cov rwb thaiv tsev tsis zoo nrog lub plhaub. Tab sis tsis muaj dab tsi tsis ncaj ncees lawm nrog lub kauj ntawm lub cev muaj zog nws tus kheej. Yog li koj ntsuas peb-theem tsis kam nrog lub multimeter yog qhov zoo. Qhov no tsis yog qhov tsis sib xws. Nrhiav qhov chaw nrog rwb thaiv tsev tsis zoo thiab nrog nws. Nws yuav zoo.
Kuv tsuas yog hais tias nyob rau hauv qhov tseeb ua hauj lwm ntawm txoj kev ua, feem ntau, nrog ib tug {{0}}}volt co lub rooj los ntsuas cov rwb thaiv tsev tsis kam ntawm lub kauj thiab lub plhaub, muaj peb yam kev tshwm sim, ib tug hom kev tiv thaiv yog xoom, peb hais nyob rau hauv ib qho kev sib piv uas kov lub plhaub kuj yog hauv av, lub cev muaj zog yog qhov tsis zoo, qhov thib ob ntawm kev tiv thaiv tsis muaj qhov kawg, qhia tias lub cev muaj zog yog qhov zoo, thiab qhov thib peb ntawm qhov xwm txheej yog tias muaj tsis kam, uas qhia tau hais tias muaj teeb meem ntawm cov rwb thaiv tsev, raws li kuv qhov kev paub, cov rwb thaiv tsev tiv thaiv ntau dua 0.5 megohm rooj plaub, tseem siv tau, tsawg dua 0.5 megohm tsis tuaj yeem siv. Qhov thib ob qhov teeb meem yog siv ib tug multimeter los ntsuas qhov peb-theem kuj tshuav nyiaj li cas, yog tsis tau, yog vim li cas yog vim li cas lub cev muaj zog coil hloov luv luv Circuit Court tsis ntsuas, nyob rau hauv kuv kev, ob qho tib si yog ib tug zoo lub cev muaj zog, tus nqi kuj yog tsis. Raws nraim tib yam, muaj qee lub zog lub cev muaj zog, coil yog tuab heev, koj ntsuas qhov ntsuas tus nqi yog xoom ohms, uas yog qhov tsis tuaj yeem piav qhia qhov teeb meem, saib ntawm peb theem sib npaug tsuas yog lub cev muaj zog pib thiab ua haujlwm, thiab nqa daim npav daim npav daim npav peb-theem tam sim no, koj yuav paub qhov qub lossis tsis yog. Paub li qub los tsis yog.
Yog hais tias koj tsis disconnect peb-theem kauj nrog megohmmeter los ntsuas qhov tsis kam ntawm peb-theem kauj, qhia tias koj tsis nkag siab qhov kev nkag siab zoo ntawm cov twj paj nruag, lossis tsis ua si, yog tias lub megohmmeter ntsuas qhov tsis kam ntawm peb-theem kauj thiab lub plhaub, lub multimeter los ntsuas qhov tsis kam ntawm cov coils, xws li koj ntsuas cov ntaub ntawv ntawm lub twj tso kua mis kub los ntawm cov rwb thaiv tsev deterioration, yuav tsum tau hloov lub coil windings! Kuv xav tias koj yuav nyob hauv qhov xwm txheej kawg.
