Ungasetha kanjani isilungiselelo sokuqhubeka se-multimeter
Okuqukethwe
I-multimeter yedijithali ingenye yamathuluzi awusizo kakhulu ongawasebenzisa ukuxazulula izinkinga zikagesi. Ukusetha okuqhubekayo ku-multimeter kukuvumela ukuthi uhlole ukuthi kukhona yini indlela kagesi ephelele phakathi kwamaphoyinti amabili.
Iyini isethingi yokuqhubeka ye-multimeter?
Isethingi yokuqhubeka ye-multimeter isetshenziselwa ukuhlola ukuthi isekethe ivuliwe noma imfushane. Isethingi yokuqhubeka ye-multimeter izobonisa uma kunesekhethi egcwele nalapho kungekho isifunda esigcwele. (1)
Uma usebenzisa isethingi yokuqhubeka ye-multimeter, ufuna impendulo ezwakalayo. Uma kungekho ukuxhumana okuqhubekayo phakathi kwemikhondo yokuhlola, ngeke uzwe inkomba ezwakalayo. Lapho imikhondo yokuhlola ithintana, uzozwa ibhiphu.
Luyini uphawu lokuqhubeka ku-multimeter?
Uphawu lokuqhubeka ku-multimeter umugqa odayagonali onomcibisholo ekugcineni ngakunye. Kubukeka kanje: → ←
Ungahlola okuningi lapha ukuze uthole uphawu lokuqhubeka kwe-multimeter.
Kuyini ukufunda okuhle kokuqhubeka?
Uma uhlola ukuqhubeka nge-multimeter, ufuna ukufundwa okubonisa ukumelana phakathi kuka-0 no-20 ohms (ohms). Lolu hlu lukhombisa ukuthi kunendlela egcwele ugesi ongahamba ngayo. Ngezinye izikhathi lapho uhlola ukuqhubeka kwezintambo ezinde noma izintambo, ungase ubone ukufundwa kokumelana okuphakeme okusaqhubeka. Lokhu kungase kubangelwe umsindo ocingweni.
Ungahlola kanjani ukuqhubeka kwesekethe ngaphandle kwe-multimeter?
Ukuhlola ukuqhubeka nakho kungenziwa ngebhethri nesibani esifakiwe. Ngomthofu webhethri owodwa ohlangothini olulodwa lwebulb ethintayo, xhuma enye ingxenye yebhethri kumthofu owodwa wedivaysi ehlolwayo (DUT). Thinta enye intambo ye-DUT uye kolunye uhlangothi lwesibani. Uma kukhona ukuqhubeka, isibani sizovutha.
Zisho ukuthini izilungiselelo ze-multimeter?
Ama-multimeters anezilungiselelo ezimbalwa ezingasetshenziswa ukukala i-voltage, yamanje, nokumelana. Isilungiselelo sokuqhubeka siwusizo ekuhloleni ukuqhubeka kwesekhethi, noma kubalulekile ngoba sikuvumela ukuthi uhlole ukuthi ikhona yini indlela yokuthi ugesi uhambe phakathi kwamaphoyinti amabili.
Imibuzo evame ukubuzwa
Uyini umehluko phakathi kokuqhubeka nokumelana?
I-multimeter ekuqhubekeni ikala ukumelana. Ukumelana phakathi kwamaphuzu amabili kungu-zero uma kungekho ukumelana (isifunda sivaliwe), futhi okungapheli uma kungekho uxhumano (isifunda siphukile). Kumamitha amaningi, umkhawulo wesignali yomsindo ucishe ube ngu-30 ohms.
Ngakho-ke, i-multimeter iyakhala uma kukhona isifunda esifushane noma lapho umkhondo uthintana ngokuqondile. Izophinda futhi ikhala uma umkhondo wokuhlola uhlangana nentambo yokumelana ephansi kakhulu phansi (isibonelo, lapho uxhuma umthofu wokuhlola ocingweni lwaphansi esokhethini).
Ingabe kufanele kube khona ukuqhubeka phakathi kwezigaba?
Cha. Ukuhlola kanjani ukuqhubeka? Qiniseka ukuthi awukho ngephutha ibanga le-amplifier. Uma uhlola ukuqhubeka ngendlela efanele futhi uthola ukufundwa, lapho-ke unenkinga.
Kuyini ukuqhubeka okubi?
Umqhubi ngamunye unokumelana okuthile ekudlulisweni kwamandla kagesi. Ama-conductor aphansi afanelekile ngoba avumela ukwanda kwamanje ngaphandle kokushisa okukhulu. Uma ukumelana kwe-resistor phakathi kwamatheminali ayo kudlula i-10-20 ohms (Ω), khona-ke kungase kube nesici futhi kufanele kushintshwe. (2)
Ingabe wonke ama-multimeters ahlola ukuqhubeka?
Akuwona wonke ama-multimeters anezilungiselelo zokuqhubeka, kodwa ngokuvamile anezinye izilungiselelo ezingasetshenziswa ukuhlola umjikelezo ovuliwe. Ungasebenzisa ukulungiselelwa kokumelana kwe-multimeter noma ukulungiselelwa kwayo kwe-diode ukuze uthole amasekhethi avuliwe.
Yini engasetshenziswa ukuhlola ukuqhubeka?
Isilungiselelo sokuqhubeka ku-multimeter sihlola ukumelana phakathi kwamaphoyinti amabili kusekethe kagesi. Uma ukumelana kungu-zero, isifunda sivaliwe futhi idivayisi izokhala. Uma isifunda singavaliwe, uphondo ngeke lukhale.
Kwenzekani uma ucingo lunokuqhubeka?
Uma kukhona ukuqhubeka, kusho ukuthi akukho ukuphuka ocingweni futhi ugesi ungageleza kuwo ngokujwayelekile.
Ukulandelana - kuhle noma kubi?
Ukuqhubeka kuhle. Ukuqhubeka kusho ukuthi kunendlela ephelele yokuhamba kukagesi. Uma ufaka i-multimeter yakho kumodi eqhubekayo, ubona ukuthi ugesi ungadlula yini entweni oyihlolayo. Uma kungenzeka, khona-ke unokuqhubeka futhi i-multimeter yakho izokhala noma ibonise inombolo esikrinini sayo (kuye ngokuthi hlobo luni lwe-multimeter onalo). Uma ungezwa ibhiphu noma ukubona inombolo, akukho ukuqhubeka futhi ugesi awukwazi ukugeleza ocezwini lwesisetshenziswa.
