Uvavanyo lwebhetri yefowuni

intshayelelo

Uvavanyo lwebhetri yefowuni lubhekisa kumsebenzi ovavanya umthamo webhetri yefowuni. Ngokulinganisa i-voltage kunye ne-current yebhetri, kunokugwetywa ukuba ibhetri inesiphene okanye hayi.

Amanyathelo okuvavanya ibhetri yefowuni

1. Susa ibhetri kwifowuni yakho

Umvavanyi webhetri wefowuni olula ufuna kuphela ibhetri ukuba ifakwe kwisixhobo ukuvavanya amandla ayo.

2. Qhagamshela ibhetri yefowuni yakho

Abavavanyi abahlukeneyo basebenzisa iindlela ezahlukeneyo zokudibanisa, kodwa kwiimeko ezininzi, isixhobo esenziwe kakuhle siya kuba neeprobe zetsimbi ezi-2 ezinokuchukumisa iziqhagamshelo kuzo zombini iziphelo zebhetri ngaxeshanye xa zingaqhotyoshelwanga kwifowuni.

3. Funda isiphumo soVavanyo lwebhetri yefowuni

Emva kokudibanisa ibhetri yefowuni yakho kwisixhobo, funda imveliso eboniswa zii-LEDs okanye isikrini seLCD kwisixhobo ngokwevoltheji kunye nokufundwa kwangoku. Kwiimeko ezininzi, ixabiso eliqhelekileyo elidweliswe kuwo omabini amaxabiso kufuneka libe malunga ne-3.8V kunye ne-0-1A.

I-Multimeter yoVavanyo lwebhetri yefowuni

Amanyathelo okudibanisa ibhetri yefowuni kwi-multimeter

1. Khupha ibhetri kwifowuni

I-multimeter ngokuqhelekileyo ikwimo yesixhobo esincinci. Ekuphela kwento ekufuneka uyenzile kukukhupha ibhetri yefowuni yakho kwifowuni yakho emva koko uyibeke kwisokethi engasemva kwemultimeter.

2. Khanyisa umbane

Kukho iindlela ezi-2 zokuvula umhloli webhetri yeselula / i-multimeter, enye kukuvula iqhosha lamandla, enye kukucofa iqhosha elikhethekileyo lomsebenzi. Amanyathelo athile anokwahluka kwizixhobo ezahlukeneyo. Nangona kukho imiqathango okufuneka uyibeke ingqalelo: okokuqala, musa ukuchukumisa iiprobe zetsimbi ze-multimeter ngesandla sakho kuba ziya kukhokelela kwiziphumo ezingalunganga.

3. Funda isiphumo

Iziphumo zovavanyo lwebhetri yefowuni ziya kuboniswa kwiscreen seLCD semultimeter emva kokuba uyitshintshele kumbane okanye umsebenzi wangoku. Kwiimeko ezininzi, ixabiso eliqhelekileyo kufuneka libe malunga ne-3.8V kunye ne-0-1A.

Izibonelelo zoVavanyo lwebhetri yefowuni

1. Ukulinganisa i-voltage kunye ne-current yebhetri ingabonisa ukuba inesiphene okanye hayi. Uninzi lweebhetri eziqhelekileyo zinevoltage ephezulu kunaleyo yaboniswa xa ibhetri yayithengwe okokuqala kuba ekuhambeni kwexesha izakwehla kancinci ngenxa yokusetyenziswa kunye nokuguga.
2. Ukuvavanya ibhetri yefowuni kukuvumela ukuba ufumane ukuba iingxaki zamandla efowuni yakho kunye nokungasebenzi kakuhle kubangelwa yi-hardware yefowuni okanye ibhetri yayo. Oku kuluncedo kuba ukuba ibhetri efuna ukutshintshwa, kufuneka ufumane entsha endaweni yokuchitha ixesha kunye nemali kwezinye iindlela.
3. Uvavanyo lwebhetri yefowuni lunokunceda ukwandisa ubomi bebhetri yesixhobo sakho ngokusebenzisa iindlela ezichanekileyo zokuqonda ukuba angakanani amandla akhutshwa yifowuni yakho. Oku kunokuphunyezwa ngokubeka esweni umsinga otsalwa kwibhetri kusetyenziswa iammeter, okanye ukulinganisa amandla ombane kwisixhasi esithile esine-voltmeter ukubala amandla (IVoltge x yangoku = Amandla).

isiphelo

Umsebenzi ophambili wovavanyo lwebhetri yefowuni kukuvavanya umthamo webhetri yefowuni. Nangona kunjalo, eminye imisebenzi inokwenziwa yi-multimeter efana nokuvavanya iisekethe zedijithali kunye nokujonga ukuba kukho nayiphi na isekethe emfutshane okanye impazamo yokumisa kwi-wiring, kunye nokunye okuninzi.
