Yadda ake Gwada ECU tare da Multimeter (Jagorar Mataki na 4)

Motar ku na iya rushewa kuma ta tsaya saboda dalilai daban-daban, gano waɗannan matsalolin yana da mahimmanci don gyara su. Matsalar na iya zama ECU sosai. Amma yadda za a duba shi? 

Don gwada ECU tare da multimeter, kuna buƙatar bi matakai 4 masu sauƙi: 1. Saita multimeter, 2. Gudanar da dubawa na gani, 3. Haɗa kuma bi jagororin gwaji, 4. Yi rikodin karatun.

Kunya? Kar ku damu, zan yi bayani dalla-dalla a kasa.

Yadda ake duba kwamfutar da multimeter

Anan akwai matakai 4 masu sauƙi don bi yayin duba ECU tare da multimeter:

Mataki 1: Saita multimeter

Multimeter ya ƙunshi manyan sassa 3:

- Nuni

– Kullin zaɓi

- Tashar jiragen ruwa

M nuni multimeter yana da lambobi huɗu kuma ikon nuna alamar mara kyau. 

Hannun mai zaɓe yana bawa mai amfani damar saita multimeter don karanta dabi'u daban-daban kamar na yanzu (mA), ƙarfin lantarki (V) da juriya (Ω). Dole ne mu toshe na'urorin multimeter guda biyu a cikin tashoshin jiragen ruwa a kasan nunin na'urar. Akwai bincike guda biyu, baƙar fata da kuma jan bincike.

An haɗa firikwensin launi zuwa Com tashar jiragen ruwa (gajeren gama gari), jan bincike yawanci ana haɗa shi da mA ohm port. Wannan tashar jiragen ruwa na iya auna igiyoyi har zuwa 200 mA. Anan V yana nufin ƙarfin lantarki da juriya Ω. Akwai kuma tashar jiragen ruwa 10 A, wanda shi ne tashar jiragen ruwa na musamman wanda zai iya auna fiye da 200mA.

farko matakai

Na gaba, saita multimeter don auna ƙarfin halin yanzu (mA). Don auna halin yanzu, dole ne mu kashe wutar lantarki ta jiki kuma mu sanya mita a layi. Mataki na farko yana buƙatar yanki na waya, za mu karya da'ira ta jiki don auna halin yanzu. Cire haɗin wayar VCC zuwa ga resistor, ƙara ɗaya zuwa inda aka haɗa ta, sannan haɗa fil ɗin wutar da ke kan wutar lantarki zuwa resistor. Yana da inganci Yana kashewa iko a cikin kewaye. A mataki na biyu, za mu haɗa multimeter zuwa layi don ya iya auna halin yanzu kamar yadda ya shigo. rafuffuka ta hanyar multimeter zuwa allon da aka buga.

Mataki 2: Duban gani

Idan muka duba kai tsaye, muna buƙatar ɗaukar bayanin kula. Da farko, muna buƙatar bincika idan ECU tana aiki da kyau ko a'a. Dole ne mu duba waje don ganin ko ECU ya tsage ko ya lalace sosai.

Gargadi: Da fatan za a kula da bangarorin biyu, domin ko da karamin tsagewa ko alamun konewa na iya nufin cewa ECU kuskure ne ko kuma ba zai iya aiki ba. Idan akwai lalacewa, za a duba mita don tabbatar da cewa an haɗa shi da ECU kuma an haɗa magungunan gwajin da kyau zuwa tashar jiragen ruwa. Bayan lura da komai, zaku iya fara aunawa tare da multimeter.

Mataki na 3: Fara gwaji da multimeter

Kuna buƙatar gwada kowane bangare tare da multimeter na dijital. Ya kammata ka duba fis da gudu da farko sannan kayi zane na yanzu. Ya kamata a yi gwaji don tabbatar da cewa akwai isasshen wutar lantarki zuwa kwamfutar injin da kuma duba irin ƙarfin lantarki da ke cikin fis da fis. Tabbatar cewa an ba da wutar lantarki zuwa abubuwan haɗin gwiwa lokacin yin gwajin. (1)

Tsarin gwajin ya ƙunshi matakai masu zuwa:

1. Bar halin yanzu akan sikelin A don ma'aunin AC.
2. Baki gwajin kaiwa zuwa COM tashar jiragen ruwa, Jarabawar ja tana kaiwa zuwa mA ohm port.
3. Saita agogon multimeter mai sauyawa akan sikelin A-250mA.
4. Kashe wutar lantarki zuwa da'irar gwaji.
5. Haɗa jajayen binciken a cikin hanyar sandar (+) da kuma binciken baƙar fata a cikin (-) a cikin hanyar na yanzu a cikin gwajin. Haɗa multimeter zuwa da'irar gwaji.
6. Kunna da'irar gwaji.

Waɗannan su ne matakan yin gwajin ECU tare da multimeter. Kula da ma'aunin ma'auni don samun mafi kyawun sakamakon gwaji.

Mataki na 4: Rubuta karatun

Bayan gwajin ECU, za mu ga sakamakon akan allon multimeter. Don multimeter na dijital, sakamakon yana da sauƙin karantawa. Don analog, zan gaya muku matakan don karanta sakamakon auna.

• Ƙayyade ma'auni daidai akan multimeter. Multimeter yana da nuni a bayan gilashin da ke motsawa don nuna sakamakon. Yawancin lokaci ana buga baka uku a bayan allura a baya.

Ana amfani da sikelin Ω don auna juriya kuma yawanci shine mafi girman baka a saman. A kan wannan ma'auni, ƙimar 0 tana hannun dama, ba a hagu ba, kamar yadda yake a kan wasu ma'auni.

- Ma'aunin "DC" yana nuna karatun wutar lantarki na DC.

- Ma'aunin "AC" yana nuna karatun wutar lantarki na AC.

- Ma'aunin "dB" shine mafi ƙarancin amfani. Kuna iya ganin taƙaitaccen bayanin ma'aunin "dB" a ƙarshen wannan sashe.

• Rubuta ma'aunin ma'aunin damuwa. Duba a hankali ga ma'aunin wutar lantarki na DC ko AC. A ƙarƙashin ma'auni za a sami layuka da yawa na lambobi. Bincika kewayon da kuka zaɓa akan alƙalami kuma nemi alamar da ta dace kusa da ɗayan waɗannan layuka. Wannan jerin lambobi ne waɗanda za ku karanta sakamakon.
• Kiyasin farashi. Ma'aunin wutar lantarki akan multimeter na analog yana aiki daidai da ma'aunin ma'aunin matsa lamba na al'ada. An gina ma'aunin juriya akan tsarin logarithmic, wanda ke nufin cewa nisa ɗaya zai nuna canje-canje daban-daban a cikin ƙimar dangane da matsayin da kibiya ke nunawa. (2)

Bayan kammala matakan, za mu sami sakamakon ma'auni. Idan sakamakon auna ya wuce 1.2 amplifiers, EUK yayi kuskure idan sakamakon bai kai ba 1.2 amplifiers, ECU yana aiki kullum.

Lura. Dole ne a kashe wuta koyaushe lokacin yin gwajin ECU don iyakar ingancin gwaji.

Kariya lokacin duba kwamfutar da multimeter

Akwai 'yan abubuwa da ya kamata ku kula yayin da kuke son duba ECU tare da multimeter. Waɗannan matakan kiyayewa zasu tabbatar da amincin ku da amincin sashin sarrafa injin, kuma sune kamar haka:

Gyada

Idan kuna shirin yin amfani da mita don gwada ECU, abu na farko da yakamata ku yi shine sanya safar hannu.

Bincika gani

Yana da matukar mahimmanci a duba sashin kula da injin kuma tabbatar da cewa komai yana cikin tsari.

Duba multimeter

Don samun ingantacciyar gwajin naúrar sarrafa injin ku, tabbatar cewa multimeter ɗinku yana aiki da kyau kuma yana aiki yadda yakamata.

Ƙonewa

Lokacin amfani da multimeter don gwada ECU, tabbatar cewa an kashe maɓallin kunnawa.

ECU haɗin gwiwa

Tare da injin yana gudana, kar a cire haɗin na'urorin sarrafa injin. Yi hankali lokacin haɗa tashar ECU.

Don taƙaita

Al'adar auna ECU tare da multimeter tsari ne mai rikitarwa kuma mai ɗaukar lokaci don novice ko maras gogewa. Wannan labarin zai taimake ka ka magance wannan matsala. Matakan da ke sama sune mafi mahimmancin cikakkun bayanai don kula da su yayin aikin duba ECU tare da multimeter.

Kafin ku tafi, mun jera wasu jagororin gwajin multimeter a ƙasa. Kuna iya duba su ko yi musu alama don karantawa na gaba. Har zuwa karatunmu na gaba!
