Izikrini zokubonisa ze-LEDbabe nezici ezifana nokuvikelwa kwemvelo, ukukhanya okuphezulu, ukucaca okuphezulu, nokuthembeka okuphezulu.Ngokuthuthuka kobuchwepheshe, izikrini zokubonisa ze-LED zisetshenziswe kabanzi.Ngezansi, sizokwethula izindlela zokuhlola ezivame ukusetshenziswa zokulungisa izikrini zokubonisa i-elekthronikhi ze-LED, ngethemba lokuba usizo kuwo wonke umuntu.
01 Indlela yokuthola isifunda esifushane
Setha i-multimeter ku-isifunda esifushaneimodi yokuthola (imvamisa ngokusebenza kwe-alamu, uma i-conductive, izokhipha umsindo we-beep) ukuze kutholwe ukuthi kukhona ukujikeleza okufushane.Uma isifunda esifushane sitholakala, kufanele sixazululwe ngokushesha.Ukujikeleza okufushane futhi kuyiphutha lemojula yesibonisi se-LED elivame kakhulu.Ezinye zingatholakala ngokubheka izikhonkwane ze-IC namaphinikhodi.Ukutholwa komjikelezo omfushane kufanele kwenziwe lapho isekethe ivaliwe ukuze kugwenywe ukulimaza i-multimeter.Le ndlela isetshenziswa kakhulu, ilula futhi iyasebenza.Amaphesenti angama-90 amaphutha angabonwa futhi ahlulelwe ngale ndlela.
02 Indlela yokutholwa kokumelana
Setha i-multimeter ebangeni lokumelana, hlola inani lokumelana nomhlaba endaweni ethile ebhodini lesifunda elivamile, bese uhlola ukuthi ukhona yini umehluko phakathi kwephuzu elifanayo kwelinye ibhodi lesifunda elifanayo kanye nenani elivamile lokumelana.Uma kukhona umehluko, ububanzi benkinga bunqunywa.
03 Indlela yokuthola amandla kagesi
Setha i-multimeter kububanzi be-voltage, thola i-voltage yaphansi endaweni ethile endaweni okusolekayo, qhathanisa ukuthi iyafana yini nevelu evamile, futhi unqume kalula ububanzi benkinga.
04 Indlela yokuthola ukwehla komfutho
Setha i-multimeter kumodi yokutholwa kokwehla kwe-voltage ye-diode, njengoba wonke ama-IC akhiwe izingxenye eziningi eziyisisekelo eziyisisekelo, ezenziwe nge-miniaturized kuphela.Ngakho-ke, uma kukhona okwamanje okudlula kwenye yezikhonkwane zayo, kuzoba nokwehla kwe-voltage kumaphini.Ngokuvamile, ukwehla kwamandla kagesi kumaphini afanayo wemodeli efanayo ye-IC kuyefana.Kuye ngenani le-voltage drop drop on the pins, kuyadingeka ukusebenza lapho isifunda sivaliwe.
