Ungalihlola kanjani ibhethri nge-multimeter
Okuqukethwe
Ibhethri elifile ingenye yezinkinga ezivame kakhulu umnikazi wemoto abhekana nazo. Kudingeka ukuhlolwa kwebhethri ukuze kunqunywe ukuthi ibhethri idinga ukushintshwa yini.
Ngokuvamile kunzima ukuhlonza inkinga. Ithuluzi elishibhile elifana ne-multimeter yedijithali lingahlola ibhethri futhi likutshele ukuthi ibhethri yemoto yayo iphethe ishaji. I-multimeter ingaphinda ihlole ama-alternator, okungaba nomthelela omubi kubhethri lakho.
Kulesi sihloko, sizokusiza ukuthi unqume impilo yebhethri usebenzisa i-multimeter, futhi uphendule imibuzo elandelayo:
- Ngazi kanjani uma ibhethri lemoto yami lifile?
- Ngokuvamile, iyini impilo yebhethri?
- Kukuziphi izimo lapho kunganconywa ukusebenzisa i-multimeter ukuhlola ibhethri yemoto?
Mangaki amavolthi ebhethri lemoto?
Ngemva kokuhlola ibhethri, i-voltage ekahle kwibhethri yemoto kufanele ibe ngu-12.6 volts. Noma yini engaphansi kwama-volts angu-12 kuthathwa njengebhethri elifile noma eliphelile.
Izinyathelo zokuhlola ibhethri lemoto nge-multimeter
Ukuhlola amabhethri nge-multimeter kuyinqubo elula futhi ecatshangelwe kahle. Umphumela ukhombisa ukuthi ibhethri lemoto lidinga ukushajwa, noma sekuyisikhathi sokuvala elidala.
1. Khipha imali eyinsalela
Shiya umshini usebenza okungenani ihora ngaphambi kokuhlola ibhethri. Lokhu kuzokusiza ukuthi uthole ukufundwa kwe-voltage yebhethri enembe kakhulu.
Uma lokhu kungenzeki, khanyisa izibani imizuzu embalwa imoto icishiwe. Lokhu kuzosusa noma iyiphi inkokhiso eyinsalela uhlelo lukagesi lwemoto yakho okungenzeka inalo.
2. Lungisa i-multimeter yakho
Qiniseka ukuthi uthola inani elilungile lokuthi mangaki amavolthi kagesi ibhethri lemoto yakho elingawakhiqiza ngokumisa i-multimeter yedijithali ibe ngu-20 volts. Khetha i-voltage ephansi kakhulu engaphezu kuka-15 volts ku-DMM yakho uma i-DMM yakho ingenayo le voltage.
3. Thola ibhethri lemoto
Ukuze uhlole ibhethri lemoto, udinga kuqala wenze isiqiniseko sokuthi uyakwazi ukuthola ibhethri namatheminali alo. Ezimotweni eziningi, ibhethri itholakala ngaphansi kwe-hood endaweni yenjini ohlangothini olulodwa lwenjini. Nokho, kungase kube namabhethri esiqwini izimoto zanamuhla. Uma ungayitholi, ungabheka imanuwali yomnikazi wemoto yakho noma iwebhusayithi yomkhiqizi wemoto ukuze uyithole.
Amabhethri ezimotweni zesimanje anesembozo sepulasitiki okungase kudingeke usikhulule ukuze uthole ukufinyelela kumatheminali ebhethri. Qinisekisa ukuthi azikho izinto zensimbi, njengamathuluzi, ezihlangana namatheminali, njengoba zingafinyeza.
4. Xhuma i-multimeter iholela kumatheminali ebhethri.
Xhuma umthofu ngamunye we-DMM kumatheminali ebhethri yemoto u-negative ukuya ku-negative futhi uphozithivu ukuya kokuphozithivu. Kokubili i-multimeter nebhethri kunekhodi enemibala. Itheminali enegethivu kanye nophenyo kuzoba mnyama, futhi itheminali ephozithivu kanye nophenyo kuzoba bomvu. Uma ungakutholi ukufunda okuhle kwe-DMM, udinga ukukuhlehlisa.
Nakuba amanye ama-probe eyizicucu zensimbi ezingathinteka, ezinye ziyizinsimbi okufanele zixhunywe.
5. Hlola ukufunda
I-multimeter izokukhombisa ukufundwa. Ngicela uyibhale phansi. Okungcono, ngisho nangemva kokuvula izibani zangaphambili imizuzu engu-2, i-voltage kufanele isondele ku-12.6 volts, ngaphandle kwalokho ungase ube nebhethri elibi. Uma inani le-voltage lingaphezulu kuka-12.6 volts, lokhu kujwayelekile ngokuphelele. Uma ibhethri lehla liye ku-12.2 volts, ishajwa ngo-50% kuphela.
Noma yini engaphansi kwe-12 volts ibizwa ngokuthi ifile noma ikhishiwe.
Ngisho noma ibhethri lakho lishajwe kahle, kuwukuhlakanipha ukuhlola ukuthi imoto ingawadla yini amandla ngempumelelo.
6. Cela umuntu aqale injini
Okulandelayo, ngomkhondo we-multimeter exhunywe ebhethrini lemoto, cela umngane ukuthi avule ukuthungela imoto. Ngaphambi kokuqala imoto, qiniseka ukuthi imoto iphakathi nendawo futhi ibhuleki lokupaka livuliwe. Ngaphezu kwalokho, noma yimuphi umthofu we-multimeter akumele ulenga kumabhande anyakazayo noma ama-pulleys enjini.
Lona umsebenzi wabantu ababili; omunye kufanele aqaphe ama-oscillations we-multimeter, kanti omunye kufanele alawule ukuthungela. Zama ukungenzi konke lokhu ngokwakho, ngaphandle kwalokho ungarekhoda ukufundwa okungalungile.
7. Hlola ukufunda kwakho futhi
Okufanelekile, lapho imoto izama ukuqalisa, i-voltage kufanele iqale yehle ibe ngama-volts ayi-10. Uma ukufundwa kwehla ngaphansi kwama-volts angu-10 kodwa kuhlala ngaphezu kwama-volts angu-5, ibhethri izofa kancane futhi maduzane. Uma iwisa amanye ama-volts angu-5, sekuyisikhathi sokushintsha.
Ngaphezu kwalokho, lapho injini iqala, i-generator izokhipha okwamanje, futhi ukufundwa kwebhethri kuzoqala ukuphakama futhi. Ukufundwa kuzobuyela kunani eliphakeme cishe lama-volts angu-14 ngaphansi kwezimo ezifanele. (1)
Noma yiliphi inani elingaphandle kwalolu banga libonisa ibhethri elishajelwe kancane noma elishajwe ngokweqile. Ngakho-ke, i-alternator kufanele ihlolwe ngaphandle kwalokho izolimaza ibhethri lemoto yakho.
Yiziphi izimpawu zebhethri yemoto embi?
Ungase ube nezinkinga ezilandelayo ezibonisa ibhethri elingalungile:
- Ibhethri eliphansi kusibonisi sedeshibhodi
- Chofoza injini uma uvula imoto
- Isidingo sokugxuma njalo
- Ukushisa okubambezelekile
- Izibani zangaphambili azikhanyi, zifiphele futhi azikwazi ukumelana nokusebenza imizuzu emi-2.
Ibhethri lemoto kufanele lihlale isikhathi esingakanani?
Amabhethri amaningi ezimoto anewaranti yeminyaka emine, kodwa angase angahlali isikhathi eside kangako. Ngokuvamile zikhonza iminyaka engu-3-4, emva kwalokho kufanele zishintshwe ezintsha.
Ngingakwazi nini ukusebenzisa i-multimeter ukuhlola ibhethri lemoto?
Uma ungenawo amabhethri angalondolozi, ungasebenzisa i-hydrometer ukuhlola lawa mabhethri emoto. Uma ufuna ukuzibona, amabhethri anganakekeli anamakepisi epulasitiki kuseli ngayinye. (2)
Isinqumo sokugcina
Awudingi usizo lochwepheshe ukuze uqedele izinyathelo ezingenhla, futhi ukuhlola ibhethri lakho nge-multimeter kungenye yezindlela ezilula nezishibhe kakhulu.
