Ua kom cov multimeters ua si lub luag haujlwm ntau dua hauv kev saib xyuas
(1) Cov hau kev rau kev sim to
Thaum ua kev ntsuas xau, pultimeter ntau. Cov qauv tshwj xeeb yog raws li hauv qab no: Kaw txhua cov khoom siv hluav taws xob hauv lub tsheb, tshem tawm cov yuam sij rau lub tsheb, thiab siv cov tshuaj tiv thaiv kab ntawv tam sim no tam sim no. Yog tias qhov kev ntws tam sim no los ntawm kev ntsuas yog nruab nrab ntawm 10-30ma, nws qhia tau tias lub tsheb tsis muaj xau. Ntawm qhov tsis sib xws, yog tias cov zaub loj dhau lawm, nws suav hais tias muaj tsheb nqos tsis taus. Nws yuav tsum raug sau tseg tias qee cov tshuab nqus ib qho tseem ceeb ntawm lub zog muaj zog li 15 feeb ntawm kev hloov tawm ntawm lub zog hloov. Yog li ntawd, yog tias qhov kev ntsuas tam sim no tau ntsuas kom tau 50ma saum toj no, nws yuav tsum tau sim dua tom qab 15 feeb. Yog tias nws tseem nyob saum 50MA nyob rau lub sijhawm no, nws qhia tau tias muaj tseeb tias muaj tseeb yog xav tau kev kuaj mob. Tom qab paub tseeb tias muaj ib qho xau nyob rau hauv lub tsheb lub cev, khaws cov tam sim no clamp khov kho rau ntawm lub teeb meem tsis zoo ntawm lub roj teeb. Koj tuaj yeem nqa tawm ib qho Fuses ib qho thaum soj ntsuam cov kev hloov pauv ntawm cov ntsuas tam sim no tus nqi. Yog tias tsis muaj kev hloov pauv ntawm cov ntsuas pom tom qab tshem tawm ib qho fuse, nws qhia tau tias cov dej xau tsis tshwm sim hauv qhov Circuit Court. Yog tias tus nqi tso tawm ntawm cov digital clamp ammeter rov qab los ua ib txwm muaj 10MA, nws qhia tau tias muaj qhov teeb meem tsis txaus ntseeg, uas yog qhov teeb meem hauv qab, uas muaj qhov teeb meem ntawm cov fuse.
(2) Cov khoom siv hluav taws xob sai
Los ntawm kev siv cov haujlwm ua haujlwm tam sim no, nws tseem tuaj yeem kuaj pom sai sai ntawm lub tsheb, xws li cov roj hluav taws xob, hluav taws xob thiab lub qhov rai motors, thiab cov tshuab hluav taws xob, tsis ua haujlwm. Piv txwv li, rau kev kuaj pom ntawm cov roj siv hluav taws xob, yog tias kev ua haujlwm tam sim no, yog tias muaj roj ntsha ua haujlwm li, nws yog tshwm sim los ntawm Circuit Coation * *; Yog tias cov haujlwm ua haujlwm tam sim no kuv tsawg dua 4.5A, nws qhia tau tias muaj cov roj hauv cov roj, thiab cov roj tsis muaj roj, ua kom muaj roj tsis muaj {{lead tam sim no; Yog tias kev ua haujlwm tam sim no kuv yog ntau dua 4.5A, nws qhia tau tias cov roj lim yuav txhaws, ua rau muaj kev nce ntxiv ntawm cov twj tso kua mis. Hauv qhov no, tsis zoo ntawm cov roj twj tso kua roj yog tshwm sim, thiab saib xyuas yuav tsum tau them thaum kuaj.
