Izikrini zokubonisa i-LEDzineempawu ezifana nokukhuselwa kwendalo, ukukhanya okuphezulu, ukucaca okuphezulu, kunye nokuthembeka okuphezulu.Ngokuhambela phambili kwetekhnoloji, izikrini zokubonisa i-LED zisetyenziswe ngokubanzi.Ngezantsi, siza kwazisa iindlela zokuhlola ezisetyenziswa ngokuqhelekileyo ukulungisa izikrini zokubonisa i-LED, ngethemba lokuba luncedo kuwo wonke umntu.
01 Indlela yokubona isiphaluka esifutshane
Seta i-multimeter kwiintambo emfutshaneindlela yokufumanisa (ngokuqhelekileyo kunye nomsebenzi we-alarm, ukuba i-conductive, iya kukhupha isandi se-beep) ukufumanisa ukuba kukho isiphaluka esifutshane.Ukuba isiphaluka esifutshane sifunyenwe, kufuneka sisonjululwe ngokukhawuleza.Isiphaluka esifutshane sesona siphoso semodyuli ye-LED eqhelekileyo.Ezinye zinokufunyanwa ngokujonga izikhonkwane ze-IC kunye nezikhonkwane.Ukufumanisa isiphaluka esifutshane kufuneka kuqhutywe xa isiphaluka sivaliwe ukuphepha ukulimaza i-multimeter.Le ndlela yeyona isetyenziswa ngokuqhelekileyo, ilula kwaye iyasebenza.I-90% yeempazamo inokubonwa kwaye igwetywe ngale ndlela.
02 Indlela yokubona ukuchasa
Cwangcisa i-multimeter kuluhlu oluchasayo, uvavanye ixabiso lokumelana nomhlaba kwinqanaba elithile kwibhodi yesiphaluka esiqhelekileyo, uze uvavanye ukuba kukho umehluko phakathi kwendawo efanayo kwenye ibhodi yesiphaluka esifanayo kunye nexabiso eliqhelekileyo lokumelana.Ukuba kukho umahluko, uluhlu lwengxaki luchongiwe.
03 Indlela yokubona umbane
Misela i-multimeter kuluhlu lwe-voltage, fumana i-voltage yomhlaba kwindawo ethile kwisiphaluka esikrokrelwayo, thelekisa ukuba iyafana nexabiso eliqhelekileyo, kwaye unqume ngokulula uluhlu lwengxaki.
04 Indlela yokubona uxinzelelo lwehla
Cwangcisa i-multimeter kwimowudi yokufumanisa ukuhla kombane wediode, njengoko zonke ii-ICs zenziwe ngezinto ezininzi ezisisiseko ezisisiseko, zincinci kuphela.Ngoko ke, xa kukho ngoku kudlula enye yezikhonkwane zayo, kuya kubakho ukuhla kwamandla ombane kwizikhonkwane.Ngokubanzi, ukuhla kwamandla ombane kwizikhonkwane ezifanayo zemodeli efanayo ye-IC kuyafana.Ngokuxhomekeke kwixabiso le-voltage drop drop on the pins, kuyimfuneko ukusebenza xa isiphaluka sivaliwe.
