Erekana uburyo bwo kurwanya ecran
Kuburyo bwo guhangana nubushakashatsi bwerekana ecran, dukeneye gushiraho multimeter kurwego rwo guhangana.Ubwa mbere, dukeneye kumenya agaciro kokurwanya kuva kumwanya runaka kurubaho rusanzwe rwumuzunguruko kugeza hasi, hanyuma dukeneye gusuzuma niba hari itandukaniro riri hagati yikintu kimwe kurindi kibaho cyumuzunguruko nagaciro gasanzwe ko guhangana.Niba hari itandukaniro, tuzamenya urwego rwikibazo hamwe na ecran ya ecran, naho ubundi tuzabyirengagiza.
Erekana ecran ya voltage yo kumenya
Umuvuduko wa voltage yerekana ecran yerekana ni ugushiraho multimeter kurwego rwa voltage, ukamenya voltage yubutaka bwikibazo gikekwa cyumuzunguruko, hanyuma ukagereranya nicyambere kugirango urebe niba ari ibisanzwe.Ubu buryo, ikibazo kirashobora kumenyekana byoroshye.
Uburyo bugufi bwo gutahura uburyo bwo kwerekana ecran
Kugaragaza ecran mugufi uburyo bwo gutahura uburyo nugushiraho multimeter kubikoresho bigufi byerekana ibikoresho, kugirango umenye niba hari ibintu bigufi byumuzunguruko.Niba hari inzira ngufi ibonetse, igomba gukemurwa ako kanya.Inzira ngufi kuri ecran yerekana nayo ikunze kugaragara LED yerekana module ikosa.Nanone!Kumenya inzira ngufi bigomba gukorwa mugihe uruziga ruzimye kugirango wirinde kwangiza multimeter.
Erekana ecran ya voltage yamashanyarazi
Uburyo bwo kwerekana voltage yamashanyarazi ni uguhindura multimeter kuri diode voltage kugirango hamenyekane hasi, kubera ko IC zose ziri mugice cyo kwerekana zigizwe nibice byinshi bigize ibice, kuburyo mugihe hari umuyaga unyura kuri pin runaka, hazabaho igitonyanga cya voltage kuri pin.Mubihe bisanzwe, igabanuka rya voltage kuri IC pin ya moderi imwe irasa.
Uburyo bwo gufata neza hejuru ya LED yerekana ecran irashobora kugeragezwa muburyo budasanzwe kugirango wirinde kwangirika kwerekanwa.Ibi ntabwo byongera igihe cyo gukoresha gusa, ahubwo bizigama amafaranga yingengo yimari idakenewe.Kuberako LED yerekana ecran ikora gusa nyuma yo kugurisha kumwaka umwe cyangwa ibiri, niba kubungabunga byongeye gukorwa nyuma yiki gihe cyo kugurisha, hazaba hiyongereyeho amafaranga.
