Maitiro ekuyedza ECU ine Multimeter (Matanho mana-Nhanho)

Mota yako inogona kudonha uye kumira nekuda kwezvikonzero zvakasiyana, kuongorora matambudziko aya kwakakosha kuti ugadzirise. Dambudziko rinogona kunge riri ECU. Asi sei kuzviongorora? 

Kuti uedze ECU ne multimeter, unoda kutevera 4 matanho ari nyore: 1. Gadzira multimeter, 2. Itai kuongorora kwekuona, 3. Batanidza uye tevera mazano edu ekuedza, 4. Rekodha kuverenga.

Kunyara? Usanetseka, ini ndichavhara izvi zvakadzama pazasi.

Maitiro ekutarisa komputa ine multimeter

Heano matanho mana akareruka ekutevera kana uchitarisa ECU ine multimeter:

Danho 1: Gadzira yako multimeter

Iyo multimeter ine zvikamu zvitatu zvikuru:

– Ratidza

-Sarudzo knob

- Chiteshi

The company kuratidza multimeter ine manhamba mana uye kugona kuratidza chiratidzo chisina kunaka. 

Selector mubato inobvumira mushandisi kumisikidza iyo multimeter kuverenga akasiyana siyana akadai seazvino (mA), voltage (V) uye kuramba (Ω). Isu tinofanirwa kubaya maviri multimeter probes mumachiteshi pazasi pekuratidzira kwechishandiso. Pane maprobe maviri, probe nhema uye dzvuku probe.

Iyo sensor yemavara yakabatana nayo Com port (pfupi yeCommon), iyo dzvuku probe inowanzobatanidzwa kune mA ohm port. Chiteshi ichi chinogona kuyera mafambiro anosvika 200 mA. Pano V inomirira voltage uye kuramba Ω. Kune zvakare chiteshi 10A, inova chiteshi chakakosha chinogona kuyera kupfuura 200mA.

kutanga matanho

Tevere, gadzira iyo multimeter kuyera simba razvino (mA). Kukwanisa kuyera ikozvino, isu tinofanirwa kudzima ikozvino uye kuisa mita mumutsara. Danho rekutanga rinoda chidimbu chewaya, isu tichapwanya dunhu kuyera ikozvino. Bvisa waya yeVCC ichienda kune chinopikisa, wedzera imwe kwayakabatanidzwa, wozobatanidza pini yemagetsi pane magetsi kune resistor. Inoshanda Inodzima simba mudunhu. Muchikamu chechipiri, tichabatanidza multimeter kumutsara kuitira kuti ikwanise kuyera ikozvino sezvainopinda. hova kuburikidza ne multimeter kune yakadhindwa redunhu bhodhi.

Danho rechitatu: Kuongorora Kwekuona

Patinotarisa zvakananga, tinofanira kutora manotsi. Kutanga, tinofanira kutarisa kana ECU iri kushanda zvakanaka kana kwete. Isu tinofanirwa kutarisa kunze kuti tione kana ECU yakatsemuka kana kukuvadzwa zvakanyanya.

Yambiro: Ndapota ramba wakatarisa kumativi ose maviri, nokuti kunyange kutsemuka kuduku kana zviratidzo zvekupisa zvinogona kureva kuti ECU yakashata kana kuti haigoneki. Muchiitiko chekukuvara, mita inotariswa kuti ive nechokwadi chekuti yakabatana neECU uye kuti bvunzo dzinotungamira dzakanyatsobatana nechiteshi. Mushure mekutarisa zvese, unogona kutanga kuyera ne multimeter.

Danho rechitatu: Tanga kuedza ne multimeter

Iwe unofanirwa kuyedza chimwe nechimwe chikamu nedhijitari multimeter. Unofanira tarisa fuse uye relay kutanga wobva waita dhirowa iripo. Muedzo unofanirwa kuitwa kuti uve nechokwadi chekuti kune simba rakakwana rinoenda kune komputa yeinjini uye kutarisa voltage inopinda nesensor nemafusi. Ita shuwa kuti simba rinopihwa kune zvikamu pakuita bvunzo. (1)

Iyo yekuyedza maitiro inosanganisira anotevera matanho:

1. Siya iripo pachiyero cheA chechiyero che AC.
2. Black test inotungamirira ku COM port, muedzo mutsvuku unotungamirira ku mA ohm port.
3. Isa iyo multimeter wachi ichichinja pachiyero A-250mA.
4. Dzima simba kune test circuit.
5. Batanidza probe dzvuku munzira ye (+) danda uye dema probe munzira ye (-) mugwara rezvino muchiyedzo. Batanidza iyo multimeter kune test circuit.
6. Batidza test circuit.

Aya ndiwo matanho ekuita ECU bvunzo ine multimeter. Chenjerera kune zvikero zve index kuti uwane mhinduro dzakanakisa dzebvunzo.

Danho rechina: Nyora pasi kuverenga

Mushure meiyo ECU bvunzo, isu tichaona mhinduro pane multimeter skrini. Kune digital multimeter, mhedzisiro yacho iri nyore kuverenga. Kune analog, ini ndichakuudza matanho ekuverenga zviyero zvekuyera.

• Sarudza chiyero chakakodzera pane multimeter. Iyo multimeter ine pointer kuseri kwegirazi inofamba kuratidza mhedzisiro. Kazhinji matatu arcs anodhindwa kuseri kwetsono kumashure.

Iyo Ω chiyero chinoshandiswa kuyera kuramba uye kazhinji ndiyo hombe arc kumusoro. Pachiyero ichi, kukosha 0 kuri kurudyi, kwete kuruboshwe, sezvazviri pane mamwe mashekeri.

-Chiyero che "DC" chinoratidza iyo DC voltage kuverenga.

-Chikero che "AC" chinoratidza kuverenga kwe AC voltage.

-Chiyero che "dB" ndicho chishoma kushandiswa. Iwe unogona kuona tsananguro pfupi ye "dB" chiyero pakupera kwechikamu chino.

• Nyora stress scale index. Tarisa zvakanyanya paDC kana AC voltage scale. Pasi pechiyero pachava nemitsara yakawanda yenhamba. Tarisa huwandu hwawakasarudza pachinyoreso uye tsvaga chiratidzo chinoenderana neimwe yemitsara iyi. Iyi nhevedzano yenhamba kubva kwauchaverenga mhedzisiro.
• Inofungidzirwa mutengo. Iyo voltage chiyero pane analog multimeter inoshanda zvakafanana kune yakajairwa kumanikidza geji. Chiyero chekupikisa chinovakwa pane logarithmic system, zvinoreva kuti chinhambwe chimwechete chicharatidza shanduko dzakasiyana mukukosha zvichienderana nenzvimbo inonongedzwa nemuseve. (2)

Mushure mekupedza nhanho, tinozogamuchira mugumisiro wekuyera. Kana chiyero chekuyera chichipfuura 1.2 amplifiers, EUK ine mhosva kana mhedzisiro iri shoma pane 1.2 amplifiers, ECU iri kushanda zvakajairika.

Cherechedza. Kubatidza kunofanirwa kugara kuchidzimwa paunenge uchiita bvunzo dzeECU kuti unyatso bvunzo.

Chengetedzo kana uchitarisa komputa ine multimeter

Pane zvinhu zvishoma zvaunofanira kutarisa kana iwe uchida kutarisa ECU ine multimeter. Aya ekuchenjerera anovimbisa kuchengetedzeka kwako uye kuchengetedzeka kweinjini yekudzora unit, uye ndeaya anotevera:

Glove

Kana uri kuronga kushandisa mita kuyedza ECU, chinhu chekutanga chaunofanira kuita kupfeka magirovhosi.

Ongorora nemaziso

Zvinonyanya kukosha kuongorora injini yekudzora unit uye kuve nechokwadi chekuti zvese zviri muhurongwa hwekushanda.

Tarisa multimeter

Kuti uwane bvunzo chaiyo yeinjini yako yekudzora unit, ita shuwa kuti multimeter yako iri kushanda nemazvo uye ine simba nemazvo.

Galvanzie

Paunenge uchishandisa multimeter kuyedza ECU, ita shuwa kuti kiyi yekudzima yakadzimwa.

ECU kubatana

Neinjini iri kushanda, usabvisa mayunitsi ekudzora injini. Ngwarira paunenge uchibatanidza ECU terminal.

Summing up

Muitiro wekuyera ECU ne multimeter inzira yakaoma uye inopedza nguva kune mutsva kana asina ruzivo. Ichi chinyorwa chichakubatsira kugadzirisa dambudziko iri. Matanho ari pamusoro apa ndiwo akanyanya kukosha ruzivo rwekuteerera panguva yekudzidzira kutarisa ECU ine multimeter.

Usati waenda, isu takanyora mashoma multimeter bvunzo madhairekitori pazasi. Unogona kuzvitarisa kana kuisa bookmark kuti uverenge gare gare. Kusvikira chidzidzo chedu chinotevera!
