Izinyathelo Eziyisi-7 Zokuhlola Inzwa Yokucindezela Kwezintambo Ezingu-3

Ekupheleni kwalesi sihloko, uzokwazi ukuhlola inzwa yokucindezela kwezintambo ezintathu.

Ukuhlola inzwa yomfutho wezintambo ezi-3 kungaba luqili. Ekugcineni, kuzomele uhlole zonke izintambo ezintathu ukuthi azikho i-voltage. Lezi zintambo zinezintambo ezahlukene. Ngakho, ngaphandle kokuqonda okufanele nokubulawa, ungalahleka, yingakho ngilapha ukuze ngisize!

Ngokuvamile, ukuhlola inzwa yokucindezela kwezintambo ezi-3:

Setha i-multimeter ibe imodi yokulinganisa i-voltage.
Xhuma umkhondo omnyama we-multimeter kutheminali yebhethri eyinegethivu.
Xhuma i-probe ebomvu ye-multimeter ku-terminal eqondile yebhethri bese uhlola i-voltage (12-13 V).
Vula ukhiye wokuthungela endaweni ethi VULIWE (ungayiqalisi injini).
Thola inzwa yokucindezela.
Manje hlola izixhumi ezintathu zenzwa enezintambo ezintathu nge-multimeter probe ebomvu bese urekhoda ukufundwa.
Imbobo eyodwa kufanele ibonise i-5V kanti enye kufanele ibonise u-0.5V noma ngaphezulu kancane. Indawo yokugcina kufanele ibonise i-0V.

Ukuze uthole incazelo enemininingwane eyengeziwe, landela okuthunyelwe ngezansi.

Ngaphambi kokuthi siqale

Ngaphambi kokudlulela engxenyeni ephathekayo, kunezinto ezimbalwa okufanele uziqaphele.

Ukuqonda izintambo ezintathu kunzwa yokucindezela kungakusiza kakhulu lapho uhlola inzwa. Ngakho ake siqale ngalokhu.

Phakathi kwezintambo ezintathu, intambo eyodwa iyireferensi futhi enye intambo yesignali. Eyokugcina intambo yaphansi. Ngayinye yalezi zintambo ine-voltage ehlukile. Nansi eminye imininingwane mayelana nama-voltages abo.

Intambo yaphansi kufanele ibe ngu-0V.
Intambo yesithenjwa kufanele ibe ne-5V.
Uma injini icishiwe, intambo yesiginali kufanele ibe ngu-0.5V noma ngaphezulu kancane.

Lapho injini ivuliwe, ucingo lwesignali lubonisa i-voltage ebalulekile (5 nangaphansi). Kodwa ngizokwenza lokhu kuhlola ngaphandle kokuyiqala injini. Lokhu kusho ukuthi i-voltage kufanele ibe ngu-0.5 V. Ingase ikhuphuke kancane.

Ithiphu yosuku: Izintambo zenzwa yokucindezela ziza ngenhlanganisela yemibala ehlukene. Ayikho ikhodi yombala eqondile yalezi zintambo zezinzwa.

Yini i-Reverse Probing?

Indlela esiyisebenzisayo kule nqubo yokuhlola ibizwa ngokuthi i-reverse probing.

Ukuhlola ukusebenza kwamanje kwedivayisi ngaphandle kokuyinqamula kusixhumi kubizwa ngokuthi i-reverse probing. Lena indlela enhle yokuhlola ukwehla kwe-voltage yenzwa yokucindezela ngaphansi komthwalo.

Kule demo, ngizokuhamba ngendlela yokuhlola inzwa yokucindezela kwezimoto enezintambo ezi-3. Imoto iza nezinhlobo ezihlukahlukene zezinzwa zomfutho womoya, njengezinzwa zomfutho womoya, izinzwa zokucindezela kwesondo, izinzwa zokucindezela okuphelele, izinzwa zesitimela sikaphethiloli, njll. Isibonelo, inzwa yokucindezela komoya ithola umfutho womoya.(XNUMX)

Izinyathelo Eziyisi-7 Zokuhlola Inzwa Yokucindezela Kwezintambo Ezingu-3

Inzwa yesitimela sikaphethiloli iqapha umfutho kaphethiloli. Le nzwa itholakala endaweni okufinyeleleka kalula kuyo emotweni yakho. Ngakho-ke le nzwa yocingo olu-3 iyisinqumo esifanelekile salo mhlahlandlela. (2)

Isinyathelo 1 - Setha i-multimeter yakho kumodi ye-voltage

Okokuqala, setha i-multimeter kumodi ye-voltage engashintshi. Zungezisa ukudayela endaweni efanele. Amanye ama-multimeters anamandla okuzenzela kanti amanye awanawo. Uma kunjalo, setha i-span ku-20V.

Isinyathelo sesi-2 - Xhuma intambo emnyama

Bese uxhuma umkhondo omnyama we-multimeter kutheminali eyinegethivu yebhethri. Intambo emnyama kufanele ihlale kutheminali enegethivu kuze kuqedwe lokhu kuhlola. Ungasebenzisa lokhu kuxhumana njengesisekelo salokhu kuhlolwa.

Isinyathelo sesi-3 - Hlola umhlabathi

Bese uxhuma umkhondo obomvu we-multimeter kutheminali yebhethri ephozithivu bese uhlola ukufundwa.

Ukufundwa kufanele kube ngaphezu kwe-12-13V. Lena indlela enhle kakhulu yokuhlola isisekelo. Ungaphinda uhlole isimo sokuphakelwa kwamandla ngalesi sinyathelo.

Isinyathelo sesi-4 - Thola inzwa enezintambo ezi-3

Inzwa yesitimela se-fuel itholakala ngaphambi kwesitimela sikaphethiloli.

Isinyathelo sesi-5 - Vula ukhiye wokuthungela endaweni ethi VULIWE

Manje ngena emotweni bese uvula ukhiye wokuthungela endaweni ethi ON. Khumbula, ungayiqali injini.

Isinyathelo sesi-6 - Hlola izintambo ezintathu

Ngenxa yokuthi usebenzise indlela yokuhlehla yokuhlola, awukwazi ukunqamula izintambo kusixhumi. Kufanele kube nezikhala ezintathu ngemuva kwenzwa. Lezi zikhala zimelela ireferensi, isignali, nezintambo eziphansi. Ngakho, ungakwazi ukuxhuma ucingo multimeter kubo.

Thatha umkhondo obomvu we-multimeter bese uyixhuma kusixhumi sokuqala.
Bhala phansi ukufundwa kwe-multimeter.
Yenza okufanayo nakwezinye izikhala ezimbili ezisele.

Sebenzisa isiqeshana sephepha noma iphinikhodi yokuphepha lapho uxhuma ucingo olubomvu ezindaweni ezintathu zokukhala. Qinisekisa ukuthi i-paperclip noma iphinikhodi iyahamba.
