Uyivivinya kanjani i-ECU nge-Multimeter (Umhlahlandlela wezinyathelo ezi-4)

Imoto yakho ingaphuka futhi ime ngenxa yezizathu ezihlukahlukene, ukuxilonga lezi zinkinga kubalulekile ukuze uzilungise. Inkinga ingaba yi-ECU. Kodwa kanjani ukuyihlola? 

Ukuze uhlole i-ECU nge-multimeter, udinga ukulandela izinyathelo ezi-4 ezilula: 1. Setha i-multimeter, 2. Yenza ukuhlola okubonakalayo, 3. Xhuma futhi ulandele imihlahlandlela yethu yokuhlola, 4. Rekhoda ukufundwa.

Unamahloni? Ungakhathazeki, ngizokumboza ngemininingwane eyengeziwe ngezansi.

Ungahlola kanjani ikhompyutha nge-multimeter

Nazi izinyathelo ezi-4 ezilula okufanele uzilandele lapho uhlola i-ECU nge-multimeter:

Isinyathelo 1: Setha i-multimeter yakho

I-multimeter iqukethe izingxenye ezi-3 eziyinhloko:

– Isibonisi

- Inkinobho yokukhetha

- Itheku

Firm ukubonisa i-multimeter inezinombolo ezine kanye nekhono lokubonisa uphawu olunegethivu. 

Isibambo sesikhethi ivumela umsebenzisi ukuthi asethe i-multimeter ukuze afunde amanani ahlukahlukene njengamanje (mA), i-voltage (V) kanye nokumelana (Ω). Kufanele sixhume ama-multimeter probes ezimbobeni ezansi kwesibonisi sedivayisi. Kukhona ama-probe amabili, i-probe emnyama kanye ne-probe ebomvu.

Inzwa yombala ixhunywe kuyo Imbobo yeCom (okufushane kokuthi Okujwayelekile), i-probe ebomvu ivamise ukuxhunywa kuyo mA ohm port. Lesi sikhungo singakwazi ukukala ama-currents afika ku-200mA. Lapha u-V umele i-voltage nokumelana no-Ω. Kukhona futhi ichweba 10A, okuyichweba elikhethekile elingakala ngaphezu kuka-200mA.

izinyathelo zokuqala

Okulandelayo, setha i-multimeter ukukala amandla amanje (mA). Ukuze ukwazi ukukala okwamanje, kufanele sivale ngokoqobo umsinga futhi sibeke imitha emgqeni. Isinyathelo sokuqala sidinga ucezu locingo, sizokwephula ngokomzimba isifunda ukukala okwamanje. Nqamula intambo ye-VCC eya ku-resistor, engeza eyodwa lapho ixhumeke khona, bese uxhuma iphinikhodi kumthombo wamandla kusiphikisa. Iyasebenza Iyavala amandla kusekethe. Esinyathelweni sesibili, sizoxhuma i-multimeter kulayini ukuze ikwazi ukukala okwamanje njengoba ingena. imifudlana ngokusebenzisa i-multimeter kuya ebhodini lesifunda eliphrintiwe.

Isinyathelo sesi-2: Ukuhlola Okubonakalayo

Lapho sibheka ngokuqondile, sidinga ukubhala amanothi. Okokuqala, sidinga ukuhlola ukuthi i-ECU isebenza kahle noma cha. Kufanele sibheke ngaphandle ukuze sibone ukuthi i-ECU iphukile noma yonakele kakhulu.

Isexwayiso: Sicela ubeke iso kuzo zombili izinhlangothi, ngoba ngisho nokuqhekeka okuncane noma izimpawu zokusha kungase kusho ukuthi i-ECU inephutha noma ayisebenzi. Uma kwenzeka umonakalo, imitha izobhekwa ukuze kuqinisekiswe ukuthi ixhunywe ku-ECU nokuthi imikhondo yokuhlola ixhumeke kahle echwebeni. Ngemuva kokubona konke, ungaqala ukulinganisa nge-multimeter.

Isinyathelo sesi-3: Qala ukuhlola nge-multimeter

Udinga ukuhlola ingxenye ngayinye nge-multimeter yedijithali. Kumele hlola i-fuse bese udlulisela kuqala bese wenza umdwebo wamanje. Kufanele kwenziwe ukuhlolwa ukuze kuqinisekiswe ukuthi kunamandla anele okuya kukhompyutha yenjini futhi kubhekwe ugesi ohamba ngenzwa namafuse. Qiniseka ukuthi amandla anikezwa ezingxenyeni lapho wenza ukuhlolwa. (1)

Inqubo yokuhlola ihlanganisa lezi zinyathelo ezilandelayo:

1. Shiya yamanje esikalini esingu-A ukuze uthole ukulinganisa kwe-AC.
2. Black test kuholela Imbobo ye-COM, ukuhlolwa okubomvu kuholela ku mA ohm port.
3. Setha ukushintsha kwewashi le-multimeter esikalini A-250mA.
4. Vala amandla esekethe yokuhlola.
5. Xhuma i-probe ebomvu ohlangothini lwesigxobo esingu-(+) kanye ne-probe emnyama ngendlela engu-(-) lapho kuya khona lapho ohlolwayo. Xhuma i-multimeter kumjikelezo wokuhlola.
6. Vula isifunda sokuhlola.

Lezi yizinyathelo zokwenza ukuhlolwa kwe-ECU nge-multimeter. Naka isikali senkomba ukuze uthole imiphumela yokuhlolwa engcono kakhulu.

Isinyathelo sesi-4: Bhala phansi okufundiwe

Ngemuva kokuhlolwa kwe-ECU, sizobona imiphumela esikrinini se-multimeter. Ukuze uthole i-multimeter yedijithali, umphumela kulula ukuwufunda. Nge-analog, ngizokutshela izinyathelo zokufunda imiphumela yokulinganisa.

• Nquma isikali esilungile ku-multimeter. I-multimeter ine-pointer ngemuva kwengilazi ehambayo ukukhombisa umphumela. Ngokuvamile ama-arcs amathathu aphrintwa ngemuva kwenaliti ngemuva.

Isikali sika-Ω sisetshenziselwa ukukala ukumelana futhi ngokuvamile siyi-arc enkulu kunazo zonke phezulu. Kulesi sikali, inani elingu-0 lingakwesokudla, hhayi kwesokunxele, njengoba linjalo kwezinye izikali.

- Isikali se-"DC" sibonisa ukufundwa kwamandla kagesi e-DC.

- Isikali "AC" sibonisa ukufundwa kwamandla kagesi we-AC.

- Isikali "dB" sisetshenziswa kancane. Ungabona incazelo emfushane yesilinganiso se-"dB" ekupheleni kwalesi sigaba.

• Bhala inkomba yesikali sokucindezeleka. Bheka eduze isikali sikagesi se-DC noma se-AC. Ngaphansi kwesikali kuzoba nemigqa eminingana yezinombolo. Hlola ububanzi obukhethile esibayeni bese ubheka uphawu oluhambisana nalo eduze komunye wale migqa. Lolu uchungechunge lwezinombolo ozofunda kulo umphumela.
• Izindleko ezilinganiselwe. Isikali se-voltage ku-multimeter ye-analog sisebenza ngokufanayo ne-gauge evamile yokucindezela. Isilinganiso sokumelana sakhiwe ohlelweni lwe-logarithmic, okusho ukuthi ibanga elifanayo lizobonisa izinguquko ezihlukene zevelu kuye ngendawo umcibisholo okhomba kuyo. (2)

Ngemva kokuqeda izinyathelo, sizothola umphumela wokulinganisa. Uma umphumela wokulinganisa udlula Ama-amplifiers angama-1.2, i-EUK inephutha uma umphumela ungaphansi Ama-amplifiers angama-1.2, i-ECU isebenza ngokujwayelekile.

Qaphela. Ukuthungela kufanele kucishwe njalo lapho kwenziwa ukuhlolwa kwe-ECU ukuze uthole ukuphumelela kokuhlolwa okuphezulu.

Izinyathelo zokuqapha lapho uhlola ikhompyutha nge-multimeter

Kunezinto ezimbalwa okufanele uziqaphele lapho ufuna ukuhlola i-ECU nge-multimeter. Lezi zinyathelo zokuphepha zizoqinisekisa kokubili ukuphepha kwakho nokuphepha kweyunithi yokulawula injini, futhi imi kanje:

Amagundane

Uma uhlela ukusebenzisa imitha ukuhlola i-ECU, into yokuqala okufanele uyenze ukugqoka amagilavu.

Hlola ngokubuka

Kubaluleke kakhulu ukuhlola iyunithi yokulawula injini futhi uqiniseke ukuthi konke kuhamba ngohlelo.

Hlola i-multimeter

Ukuze uthole ukuhlolwa okunembile kweyunithi yakho yokulawula injini, qiniseka ukuthi i-multimeter yakho isebenza kahle futhi inikwe amandla ngendlela efanele.

Ukuthungela

Uma usebenzisa i-multimeter ukuhlola i-ECU, qiniseka ukuthi ukhiye wokuthungela uvaliwe.

Ukuxhumana kwe-ECU

Uma injini isebenza, ungawanqamuli amayunithi okulawula injini. Qaphela lapho uxhuma itheminali ye-ECU.

Ukufingqa

Umkhuba wokulinganisa i-ECU nge-multimeter iyinqubo eyinkimbinkimbi futhi edla isikhathi ku-novice noma ongenalwazi. Lesi sihloko sizokusiza ukuxazulula le nkinga. Izinyathelo ezingenhla ziyimininingwane ebaluleke kakhulu okufanele uyinake ngesikhathi sokuhlola i-ECU nge-multimeter.

Ngaphambi kokuthi uhambe, sibale imihlahlandlela embalwa yokuhlola ye-multimeter ngezansi. Ungawahlola noma uwabeke uphawu ukuze uwafunde kamuva. Kuze kube isifundo sethu esilandelayo!

• Ungahlola kanjani imodyuli yokulawula ukuthungela nge-multimeter
• Ungazifunda Kanjani Ukufundwa Kwe-Analog Multimeter
