Bonisa indlela yokumelana nesikrini
Ngendlela yokuthola ukumelana kwesikrini esibonisiwe, sidinga ukusetha i-multimeter kububanzi bokumelana.Okokuqala, sidinga ukubona inani lokumelana ukusuka endaweni ethile ebhodini lesifunda elivamile kuya phansi, bese sidinga ukuhlola ukuthi kukhona umehluko phakathi kwephuzu elifanayo kwelinye ibhodi lesifunda kanye nenani elivamile lokumelana.Uma kukhona umehluko, sizokwazi ububanzi benkinga ngesikrini sokubonisa, ngaphandle kwalokho sizokuziba.
Bonisa indlela yokuthola amandla kagesi esikrinini
Ukutholwa kwe-voltage yesikrini esibonisiwe ukusetha i-multimeter kububanzi be-voltage, ukuthola i-voltage yaphansi yendawo yesifunda okusolwa ukuthi iyinkinga, bese uyiqhathanisa nedlule ukuze ubone ukuthi ijwayelekile yini.Ngale ndlela, inkinga ingabonakala kalula.
Indlela yokuthola isifunda esifushane sesikrini sokubonisa
Indlela yokuthola isekethe emfushane yesikrini iwukusetha i-multimeter kugiya lokuthola isekethe emfushane, ukuze kutholwe ukuthi kukhona yini ukwenzeka kwesekethe emfushane.Uma isifunda esifushane sitholakala, kufanele sixazululwe ngokushesha.Ukujikeleza okufushane esikrinini sokubonisa nakho kuyiphutha lemojula yesibonisi se-LED elivame kakhulu.Futhi!Ukutholwa komjikelezo omfushane kufanele kwenziwe lapho isekethe ivaliwe ukuze kugwenywe ukulimaza i-multimeter.
Bonisa indlela yokutholwa kokwehla kwamandla kagesi esikrinini
Indlela yokubona ukwehla kwamandla kagesi iwukulungisa i-multimeter ku-voltage ye-diode ukuze kutholwe i-downshift, ngoba wonke ama-IC esikrinini esibonisiwe akhiwe izingxenye eziningi zamayunithi, ngakho-ke uma kukhona okwamanje okudlula kuphini elithile, kuzoba nokwehla kwamandla kagesi. ephinini.Ngaphansi kwezimo ezijwayelekile, ukwehla kwamandla kagesi kumaphini we-IC wemodeli efanayo kuyafana.
Izindlela zokulungisa ezingenhla zezikrini zokubonisa ze-LED zingahlolwa ngokungavamile ukuze kugwenywe umonakalo esikrinini sokubonisa.Lokhu akugcini nje ukwandisa isikhathi sokusebenzisa kwayo, kodwa futhi konga izindleko zebhajethi ezingadingekile.Ngenxa yokuthi abanye abakhiqizi besikrini se-LED bahlinzeka kuphela ngesevisi yangemuva kokuthengisa unyaka owodwa kuya kwemibili, uma ukunakekelwa kwenziwa futhi ngemva kwalesi sikhathi sesevisi yangemuva kokuthengisa, kuzoba nenkokhiso eyengeziwe.
