Uyihlola Kanjani Indawo Nge-Multimeter (Izinyathelo Eziyisi-6)

Kunoma yiluphi uhlelo lwezintambo zikagesi, ukuba khona kocingo oluphansi kubalulekile. Ngezinye izikhathi ukungabikho kocingo oluphansi kungaholela emiphumeleni eyinhlekelele kuwo wonke umjikelezo. Yingakho namuhla sizobheka indlela yokuhlola umhlabathi nge-multimeter.

Njengomthetho, ngemuva kokusetha i-multimeter ku-voltage ephezulu, ungafaka izinkomba zokuhlola ukuze uhlole izintambo ezishisayo, ezingathathi hlangothi neziphansi kanye nama-voltages azo. Khona-ke ungakwazi ukunquma ukuthi i-outlet isekelwe kahle noma cha. Ngezansi sizocubungula lokhu.

Yini i-grounding?

Ngaphambi kokuthi siqale inqubo yokuhlola, sidinga ukuxoxa ngesisekelo. Ngaphandle kokuqonda okufanele kwesisekelo, ukuya phambili akusho lutho. Ngakho nansi incazelo elula yokubeka phansi.

Inhloso eyinhloko yokuxhumanisa ugesi ukudlulisa ugesi olahliwe usuka entweni esetshenziswayo noma esitolo ukuya phansi. Ngakho-ke, akekho ozothola ukushaqeka kukagesi ngenxa yokukhishwa kukagesi. Iphrothokholi efanele yokuphepha enendawo yokusebenza idinga intambo. Ungasebenzisa le nqubo ekhaya lakho noma emotweni. (1)

6 Isinyathelo somhlahlandlela wokuhlola i-Ground wire nge-Multimeter

Kulesi sigaba, sizoxoxa ngendlela yokuhlola umhlabathi nge-multimeter. Futhi, kule demo, sizosebenzisa indawo kagesi yasendlini evamile. Umgomo uwukuthola ukuthi i-outlet isekelwe kahle yini. (2)

Isinyathelo sesi-1 - Setha i-multimeter yakho

Okokuqala, kufanele usethe kahle i-multimeter yenqubo yokuhlola. Ngakho-ke, setha i-multimeter yakho kumodi ye-voltage ye-AC. Kodwa-ke, uma usebenzisa i-analog multimeter, kufanele usethe ukudayela ku-V isikhundla.

Ngakolunye uhlangothi, uma usebenzisa i-DMM, kufanele ujikeleze izilungiselelo uze uthole i-voltage ye-AC. Uma usuyitholile, setha inani le-cutoff libe ku-voltage ephezulu kakhulu. Khumbula, ukusetha i-voltage endaweni ephakeme kakhulu kuzokusiza kakhulu ekutholeni ukufundwa okunembile.

Kodwa-ke, amanye ama-multimeters athunyelwa ngaphandle kwamanani anqunyiwe. Kulokhu, setha i-multimeter kuzilungiselelo ze-voltage ye-AC bese uqala ukuhlola.

Isinyathelo sesi-2 - Xhuma izinzwa

I-multimeter inama-probe amabili emibala ehlukene, obomvu nomnyama. Lawa ma-probe amabili kufanele axhunywe ngokufanelekile kuma-multimeter's port. Ngakho-ke, xhuma isivivinyo esibomvu embobeni ephawulwe ngokuthi V, Ω, noma +. Bese uxhuma i-probe emnyama embobeni enelebuli - noma COM. Ukuxhumeka okungalungile kwalawa ma-probe amabili nezimbobo kungase kubangele umjikelezo omfushane ku-multimeter.

Futhi, ungasebenzisi izinzwa ezilimele noma eziqhekekile. Futhi, gwema ukusebenzisa ama-probe anezintambo ezingenalutho ngoba ungase uthole ukushaqeka kukagesi ngesikhathi sokuhlolwa.

Isinyathelo sesi-3 - Hlola Ukufunda Usebenzisa Izimbobo Ezisebenzayo Nemaphakathi

Manje ungabheka intambo yaphansi nge-multimeter. Kuleli qophelo, kufanele uhlole izintambo ezishisayo nezingathathi hlangothi ngemikhondo yokuhlola ye-multimeter.

Ngaphambi kokwenza lokhu, qiniseka ukuthi ubamba ama-probes avela kuma-insulating wraps, lokhu kuzokuvikela kunoma yimiphi imithelela.

Bese ufaka i-probe ebomvu embobeni esebenzayo.

Thatha i-probe emnyama futhi uyifake embobeni engathathi hlangothi. Ngokuvamile, imbobo encane iyimbobo esebenzayo futhi imbobo enkulu iyimbobo emaphakathi.

“Kodwa-ke, uma ungakwazi ukuhlonza amachweba, ungahlala usebenzisa indlela evamile. Khipha izintambo ezintathu, bese ngemibala ehlukene, ungakwazi ukuqonda kalula izintambo.

Ngokuvamile intambo ephilayo iba nsundu, intambo emaphakathi iba luhlaza okwesibhakabhaka, futhi intambo yaphansi iba phuzi noma eluhlaza.”

Ngemva kokufaka ama-probe amabili ngaphakathi kwezimbobo ezibukhoma nezimaphakathi, hlola i-voltage ku-multimeter bese uyirekhoda.

Isinyathelo sesi-4 - Hlola i-voltage usebenzisa imbobo engaphansi

Manje kufanele uhlole i-voltage phakathi kwezimbobo ezibukhoma nomhlabathi. Ukuze wenze lokhu, susa umthofu wokuhlola obomvu embobeni engathathi hlangothi bese uwufaka ngokucophelela embobeni yaphansi. Unganqamuli i-probe emnyama embobeni esebenzayo phakathi nale nqubo. Imbobo ephansi iyimbobo eyindilinga noma emise okwe-U etholakala ngezansi noma ngaphezulu kwendawo yokuphuma.

Hlola ukufundwa kwe-voltage ku-multimeter bese uyibhala phansi. Manje qhathanisa lokhu kufunda nokufundwe kwangaphambilini.

Uma uxhumano lwe-outlet lusekelwe phansi, uzothola ukufundwa okungaphakathi noma ku-5V. Kodwa-ke, uma ukufundwa phakathi kwembobo ebukhoma nomhlaba kunguziro noma eduze noziro, lokho kusho ukuthi i-outlet ayisekelwe phansi.

Isinyathelo sesi-5 - Qhathanisa Konke Ukufundwa

Udinga okungenani ukufundwa okuthathu ukuze uthole ukuqhathanisa okufanele. Usuvele unokufundwa okubili.

Ukufunda kuqala: Ukufunda ichweba elibukhoma nelingathathi hlangothi

Ukufunda okwesibili: Itheku lesikhathi sangempela nokufunda phansi

Manje thatha ukufundwa okuvela embobeni engathathi hlangothi kanye nembobo ephansi. Kwenze:

1. Faka uphenyo olubomvu embobeni engathathi hlangothi.
2. Faka i-probe emnyama embobeni yaphansi.
3. Bhala phansi okufundiwe.

Uzothola inani elincane kulawa machweba amabili. Kodwa-ke, uma uxhumano lwendlu lungagxiliwe, asikho isidingo sokufunda okwesithathu.

Isinyathelo sesi-6 - Bala ukuvuza okuphelele

Uma uqedele izinyathelo 3,4, 5, XNUMX kanye no-XNUMX, manje unokufundwa okuthathu okuhlukene. Kulokhu kufundwa okuthathu, bala ukuvuza okuphelele.

Ukuze uthole ukuvuza okuphelele, susa ukufunda kokuqala kwesibili. Bese wengeza ukufundwa kwesithathu ekufundweni okuwumphumela. Uma umphumela wokugcina umkhulu kuno-2V, kungenzeka ukuthi usebenza ngentambo yaphansi enephutha. Uma umphumela ungaphansi kuka-2V, isokhethi iphephile ukusetshenziswa.

Lena indlela enhle yokuthola izintambo zaphansi ezingalungile.

Izinkinga zokumisa ugesi wezimoto

Kunoma iyiphi imoto, kungase kube nezinkinga ezithile zikagesi ngenxa yokungaqini kahle phansi. Ngaphezu kwalokho, lezi zinkinga zingabonakala ngezindlela eziningi, ezinjengomsindo kusistimu yomsindo, izinkinga ngepompo likaphethiloli, noma ukungasebenzi kahle kokulawulwa kwenjini kagesi. Uma ungakwazi ukugwema lezi zinkinga, kuyoba kuhle kuwe kanye nemoto yakho.

Nawa amanye amathiphu okuthi ungasivikela kanjani isimo esinjalo.

Iphuzu lekhwalithi ephansi

Iningi lethu licabanga ukuthi uma ucingo oluphansi luhlangana nemoto, yonke into iba phansi. Kodwa lokhu akulona iqiniso. Intambo yaphansi kufanele ixhunywe kahle emotweni. Isibonelo, khetha iphuzu elingenalo upende nokugqwala. Bese uxhuma.

Sebenzisa i-multimeter ukuhlola umhlabathi

Ngemva kokuxhuma ucingo oluphansi, kuhlale kungcono kakhulu ukuhlola umhlabathi. Ngakho-ke, sebenzisa i-multimeter kule nqubo. Sebenzisa ibhethri nentambo yaphansi ukuze unqume amandla kagesi.

Sebenzisa izintambo ezinkulu

Kuye ngamandla amanje, kungase kudingeke ushintshe usayizi wentambo yaphansi. Ngokuvamile, izintambo ezenziwe efekthri zingu-10 kuya ku-12 gauge.

Ngezansi kukhona eminye imihlahlandlela yokuqeqeshwa kwe-multimeter ongayihlola.

• Ungayisebenzisa kanjani i-multimeter ukuhlola i-voltage yezintambo ezibukhoma
• Indlela yokunquma intambo engathathi hlangothi nge-multimeter
• Isetshenziswa Kanjani I-Cen-Tech Digital Multimeter ukuze Uhlole I-Voltage
