Ungahlola kanjani ukushintshwa kwewindi lamandla nge-multimeter?

Ingabe uzama ukuxazulula inkinga yokuthi kungani amawindi akho kagesi engasebenzi futhi ucabanga ukuthi kungenzeka ukuthi ubhekene neswishi yamandla ephukile? Iningi lethu lihlangabezana nale nkinga izikhathi ngezikhathi emotweni endala. Kungakhathaliseki ukuthi unomshini oshintshashintshayo ozenzakalelayo noma owenziwe ngesandla, kuzodingeka ukulungise lokhu ngokushesha okukhulu.

Ukushintsha kwewindi okuphukile kungabangela umonakalo omkhulu wangaphakathi esimweni sezulu esinemvula noma seqhwa uma ungakwazi ukuvala amawindi akho.

Ngakho-ke, uma ubhekene nenkinga efanayo futhi ufuna ukuthola ukuthi ukushintshwa kwakho kuyinkinga yini, lesi siqondisi sezinyathelo ezingu-6 sendlela yokuhlola ukushintshwa kwewindi lakho lamandla usebenzisa i-multimeter kuzokusiza.

Ukuze uhlole iswishi yamandla ewindini, qala ngokususa ikhava yomnyango. Bese uhlukanisa iswishi yamandla ezintanjeni. Setha i-multimeter kumodi yokuqhubeka. Bese uxhuma i-probe emnyama kutheminali eyinegethivu yeswishi yamandla. Hlola wonke amatheminali ngokuqhubekayo usebenzisa i-probe ebomvu.

Okujwayelekile kakhulu? Ungakhathazeki, sizokumboza kabanzi lokhu ezithombeni ezingezansi.

Umehluko phakathi komshini wokushintsha othomathikhi kanye nowokwenziwa ngesandla

Izimoto zesimanje ziphuma namawindi asebenza ngogesi amabili ahlukene. Ukuqonda kahle lezi zindlela ezimbili zokushintsha kuzokusiza kakhulu uma wenza ukuguqulwa kwewindi lamandla okuzenzakalelayo noma ukulungisa iwindi lamandla. Ngakho nanka amanye amaqiniso ngalezi zindlela ezimbili.

Imodi ezenzakalelayo: Iswishi yewindi lamandla azenzakalelayo iqala ukusebenza ngokushesha nje lapho ukhiye wokubasa wemoto uvuliwe.

Imaniwali yosebenzisayo: I-manual shift mechanism iza ne-crank yewindi ekwazi ukusetshenziswa mathupha.

Izinto Ezimbalwa Ongazizama Ngaphambi Kokuhlola Ukushintshwa Kwewindi Lakho Lamandla

Uma iwindi lamandla lishintsha ukungasebenzi kahle, ungaqali ngokushesha ukuhlola ukuqhubeka kwesekethe. Nazi izinto ezimbalwa ongazihlola ngaphambi kokuhlola ngempela.

Isinyathelo 1: Hlola wonke amaswishi

Ngaphakathi kwemoto yakho, uzothola iphaneli yokushintsha iwindi lamandla amakhulu eduze kwesihlalo somshayeli. Ungavula/uvale wonke amawindi kuphaneli enkulu. Ngaphezu kwalokho, kukhona amaswishi emnyango ngamunye. Ungathola okungenani amafasitela anamandla ayisishiyagalombili phakathi kwemoto yakho. Hlola wonke amaswishi ngendlela efanele.

Isinyathelo sesi-2: Hlola iswishi yokukhiya

Ungathola inkinobho yokukhiya kuphaneli yokushintsha iwindi lamandla, etholakala eduze kwesihlalo somshayeli. Iswishi yokukhiya izokunikeza amandla okukhiya ngaphandle wonke amanye amaswishi ewindi lamandla ngaphandle kwamaswishi ephaneli yokushintsha iwindi lamandla amakhulu. Lona ukhiye wokuphepha ongabangela izinkinga ngezinye izikhathi ngokushintsha kwewindi lamandla. Ngakho-ke, hlola ukuthi iswishi yokukhiya ivuliwe yini.

6 Isinyathelo Umhlahlandlela Wokuhlola Iwindi Lokushintsha Amandla

Ngemva kokuhlonza kahle amaswishi akho ewindi lamandla aphukile, manje ungaqala inqubo yokuhlola. (1)

Isinyathelo 1 - Khipha Ikhava Yomnyango

Okokuqala, kufanele ukhulule izikulufi ezibambe isembozo endaweni. Sebenzisa i-screwdriver kule nqubo.

Bese uhlukanisa ikhava nomnyango.

Isinyathelo sesi-2 - Khipha inkinobho yamandla

Ngisho noma ususa izikulufu ezimbili, ikhava neswishi yamandla kusaxhunywe emnyango ngezintambo. Ngakho-ke, udinga ukunqamula lezi zintambo kuqala. Ungakwenza lokhu ngokucindezela i-lever etholakala eduze kocingo ngalunye.

Ngemva kokunqamula izintambo, khipha iswishi yamandla. Uma ukhipha iswishi yamandla, kufanele uqaphele kancane ngoba kunezintambo ezimbalwa ezixhuma ikhava kanye nesishintshi samandla. Ngakho qiniseka ukuthi uyawacisha. 

Isinyathelo sesi-3: Setha i-DMM ukuze uhlole ukuqhubeka.

Ngemuva kwalokhu, setha i-multimeter kumodi yokudayela. Uma ungazange usebenzise i-multimeter ukuhlola ukuqhubeka, nansi indlela ongayenza ngayo.

Ukusetha i-multimeter ukuhlola ukuqhubeka

Ukusetha kulula futhi kuthatha umzuzu owodwa noma emibili kuphela. Guqula ukudayela kwe-multimeter kube i-diode noma uphawu lwe-Ω. Lapho ama-probes amabili exhunywe kumjikelezo ovaliwe, i-multimeter ikhipha i-beep eqhubekayo.

Ngendlela, isifunda esivaliwe yisifunda lapho kugeleza khona okwamanje.

Ithiphu: Uma uvule ngempumelelo imodi yokuqhubeka, i-multimeter izoveza izimpawu ze-Ω ne-OL. Futhi, qiniseka ukuthi uthinta ama-probe amabili ukuze uhlole ibhiphu. Lena indlela enhle yokuhlola i-multimeter yakho ngaphambi kokuthi uqale.

Isinyathelo sesi-4: Hlola iswishi yamandla ngomonakalo.

Kwesinye isikhathi iswishi yamandla ingabambeka ngendlela engenakulungiseka. Uma kunjalo, kungase kudingeke ukuthi esikhundleni salo ufake iswishi yamandla entsha. Asikho isidingo sokuhlola iswishi yamandla ebambekile. Ngakho-ke, hlola inkinobho yamandla kahle ukuze uthole izindlela zokunamathela noma ezinephutha.

Isinyathelo sesi-5 - Amatheminali okuhlola

Manje xhuma i-probe emnyama kutheminali enegethivu yokushintshwa kwamandla. Gcina lokhu kuxhumana uze uhlole wonke amatheminali. Ngakho-ke, sebenzisa isiqeshana sengwenya ukuze uxhume uphenyo olumnyama kutheminali.

Bese ubeka i-probe ebomvu kutheminali efanele. Hambisa inkinobho yewindi lamandla endaweni "yewindi eliphansi". Hlola ukuthi i-multimeter iyakhala yini. Uma kungenjalo, setha ukushintshwa kwamandla endaweni "yokuvula iwindi". Bheka futhi ibhiphu lapha. Uma ungezwa ibhiphu, setha iswishi sibe maphakathi. Hlola wonke amatheminali ngokwenqubo echazwe ngenhla.

Uma ungezwa ibhiphu yazo zonke izilungiselelo namatheminali, kusho ukuthi iswishi yewindi lamandla iphukile. Kodwa-ke, uma uzwe ibhiphu yendawo ephansi yewindi futhi kungekho lutho lwendawo yokukhuphuka kwewindi, lokho kusho ukuthi ingxenye eyodwa yokushintsha kwakho iyasebenza kanti enye ayisebenzi.

Isinyathelo sesi-6: Vula iswishi yamandla endala noma uyishintshe ufake entsha.

Akunandaba ukuthi usebenzisa iswishi endala noma entsha; Inqubo yokufaka iyafana. Ngakho-ke, xhuma amasethi amabili ezintambo ekushintsheni, beka inkinobho kukhava, bese uyinamathisela kukhava. Ekugcineni, qinisa izikulufu ezixhuma ikhava nomnyango.

Ukufingqa

Ekugcineni, ngithemba ngempela ukuthi manje usunombono ofanele wokuthi ungavivinya kanjani iswishi sakho sewindi lamandla usebenzisa i-multimeter. Inqubo ayiyona neze inkimbinkimbi. Kodwa uma umusha ekwenzeni lezi zinto ngokwakho, khumbula ukuqaphela kakhulu phakathi nale nqubo. Ikakhulukazi uma ukhipha iswishi yamandla kukhava nomnyango. Isibonelo, ukushintshwa kwewindi lamandla kunezintambo ezimbalwa ezixhunywe kuyo nhlangothi zombili. Lezi zintambo zingagqashuka kalula. Ngakho-ke, qiniseka ukuthi lokhu akwenzeki. (2)
