Ungavivinya Kanjani Izibani Ze-trailer Nge-Multimeter (Umhlahlandlela)

Kubaluleke kakhulu ukuthi ukukhanya kwe-trailer yakho kusebenze kahle. Ukushayela ngaphandle kwazo kubeka impilo yakho kanye neyabanye engozini. Nokho, ngisho noma ubanakekela, ngokuvamile bayayeka ukusebenza.

Ngezansi sihlanganise umhlahlandlela wokuthi ungavivinya kanjani izibani ze-trailer nge-multimeter. Lokhu kuzokusiza ukuthi uvimbele amaphutha esikhathi esizayo futhi wenze umsebenzi wenziwe ngokunembe kakhudlwana.

Kungani isibani se-trailer singasebenzi?

Ukufakwa phansi okungalungile kubangela izinkinga eziningi zezintambo zama-trailer. Ngokuvamile ucingo olumhlophe luphuma kusixhumi se-trailer. Izibani zingase zisebenze njalo noma zingasebenzi nhlobo uma umhlabathi umpofu.

Ngisho noma i-wiring esokhethi ifanelekile, hlola isisekelo kuhlaka lwe-trailer. Kufanele icwebezele futhi ihlanzeke, ingapendeki futhi ingagqwali, futhi ilungiswe kahle. Uma usebenzisa isignali eyodwa yokujika futhi ivuliwe kodwa ingakhanyi ngendlela okufanele ibe ngayo, sola indawo.

Ungahlola kanjani izibani ze-trailer nge-multimeter

Ngokuvamile, ukuchayeka kwe-trailer odakeni, eqhweni, emvuleni, elangeni, nasesihlabathini kungalimaza ukukhanya kwe-trailer, njengoba lokhu kunomthelela ekwakhiweni kokukhubazeka okuhlukahlukene kobuchwepheshe. Ngenxa yalokho, kufanele uhlale uhlola ukuthi izibani ze-trailer yakho zisebenza kahle yini. 

No. 1. ukuhlolwa kokuxilonga

Ngaphambi kokukhipha i-multimeter, hlola inkinga ngoxhumo, hhayi enye into. Kwenziwa kanjani? 

• Shintsha ama-bulb kuqala, njengoba lokhu kungase kube umthombo wenkinga, hhayi izibani ze-trailer.
• Uma namanje kungasebenzi, inkinga ingase ibe ngezintambo.
• Susa izintambo ezixhuma imoto enkulu ku-trailer. 
• Namathisela izibani zangaphambili ngqo ku-trailer ukuze uhlole lokhu.
• Uma izinkomba zingasebenzi, uzodinga ukusebenzisa i-multimeter.

#2 Ground Test

Manje udinga ukuhlola umhlaba nge-multimeter.

• Bamba imikhondo emibili ye-multimeter, emnyama nebomvu noma engemihle kanye nephozithivu ngokulandelana.
• Ukuze uhlole ukubeka phansi, i-multimeter kufanele isethwe ku-ohms noma ukumelana.
• Xhuma izinzwa ukuze uqinisekise ukuthi ziyasebenza.
• Xhuma i-probe ebomvu phansi kanye nosesho olumnyama kutheminali enegethivu. I-multimeter kufanele ifunde mayelana ne-0.3 ohms.

No. 3. Ukuhlolwa kwamapulagi e-trailer

Ngemva kokuhlola umhlabathi nokuthola ukuthi lokhu akuyona inkinga, kufanele uqhubeke uhlole ipulaki ye-trailer. Lokhu kuyadingeka ukuze kuqinisekiswe ukuthi i-voltage edingekayo iyatholakala. Futhi, qiniseka ukuthi uyasiqonda isixhumi sakho nazo zonke izintambo ukuze ugweme ukudideka. Ukwenza kanjalo kungase kubangele ingozi noma ukuhlinzwa okunephutha. Ngakolunye uhlangothi, amanye ama-multimeters avame ukulebula, kuyilapho amanye enamakhodi ombala ahlukene. (1)

Ukwenza ukuhlolwa kwepulaki ye-trailer.

• Setha i-multimeter ibe ngamavolthi wamanje oqondile (DC) bese uyixhuma kumthofu ongemuhle omnyama. 
• Xhuma intambo ephambene kutheminali ephozithivu bese ukhanyisa isibani esilawulwa yileyo phini.
• Uma i-multimeter ibonisa inani elifanayo lama-volts njengoba ipulaki ihlolwa, lelo pulaki akuwona umthombo wenkinga.

Isibonelo, uma unamathisela i-probe yakho ebomvu kusilawuli sesandla sobunxele se-transmitter, kufanele uvule ukukhanya kwayo. Njengomphumela, i-multimeter yakho izokhombisa cishe ama-volts ayi-12. Uma iqhubeka nokubonisa lokhu ngemva kokuhlola kabusha, kusho ukuthi amapulaki e-trailer spark asebenza kahle.

No. 4. Ukuhlolwa kwe-voltage

Lokhu ukuhlola i-voltage uma ungakayitholi inkinga ngaphambilini.

• Hlola uxhumano lwakho ukuze unqume ukuthi yiziphi izintambo eziya kukuphi ukukhanya. Njengomthetho, kunezintambo ezine ezinemibala ehlukene kanye nocingo olumhlophe lomhlabathi.
• Setha ukusetha i-voltage ku-multimeter ukuze ulinganise i-voltage. Qiniseka ukuthi isethelwe ukukala kokubili i-DC ne-AC yamanje. Umugqa oqondile usetshenziselwa ukumela umugqa oqondile.
• Xhuma isivivinyo esimnyama esiholela kutheminali enegethivu futhi ukuhlola okubomvu kuholele kwenye yezintambo ezikhanyayo. Bese ukhanyisa isibani.
• Naka ukufunda. I-multimeter yakho kufanele ibonise inani elifana ne-voltage yebhethri oyisebenzisayo. Ngakho-ke uma ibhethri lingu-12 volts, ukufundwa kufanele kube ngama-volts angu-12.

Inombolo 5. Ukuhlolwa Kokukhanyisa Isixhumi

Kufanele ulinganise ukumelana ukuze uhlole uxhumano lokukhanyisa. Ukuze wenze lokhu, landela izinyathelo ezinikezwe ngezansi:

• Qinisekisa ukuthi i-multimeter isethelwe ukukala ukumelana (ohms).
• Xhuma i-multimeter iholela ku-multimeter.
• Xhuma i-probe ebomvu endaweni ngayinye ethintwayo kanye nophenyo olumnyama phansi.
• Naka ukufunda. Uma inani lingu-3 ohms, isistimu yakho yezintambo isebenza kahle. (2)

Kodwa-ke, ukufaka izintambo, njengokunika amandla amalambu okujika namalambu okubhaka, kudinga ukulawula okungaphezu kokukodwa. Futhi, khumbula ukuthi lezi zintambo ziqukethe ukulandelana kokuxhumana. I-multimeter yakho kungenzeka ibika ukufunda okuphansi kokumelana.

Ukuze ugweme izinkinga, hlukanisa lezi zintambo ngokukhipha ama-bulb futhi uhlole ngayinye ngayinye. Ukuze uhlaziye isignali efanele, khulula izibani zamabhuleki ukuze i-multimeter ifunde amasignali alungile kuphela. Phinda le ndlela kwezinye izibani, uqophe idatha ebonisiwe.

Ukufingqa

Ngemva kokufunda lesi sihloko, kufanele wazi ukuthi ungahlola kanjani izibani ze-trailer nge-multimeter. Ngenxa yalokho, awudingi ukukhathazeka ngembangela yokwehluleka kwezibani ze-trailer yakho.

Ezinye izifundo ze-multimeter zingezansi. Kuze kube isihloko sethu esilandelayo!

• Ungahlola kanjani izimbali zikaKhisimusi nge-multimeter
• Isetshenziswa Kanjani I-Cen-Tech Digital Multimeter ukuze Uhlole I-Voltage
• Ungakala kanjani ama-amps nge-multimeter
