Kwinkqubo yokukhusela izixhobo ze-elektroniki, izahlulo zidlala indima ebalulekileyo, yokubonelela ngokhuseleko xa isekenkene iqala iimeko ze-overvollicage.Nangona kunjalo, njengalo naliphi na elinye icandelo le-elektroniki, idrafti inokuva ubunzima ochaphazela ukusebenza kwesekethe yonke.Eli nqaku lijolise ekufumaneni iindlela zokufunyanwa komonakalo womtshato ukuze iingxaki zifumaneke ngokukhawuleza kwaye zithathwe amanyathelo okulungisa ngokuhambelana.
1. Ukuchongwa kwesahluko esonakalisiweyo
Umahluko, njengenxalenye yesikhuselo se-voltage ephambili, udlala indima ebalulekileyo kwizixhobo ze-elektroniki.Nangona bengakuthandi ukonakaliswa njengezinye izinto, ukuba kukho into engahambanga kakuhle, iziphumo zinokuba nzulu.Umonakalo kwi-vardistor ihlala ibonakalisa njengesekethe evulekileyo, ukunyuka kwamaxesha athile, ngelixa kuncipha ngenxa yokuxhathisa kunqabile.Zininzi iindidi zabaqengqelekayo, kubandakanywa abaqeqeshekiyo iifilimu, iifilimu zefilimu, oophindiso lwefilimu, kunye nabaphathi be-fusewound, kunye nabaphathi beFuse.Iindidi ezahlukeneyo zabaxhasi zineempawu ezahlukeneyo zokubonakala emva komonakalo.Umzekelo, abaphathi beengcingo zentambo banokuvela buthathaka okanye babe nemithambo-rocks, ngelixa abaphathi besamente banokuqhekeka xa batshiswe.Ukongeza, xa i-fuse yonakalisiwe, umphezulu wayo unokuyonakaliswe, kodwa ayiyi kutshiswa okanye ibe mnyama.
2. Ukulungiselela ngaphambi kovavanyo
Ngaphambi kovavanyondo, kufuneka lwenziwe amalungiselelo awaneleyo.Okokuqala, kuya kufuneka uqinisekise ukuba uvavanyo lukhokelela kwi-Multimeter kunye nezikhonkwane kuzo zombini iziphelo ze-Destints zixhunyiwe ngokuchanekileyo.Akukho mfuneko yokwahlula phakathi kokungathandekiyo nakwele nkqubo.Ukwenzela ukuphucula ukuchaneka kommiselo, uluhlu olufanelekileyo kufuneka lukhethwe ngokusekwe kwixabiso elifanelekileyo lokuchasana nokulinganiswa.Eli nyathelo libaluleke kakhulu kwinkqubo yovavanyo elandelayo, kuba ukhetho oluchanekileyo lunokuqinisekisa ukuchaneka kweziphumo zovavanyo.
3. Inkqubo yovavanyo lweenkcukacha
Inkqubo yokufunyanwa kwesanti inokwahlulwa ibe ngamanyathelo aliqela.Okokuqala, setha i-Mulb Fob kwi-gob yegiya yegiya kunye nesekethe ipeni yovavanyo.Ngeli xesha, kufuneka uqaphele ukuba isikhombisi se-Multimeter sibonisa ukuya kwi-zero.Ukuba akunjalo, kuya kufuneka uhlengahlengise i-OHM yeZero-ihlengahlengisa i-poomentameter de pointer ihambelana ne-zero.Okulandelayo, khetha ibhloko efanelekileyo yokukhulisa ngokusekwe kukunganyangeki komdlalo wokulinganisa.Eli nyathelo libalulekile kuba ukuchaneka kokufunda kwe-Multimeter kuchaphazeleka ngokuthe ngqo kukhetho lwe-lukhuni.Ekugqibeleni, emva kotshintsho lwegiya lokukhulisa, ukulungiswa kwenkqubo ye-zero yegiti yokunyangeka kufuneka kwenziwe kwakhona ukuqinisekisa ukuchaneka komlinganiso ngamnye.
