1. Indlela yokunyanzeliswa kwepaneli isebenzisa umsebenzi wokutshintsha ngamnye kunye neqhosha elivezwe ngaphandle kwendawo yombane, i-console okanye umatshini ukujonga kunye nokugweba ngokufanelekileyo indawo yephutha.Umzekelo, isandi se-TV simane sizenzekele ngamanye amaxesha, kwaye iqhosha levolyum liyahlengahlengiswa ukuze livele“Nqakraza”isandi sikhatshwa sisandi esingaqhelekanga, ngoko ke kuyaziwa ukuba umthamo we-potentiometer unonxibelelwano olubi.
2. Indlela yokuhlola ngokuthe ngqo kukukhangela kunye nokugweba indawo yesiphoso ngokubona, ukuchukumisa, ukuva kunye nokuvumba.Le ndlela ifanelekile ngokukodwa kwiimpazamo ezicacileyo ezifana nokutshisa, iphunga elivuthayo, iphunga le-ozone kunye nesandi esingaqhelekanga.Umzekelo, kukho a“ukuqhekeka”isandi ngaphakathi kweTV emva kokuyivula, umfanekiso ugxuma ngesandi kunye nephunga elinamandla le-ozone livumba, ngoko kunokugwetywa ukuba i-transformer ye-line output okanye inxalenye ye-high-voltage iyavutha.
3. Indlela yokulinganisa i-voltage kukukhangela i-voltage yokubonelela kunye ne-voltage yamacandelo afanelekileyo ngokusetyenziswa kwe-multimeter, ngakumbi i-voltage kwiindawo eziphambili.Le ndlela yeyona ndlela isisiseko kwaye isetyenziswa ngokuqhelekileyo yokuhlola ukugcinwa kwezixhobo zendlu.
4. Indlela yokulinganisa yangoku yombane kukulinganisa umbane opheleleyo kunye nokusebenza kwangoku kwee-transistors kunye neengxenye ngokusebenzisa uluhlu olufanelekileyo lwangoku lwe-multimeter, ukwenzela ukuba ugwebe indawo ephosakeleyo ngokukhawuleza.Ngokomzekelo, i-TV isoloko itshiswa kunye ne-DC fuse kwaye i-total yangoku yonikezelo lwamandla olulinganiselweyo olulinganisiweyo lukhulu kunexabiso eliqhelekileyo, isiphaluka sesigaba sokuphuma komgca sinqanyuliwe kwaye ibuyela ngoku ibuyele yesiqhelo, ngoko kunokumiselwa ukuba impazamo. ikwinqanaba lokuphuma komgca kunye neesekethe ezilandelayo.
5. Indlela yokulinganisa ukuchasana kukugweba indawo ephosakeleyo ngokulinganisa ixabiso lokumelana nokuchasana, i-capacitance, i-inductance, i-coil, i-transistor kunye nebhloko edibeneyo.
6. Indlela ye-short-circuit ibhekisela kwindlela ye-AC ye-short-circuit, esebenza ngokukodwa ekunqumeni uluhlu lwesandi se-steamboat, isandi esikhalayo kunye nengxolo.Umzekelo, ukuba ufuna ukugweba impazamo yokukhala yerediyo, ungasebenzisa i-0.1μI-F capacitor kwi-short-circuit abaqokeleli be-tube yokuguqula, i-tube yokuqala yokukhulisa i-intermediate kunye neyesibini ityhubhu yokukhulisa i-intermediate emhlabeni, ngokulandelanayo.Ukukhala kuyanyamalala kwinqanaba elithile lesiphaluka esifutshane, iphoso lenzeka kweli nqanaba.
7. Indlela yokuqhawula isekethe kukucinezela uluhlu lwempazamo ngokusika isekethe ethile okanye ukukhupha icandelo elithile kunye neengcingo.Umzekelo, umsinga opheleleyo wesixhobo sombane mkhulu kakhulu, indawo ekrokrisayo yesekethe inokupheliswa kancinci kancinci.Impazamo iya kuba kwinqanaba apho i-current ibuyela kwisiqhelo xa inqanyuliwe.Le ndlela isoloko isetyenziselwa ukulungisa impazamo yangoku ngokugqithisileyo kunye nokutsha kwefuse.
8. Indlela yokunkqonkqoza kukugweba indawo yempazamo ngokusebenzisa isiphatho esincinci se-screwdriver okanye isando somthi ukunkqonkqoza ngobunono indawo ethile kwibhodi yesekethe kwaye uqwalasele imeko (Qaphela: ngokuqhelekileyo akulula ukunkqonkqoza indawo enevoltage ephezulu. ).Le ndlela ifanelekile ngokukhethekileyo ukujonga impazamo ye-welding yobuxoki kunye noqhagamshelwano olubi.Ngokomzekelo, akukho sandi kumfanekiso weTV ngamanye amaxesha, unokunkqonkqoza ngobunono kwiqokobhe leTV ngesandla sakho, kwaye impazamo ibonakala.Vula isiciko sangasemva seTV, khupha ibhodi yesekethe, kwaye unkqonkqoze ngobunono izinto ezikrokrisayo ngesiphatho se-screwdriver.Impazamo ikule ndawo apho impazamo ibonakala khona xa kunkqonkqozwa.
9. Ukutshintsha indlela yokuhlola kukutshintsha icandelo elithathwa njengelingalunganga ngokusetyenziswa kwecandelo elilungileyo.Le ndlela ilula kwaye kulula ukuyisebenzisa, kwaye ihlala ikhonakabini isiphumo ngesiqingatha somzamo..Ngokuqhelekileyo isetyenziselwa ukutshintsha i-tuner, i-transformer ye-line output, i-capacitor engaphantsi kwe-0.1μF, i-transistor, ibhloko edibeneyo kunye nokunye.
10. Indlela yokujova isignali kukufumana indawo ephosakeleyo ngokufaka umqondiso we-generator yesignali kwisiphaluka esiphosakeleyo.Le ndlela isetyenziswa ngokubanzi ukulungisa ingxaki enzima.
11. Indlela yokungenelela kukugweba indawo enempazamo ngokuthiusebenzisaindawo yentsimbi yescrewdriver kunye netweezers ukubamba iindawo ezifanelekileyo zokubona, jonga impendulo ye-clutter kwiscreen kwaye uve“Nqakraza”isandi sesigodlo.Le ndlela isoloko isetyenziselwa ukujonga itshaneli yoluntu, itshaneli yomfanekiso kunye nejelo lesandi.Umzekelo, akukho mfanekiso okanye impazamo yesandi efunyenweyo, thatha i-screwdriver ukuze uchukumise isiseko sokuqala sokukhulisa.Ukuba kukho impendulo ye-clutter kwisikrini kwaye uphondo lunayo“Nqakraza”isandi, ibonisa ukuba isiphaluka siqhelekile emva kokwandiswa okuphakathi, ngoko ke impazamo ikwi-tuner okanye i-eriyali.
12. Indlela yokuthelekisa kukufumana indawo ephosakeleyo ngokuthelekisa i-voltage, i-waveform kunye nezinye iiparitha zomatshini oqhelekileyo wemodeli efanayo kunye nomatshini ophosakeleyo.Le ndlela ifanelekileyo xa umzobo wesiphaluka ungafumaneki.
13. Indlela yokufudumeza kukukhawuleza ugwebe indawo yempazamo ngokufudumeza icandelo elikrokrisayo, ukuze kukhawuleziswe“ukufa”yecandelo elinjalo.Umzekelo, ububanzi bomgca weTV buqhelekile xa ivulwa nje, kwaye ububanzi bomgca burhoxa kwimizuzu embalwa kamva, iqokobhe letyhubhu yemveliso yomgca ijika ibe tyheli kwaye iculo lomgca lishushu, emva koko ungathatha i-soldering. intsimbi ukuya kwityhubhu yomgca ukuyitshisa.Ukuba ububanzi bomgca buqhubeka buhlanjululwa, kunokugwetywa ukuba ityhubhu yomgca inephutha.
14. Indlela yokupholisa kukukhawuleza ugwebe indawo yesiphoso ngokupholisa amacandelo akrokrelayo.Le ndlela isetyenziselwa impazamo eqhelekileyo, umzekelo, iqhelekile xa ivula, kodwa ingaqhelekanga emva kwexesha elithile.Xa kuthelekiswa nendlela yokufudumeza, ineenzuzo zokukhawuleza, ezifanelekileyo, ezichanekileyo kunye nezikhuselekileyo.Ngokomzekelo, i-amplitude yentsimi ye-TV iyinto eqhelekileyo emva kokuvula, kodwa iya kunyanzeliswa emva kwemizuzu embalwa kwaye yenze i-broadband ethe tyaba emva kwesiqingatha seyure, ityhubhu yokukhupha intsimi ivakalelwa kukuba ishushu xa ibanjwe ngesandla.Ngeli xesha, faka ibhola utywala kwityhubhu yemveliso yentsimi, kwaye intsimi ye-amplitude iqala ukunyuka kwaye iphosakele ngokukhawuleza, ngoko kunokugwetywa ukuba kubangelwa ukuzinza kwe-thermal ye-tube yemveliso yentsimi.
15. Indlela yokuhlola umzobo wenkqubo kukufumana indawo yesiphoso ngokunciphisa umda wesiphoso ngenyathelo ngokuhambelana nomzobo wenkqubo yokugcinwa kwempazamo.
16. Indlela ebanzi kukusebenzisa iindlela ezahlukeneyo ukujonga ezinye iimpazamo ezinzima.
