Indlela yokunquma ukuthi iyiphi ucingo olushisayo ngaphandle kwe-multimeter (izindlela ezi-4)

Okuqukethwe

Indlela yoku-1: sebenzisa i-proximity detector
Indlela yesi-2: Sebenzisa i-screwdriver yomhloli
Indlela yesi-3: sebenzisa isibani njengesihloli
- Indlela yokwenza umtshina we-bulb
- Kusetshenziswa isibani ukukhomba intambo ephilayo
Indlela yesi-4: Ukusebenzisa Amakhodi Ombala

Kulesi sihloko, ngizokukhombisa ukuthi ungayibona kanjani intambo eshisayo noma ephilayo ngaphandle kokusebenzisa i-multimeter.

I-multimeter ikuvumela ukuthi uhlole i-polarity yezintambo; Nokho, uma ungenayo, zikhona ezinye izindlela zokwenza okufanayo. Njengochwepheshe kagesi othenjwayo, ngifunde amathiphu namacebo ambalwa phakathi neminyaka yokukhomba ikhebula elibukhoma ngaphandle kokusebenzisa i-multimeter, engingakufundisa yona. Ezinye izindlela zingakusiza ngoba i-multimeter ingase ibize kakhulu emsebenzini wakho wesikhathi esisodwa.

Ngokuvamile, uma ungenayo i-multimeter, ungasebenzisa:

Umtshina wamandla kagesi
Thinta i-screwdriver
Xhuma isibani ocingweni
Sebenzisa ikhodi yombala ejwayelekile

Ngizohlanganisa ngayinye ngemininingwane eyengeziwe ngezansi.

Indlela yoku-1: sebenzisa i-proximity detector

Ngiyaqonda ukuthi lesi sinyathelo singase singatholakali uma ungakwazi ukufinyelela noma yimaphi amathuluzi osebenza ngogesi, lapho ke ngingaphakamisa ukuthi uqhubekele kokuthathu okulandelayo.

Landela lezi zinyathelo ezilula ukuze uthole ukuthi ucingo luyashisa yini usebenzisa umtshina we-voltage ongathinteki.

Isinyathelo 1. Gcina i-proximity detector iseduze nento noma ukuhlola.

Isinyathelo 2. Isibonisi kumtshina sizokhanyisa.

Isinyathelo 3. Umtshina we-voltage ongathinteki uzokhala uma kukhona i-voltage entweni noma ocingweni.

Isinyathelo 4. Uhlola ukuthi i-current egeleza ocingweni ibalulekile.

Amathiphu: Ungawubambi umtshina kagesi ngamaprobe, izintambo nanoma iyiphi enye ingxenye yesihloli ngesikhathi sokuhlolwa. Lokhu kungase kulimaze umhloli futhi kukwenze kungaphephile ukusebenzisa.

Izithonjana eziningi zisebenza ngokuyenga inkambu kazibuthe eshintshanayo entweni ehlolwayo. Uma into inikwe amandla, inkambu kazibuthe edaliwe izobangela ukuthi ugesi ugeleze. Isekhethi yomtshina izobe isibona i-current and beep.

Nokho, qiniseka ukuthi umtshina we-voltage ongathinteki uyasebenza ngaphambi kokusetshenziswa. Lokhu kubaluleke kakhulu ngoba imiphumela edukisayo ingaholela ekulimaleni okukhulu nezingozi.

Indlela yesi-2: Sebenzisa i-screwdriver yomhloli

Enye indlela yokunquma ukuthi intambo iyashisa noma ibukhoma ukusebenzisa isikrudrayiva sokuhlola.

I-oda

Isinyathelo 1: veza izintambo

Ungakwazi ukuvula ikhava noma ususe noma yini eyenza izintambo zingafinyeleleki.

Mhlawumbe ufuna ukuhlola izintambo ngemuva kweswitch; kulesi simo, qaqa ikhava yokushintsha ukuze ufinyelele izintambo ofuna ukuhlola i-polarity.

Isinyathelo sesi-2: Thola iphoyinti eliveziwe ocingweni

Ngenxa yokuthi izintambo eziningi zivalekile, udinga indawo ekahle nengenalutho ukuze uthinte isikrudrayiva somhloli.

Uma ungakwazi ukuthola indawo engenalutho ocingweni lapho ungabeka khona i-screwdriver yomhloli, ngincoma ukuthi ukhumule ucingo. Kodwa okokuqala, kufanele uvale amandla edivayisini osebenza nayo kuphaneli yokushintsha. Ungazihlungi izintambo ezibukhoma ngaphandle kokuhlangenwe nakho okufanele. Ungase ubanjwe ugesi.

Landela lezi zinyathelo:

Thola i-wire stripper noma i-pliers insulated.
Khipha izintambo ofuna ukuhlola i-polarity
Faka cishe uhhafu we-intshi yocingo emihlathini ye-stripper yocingo noma ipliers futhi unqamule okokufaka.
Manje usungakwazi ukubuyisela amandla futhi uqhubeke nokuhlola.

Isinyathelo sesi-3: Thinta i-screwdriver yomhloli ezintanjeni ezingenalutho.

Ngaphambi kokuqhubeka nokuhlola kwangempela, qiniseka ukuthi i-screwdriver yomhloli wakho ivalwe ngokwanele ukuze ugweme izingozi.

Ngemuva kwalokho, bamba ingxenye ehlanganisiwe bese uthinta izingxenye ezingenalutho noma ezihlutshiwe zezintambo. Qiniseka ukuthi isikrudrayiva somhloli sithintana kahle nezintambo.

Ngokuhambisanayo, hlola isibani se-neon ku-screwdriver, uma uthinta ucingo olushisayo (nge-screwdriver tester), isibani se-neon sizokhanya. Uma ucingo lungenawo amandla (umhlabathi noma ukungathathi hlangothi), isibani se-neon ngeke sikhanyise. (1)

Ukunakwa: I-screwdriver yesihloli esinesici singanikeza imiphumela engalungile. Ngakho-ke, qiniseka ukuthi i-screwdriver yakho iyasebenza. Uma kungenjalo, ungase ube nesekhethi emfushane.

Indlela yesi-3: sebenzisa isibani njengesihloli

Okokuqala, udinga ukwenza lo mtshina ube lula ukuwusebenzisa. Ungabese uyisebenzisela ukuhlola intambo eshisayo.

Indlela yokwenza umtshina we-bulb

Isinyathelo 1. Sicela uqaphele ukuthi isibani kufanele sixhunywe ekugcineni kwentambo. Ngakho, isibani kufanele sibe nentamo exhunywe ocingweni.

Isinyathelo 2. Xhuma enye ingxenye yocingo kupulaki ukuze ifakwe kusokhethi.

Ukunakwa: akuyona inkinga uma uxhuma intambo emnyama, ebomvu noma yimuphi omunye ku-bulb; ukukhanya komhloli kufanele kuthinte ucingo olushisayo futhi kukhanyise - yile ndlela obona ngayo ucingo olushisayo.

Kusetshenziswa isibani ukukhomba intambo ephilayo

Isinyathelo 1. Nquma umhlabathi - oluhlaza noma ophuzi.

Isinyathelo 2. Thatha isihloli bese uxhuma isiphetho esisodwa kukhebuli yokuqala futhi enye kuntambo yaphansi. Uma ukukhanya kuvela, kuyintambo eshisayo (ikhebula lokuqala). Uma kungenjalo, kungaba intambo engathathi hlangothi.

Isinyathelo 3. Hlola enye intambo bese ubheka indlela isibani sokukhanyisa esisebenza ngayo.

Isinyathelo 4. Qaphela intambo ebukhoma - leyo ekhanyise isibani. Lena intambo yakho ebukhoma.

Indlela yesi-4: Ukusebenzisa Amakhodi Ombala

Lena mhlawumbe indlela elula yokukhomba ikhebula eliphilayo noma elishisayo ezintweni ezisebenza ngogesi noma izintambo zokuhlanganisa; nokho, akuzona zonke izinto zikagesi ezinamakhodi afanayo ezintambo. Ngaphezu kwalokho, amakhodi ezintambo ayahluka ngezwe nesifunda. Okulandelayo indinganiso yombala wendawo yokuhlala yezintambo zikagesi.

Ezintweni eziningi zokukhanyisa zasendlini, ikhodi yocingo imi kanje (Ikhodi Kagesi Kazwelonke yase-US)

izintambo ezimnyama - izintambo zinamandla noma zinamandla.
Izintambo eziluhlaza noma ezingenalutho - khetha izintambo eziphansi kanye nokuxhumana.
izintambo eziphuzi – futhi imele ukuxhumana komhlabathi
izintambo ezimhlophe - amakhebuli angathathi hlangothi.

Leli zinga lombala lisungulwa Ikhodi Kagesi Kazwelonke futhi inakekelwa yi-National Fire Protection Association. (2)

Kodwa-ke, ngenxa yokuhluka kwamazinga emibala kwezinye izifunda, awukwazi ukuthembela ngokuphelele kumakhodi ombala ukuze uhlonze intambo ebukhoma. Futhi, ungazithinti izintambo uze wazi ukuthi yiziphi. Ngale ndlela, uzonciphisa amathuba ezingozi.
