Indlela yokuhlola inzwa yokushisa nge-multimeter

Amageji anephutha noma izinzwa zokushisa zivamise ukunikeza imiphumela engelona iqiniso uma zisetshenziswa, okuholela ohambweni olubizayo oluya kumakhenikha nokulungiswa okungadingekile, ngakho ukuxazulula inkinga kubalulekile. Udinga inzwa egcwele yezinga lokushisa enokunemba kwesigaba sokuqala.

Igeji yezinga lokushisa noma igeji isiza ukugcina izinga lokushisa elingashintshi ukuze injini isebenze kahle.

Ukukuqondisa ezinyathelweni zokuhlola isimo se-thermometer yakho, ngichaze izindlela ezine ezinemininingwane zokuqinisekisa ukuthi i-thermometer yakho isebenza kahle.

Ngokuvamile, ukuhlola nokuxazulula izinkinga izinzwa zokushisa kuhlanganisa:

1. Izintambo zokuhlola kanye nendawo evamile

2. Ukuhlola isignali ye-Ohm kusukela Kudivayisi Yokudlulisa

3. Ukuhlola isignali ye-ohm kugeji yokucindezela futhi ekugcineni

Ihlola i-pressure gauge ngokwayo

Kulo mhlahlandlela, sizodlula lezi zinyathelo ezingenhla ngokuningiliziwe.

Uzodinga amathuluzi alandelayo:

• I-multimeter yedijithali
• Izintambo ezixhumayo
• Umthombo wamandla (1)
• inzwa yokushisa
• Isibali, ipeni nephepha
• Iyunithi yomthumeli
• Umshini

Uyixazulula Kanjani Inzwa Yezinga lokushisa Eyehlulekile noma Engaphandle Evamile

Landela lezi zinyathelo ukuze uhlole ukusebenza kwe-thermometer yakho:

1. Izintambo zokuhlola kanye nendawo evamile. Uma izintambo zingaxhumekile kahle, noma uma ziphukile futhi zinqanyuliwe, inzwa yezinga lokushisa ngeke isebenze kahle noma imise ukusebenza. Ukuze uhlole indawo evamile yocingo, bamba umkhondo owodwa wokuhlola kuntambo yaphansi bese uxhuma omunye umthofu wokuhlola esigxotsheni sikagesi esinentambo (umhlabathi) ukuze wenze i-multimeter isebenze njenge-ammeter. Izobonisa amanani ahlukahlukene esikrinini. Inani kufanele libe nguziro ocingweni olusekelwe phansi, ngaphandle kwalokho iphutha lenzeka.
2. Ihlola isignali ye-ohm evela kumthumeli. Izikhathi eziningi uye wazithola usesimweni lapho udinga ukufaka esikhundleni seyunithi yomthumeli wegeji yezinga lokushisa emotweni yakho. Ukuze uhlole ububanzi be-ohm, udinga ukuxhuma igeji ku-multimeter yakho, uqiniseke ukuthi uxhuma amatheminali avumayo ngendlela efanele (okungukuthi, positive kuya kokuphozithivu nokunegethivu kuya kokunegethivu). Qiniseka ukuthi uthola ukufundwa kwezinzwa ezindaweni ezingenalutho nezigcwele ukuze ukwazi ukukhetha ukuhlanganiswa kwenzwa okulungile kwemoto yakho. Ngemva kokuxhuma isidluliseli ku-DMM esimisweni se-ohm (ungakhetha ama-ohm angu-2000 - ungakwazi ukuklwebha amatheminali esidluliseli ukuze uthole ukufundwa okunembe kakhudlwana), bhala inani lokumelana noma ububanzi. Ukwazi ububanzi bokumelana kwenzwa yakho kuzokusiza ukuthi ukhethe inzwa ehambisanayo yemoto yakho.
3. Ungahlola kanjani isignali ye-ohm kugeji yokucindezela. Ukuze ulinganise ukumelana, okubuye kwaziwe ngokuthi ukumelana ne-gauge, qiniseka ukuthi akukho okwamanje okugeleza kubhokisi lomthumeli nanoma iyiphi enye ingxenye ongathanda ukuyihlola, bese ufaka amapulagi/amapulagi amnyama nabomvu ku-COM naku-omega VΩ ngokulandelana, shintsha i-multimeter. kumodi yokumelana enelebuli engu-Ω bese usetha ububanzi bufike phezulu. Xhuma ama-probe kusidlulisi noma idivayisi ofuna ukuyihlola (unganaki i-polarity njengoba ukumelana kungenasiqondiso), lungisa ububanzi kugeji futhi uthole inani le-OL, elivame ukuba ngu-1OL.
4. Ekugcineni, hlola inzwa. Ungakwenza lokhu ngokwenza okulandelayo:

• Nqamula igeji yezinga lokushisa kusuka kuyunithi yokuthumela.
• Shintshela ukhiye (ukuthungela) endaweni "yokuvula".
• Xhuma intambo yenzwa yezinga lokushisa kumotho usebenzisa ama-jumpers.
• Qinisekisa ukuthi ukufundwa kwegeji lokushisa kuphakathi kokubanda nokushisayo
• Shintshela ukhiye endaweni ebhalwe ukuthi "Valiwe."
• Bheka ama-fuse aqhunyiswe emotweni nalawo axhunywe kwinzwa yokushisa, bese uwashintsha uma eshaywa.
• Gcoba ucingo (i-jumper) enamathiselwe kutheminali yenzwa eduze kwenjini.
• Bese uvula ukhiye wokuthungela ngaphandle kokuvula imoto. Kuleli qophelo, uma inzwa yokushisa ibonisa "kushisa", kusho ukuthi kukhona ucingo oluphukile kudivayisi yokudlulisa futhi kufanele ulungise inzwa yokushisa.

Ukufingqa

Ngethemba ukuthi lesi sifundo sikusize ngakho-ke akumele uye kumakhenikha izikhathi eziningi ukuze uhlole noma ulungise inzwa. Ungakwenza ngokwakho futhi unciphise izindleko zemoto yakho. (2)
