Momwe Mungayesere ECU ndi Multimeter (4-Step Guide)

Galimoto yanu imatha kuwonongeka ndikuyima pazifukwa zosiyanasiyana, kuzindikira mavutowa ndikofunikira kuti muwakonze. Vuto likhoza kukhala ECU. Koma bwanji fufuzani izo? 

Kuti muyese ECU ndi multimeter, muyenera kutsatira njira 4 zosavuta: 1. Konzani multimeter, 2. Chitani zowonetseratu, 3. Lumikizani ndikutsatira ndondomeko zathu zoyesera, 4. Lembani zowerengera.

Kuchita manyazi? Osadandaula, ndifotokoza mwatsatanetsatane pansipa.

Momwe mungayang'anire kompyuta ndi multimeter

Nawa masitepe anayi osavuta kutsatira mukamayang'ana ECU ndi ma multimeter:

Khwerero 1: Konzani ma multimeter anu

Multimeter ili ndi magawo atatu:

- Chiwonetsero

- Chosankha chosankha

- Padoko

Kampaniyo chiwonetsero multimeter ili ndi manambala anayi ndikutha kuwonetsa chizindikiro choyipa. 

Chogwirizira chosankha imalola wogwiritsa ntchito kukhazikitsa ma multimeter kuti awerenge zinthu zosiyanasiyana monga zapano (mA), voliyumu (V) ndi kukana (Ω). Tiyenera kulumikiza ma probe awiri a multimeter m'madoko pansi pa chiwonetsero cha chipangizocho. Pali zofufuza ziwiri, kafukufuku wakuda ndi kafukufuku wofiira.

Sensa yamtundu imalumikizidwa ndi Com port (chidule cha Common), kafukufuku wofiyira nthawi zambiri amalumikizidwa ndi mA ohm doko. Doko ili limatha kuyeza mafunde mpaka 200mA. Apa V akuyimira voteji ndi kukana Ω. Palinso pa 10A, lomwe ndi doko lapadera lomwe limatha kuyeza kuposa 200mA.

njira yoyamba

Kenako, khazikitsani multimeter kuti muyese mphamvu yomwe ilipo (mA). Kuti athe kuyeza panopa, tiyenera kuzimitsa panopa ndi kuika mita mu mzere. Gawo loyamba limafuna chidutswa cha waya, tidzathyola dera kuti tiyeze zomwe zikuchitika. Lumikizani waya wa VCC kupita ku chopinga, onjezani imodzi pomwe idalumikizidwe, kenako lumikizani pini yamagetsi pamagetsi ndi chopinga. Ndizothandiza Zimazimitsa mphamvu mu dera. Mu sitepe yachiwiri, tidzagwirizanitsa multimeter ku mzere kuti athe kuyeza panopa pamene ikulowa. mitsinje kudzera mu multimeter kupita ku bolodi losindikizidwa.

Gawo 2: Kuyang'ana Zowoneka

Tikayang'ana mwachindunji, tiyenera kulemba manotsi. Choyamba, tiyenera kufufuza ngati ECU ikugwira ntchito bwino kapena ayi. Tiyenera kuyang'ana kunja kuti tiwone ngati ECU yasweka kapena yawonongeka kwambiri.

Chenjezo: Chonde yang'anani mbali zonse ziwiri, chifukwa ngakhale mng'alu wochepa kapena zizindikiro zoyaka moto zingatanthauze kuti ECU ndi yolakwika kapena yosagwira ntchito. Pakawonongeka, mita idzayang'aniridwa kuti iwonetsetse kuti ikugwirizana ndi ECU komanso kuti mayendedwe oyesera akugwirizana bwino ndi doko. Pambuyo poyang'ana zonse, mukhoza kuyamba kuyeza ndi multimeter.

Khwerero 3: Yambani kuyesa ndi multimeter

Muyenera kuyesa gawo lililonse ndi multimeter ya digito. Muyenera yang'anani fuyusi ndikutumiza koyamba ndiyeno konzani zojambulazo. Kuyezetsa kuyenera kuchitidwa kuti muwonetsetse kuti pali mphamvu zokwanira zopita ku kompyuta ya injini ndikuyang'ana voteji yomwe imadutsa mu sensa ndi fuse. Onetsetsani kuti mphamvu imaperekedwa ku zigawo zikuluzikulu poyesa. (1)

Njira yoyesera ili ndi izi:

1. Siyani yapano pa sikelo ya A kuti muyezedwe ndi AC.
2. Mayeso akuda amatsogolera ku Chithunzi cha COM, mayeso ofiira amatsogolera ku mA ohm doko.
3. Khazikitsani wotchi ya multimeter pa sikelo A-250mA.
4. Zimitsani mphamvu ku dera loyesa.
5. Lumikizani kafukufuku wofiyira molunjika kwa (+) pole ndi kafukufuku wakuda molunjika ku (-) komwe kuli pano pakuyesa. Lumikizani multimeter ku dera loyesa.
6. Yatsani dera loyesa.

Awa ndi masitepe opangira mayeso a ECU ndi ma multimeter. Samalani masikelo a index kuti mupeze zotsatira zabwino kwambiri za mayeso.

Gawo 4: Lembani zomwe zawerengedwa

Pambuyo pa mayeso a ECU, tiwona zotsatira pazithunzi za multimeter. Kwa multimeter ya digito, zotsatira zake ndi zosavuta kuwerenga. Kwa analogi, ndikuuzani masitepe kuti muwerenge zotsatira zoyezera.

• Dziwani sikelo yoyenera pa multimeter. Multimeter ili ndi cholozera kumbuyo kwa galasi chomwe chimayenda kuwonetsa zotsatira. Kawirikawiri ma arcs atatu amasindikizidwa kumbuyo kwa singano kumbuyo.

Sikelo ya Ω imagwiritsidwa ntchito kuyeza kukana ndipo nthawi zambiri imakhala arc yayikulu kwambiri pamwamba. Pa sikelo iyi, mtengo 0 uli kumanja, osati kumanzere, monga momwe zilili pamiyeso ina.

- Sikelo ya "DC" ikuwonetsa kuwerenga kwamagetsi a DC.

- Sikelo ya "AC" ikuwonetsa kuwerenga kwamagetsi a AC.

- Sikelo ya "dB" ndiyosagwiritsidwa ntchito kwambiri. Mutha kuwona kufotokozera mwachidule za sikelo ya "dB" kumapeto kwa gawoli.

• Lembani stress scale index. Yang'anani mozama pa sikelo yamagetsi ya DC kapena AC. Pansi pa sikelo padzakhala mizere ingapo ya manambala. Yang'anani mndandanda womwe mwasankha pa cholembera ndikuyang'ana chizindikiro chofananira pafupi ndi umodzi mwa mizere iyi. Izi ndi mndandanda wa manambala omwe mudzawerenge zotsatira.
• Mtengo woyerekeza. Mphamvu yamagetsi pa multimeter ya analogi imagwira ntchito mofananamo ndi geji yodziwika bwino. Mlingo wotsutsa umamangidwa pa dongosolo la logarithmic, zomwe zikutanthauza kuti mtunda womwewo udzawonetsa kusintha kosiyana kwa mtengo kutengera malo omwe muvi umalozera. (2)

Mukamaliza masitepe, tidzalandira zotsatira zoyezera. Ngati muyeso uposa 1.2 amplifiers, EUK ndi yolakwika ngati zotsatira zake ndi zochepa kuposa 1.2 amplifiers, ECU ikugwira ntchito bwino.

Zindikirani. Kuyatsa kuyenera kuzimitsidwa nthawi zonse poyesa mayeso a ECU kuti muyese bwino kwambiri.

Chenjezo poyang'ana kompyuta ndi multimeter

Pali zinthu zingapo zomwe muyenera kusamala mukafuna kuyang'ana ECU ndi multimeter. Izi zitsimikizira chitetezo chanu komanso chitetezo cha gawo lowongolera injini, ndipo ndi motere:

Magulu

Ngati mukukonzekera kugwiritsa ntchito mita kuyesa ECU, chinthu choyamba muyenera kuchita ndi kuvala magolovesi.

Onani mowonekera

Ndikofunikira kwambiri kuyang'ana gawo lowongolera injini ndikuwonetsetsa kuti zonse zikuyenda bwino.

Onani ma multimeter

Kuti mupeze mayeso olondola a injini yanu yoyang'anira, onetsetsani kuti multimeter yanu ikugwira ntchito bwino komanso yoyendetsedwa bwino.

Poyatsira

Mukamagwiritsa ntchito multimeter kuyesa ECU, onetsetsani kuti kiyi yoyatsira yazimitsidwa.

Kugwirizana kwa ECU

Ndi injini ikugwira ntchito, musagwirizane ndi mayunitsi owongolera injini. Samalani mukalumikiza malo a ECU.

Kufotokozera mwachidule

Mchitidwe woyezera ECU ndi multimeter ndizovuta komanso zowononga nthawi kwa novice kapena osadziwa. Nkhaniyi ikuthandizani kuthetsa vutoli. Masitepe omwe ali pamwambawa ndi mfundo zofunika kwambiri zomwe muyenera kuziganizira mukamayesa kufufuza ECU ndi multimeter.

Musanapite, talembapo maupangiri angapo oyesa ma multimeter pansipa. Mutha kuziwona kapena kuziyika chizindikiro kuti muwerenge mtsogolo. Mpaka phunziro lathu lotsatira!

• Momwe mungayesere gawo lowongolera poyatsira ndi multimeter
• Momwe Mungawerengere Kuwerenga kwa Analogi Multimeter
• Momwe mungayesere capacitor ndi multimeter
