Kuyini multimeters digital

Omunye jikelele esikoleni Yiqiniso physics ayaziwa ukuthi wesifunda ngogesi kwenzeka libhekene eziningi nemingcele. Phakathi kwabo, ukubaluleka voltage, eyaziwa nangokuthi i-ezingaba ukubaluleka kanye nohlobo lamanje egeleza ngokusebenzisa umqhubi, amandla sokudliwa umthwalo kusukela kunethiwekhi, ukubaluleka ukumelana (e Ohms) kanye nabanye. Ukulinganisa ngalinye kulawa amadivayisi ezikhethekile zidaliwe. Ngenxa yalesi ammeters zamanje, voltage -. Voltmeters, ohmmeters zokumelana, njll Nokho, kuthiwani uma kunesidingo ukukala ezingaphezu kweyodwa ipharamitha, kodwa eziningana? Gqoka wonke amadivayisi ekhona nge? Kulokhu, ingasaphathwa eyabantu ukuhamba kanye lula. izixazululo jikelele adaliwe ukuxazulula le nkinga: amadivayisi ezisebenza ngokuhlanganisa kwabanye eziningana. Ngokwesibonelo, ukushintshela ku endaweni yokuqala inkinobho ekhethekile, ungakwazi ukukala voltage, okwesibili isebenze logic yangaphakathi, okuvumela ukuba sithole ukumelana. Kalula! Amadivayisi anjalo zaziwa ngokuthi multimeters. Lokho "multi" - eningi, kahle, "amamitha" - ngesilinganiso. Eyesibili isihloko, engesiyo ngempela lesifanele, - abahloli. multimeters Modern digital ukuvumela ukukala sebuningini imingcele kusukela elula ingxenye ukumelana wesifunda lokushisa kuma.

ukulungiswa

Naphezu kokuhlukahluka enkulu yalezi amadivaysi, bahlukene ngezigaba ezimbili eziyinhloko: analog multimeters digital. Kubasebenzisi abaningi Nokho kukhona kuwusizo kakhudlwana Elesibili, nakuba owokuqala kunezinzuzo eziningana, ethize.

Esikalini iziqu umcibisholo

Analog imodeli cishe out of umkhiqizo, njengoba isidingo kubo lalilincane, kuqhathaniswa okunye (Digital multimeter DT manje adume). Nokho, emakethe Kusengenzeka ukuhlangabezana, izixazululo ezintsha efanayo, ngakho halamuzi kubo. amadivaysi Analog okulula kakhulu ukuhlukanisa kwabanye emzimbeni kuyinto inkinobho ratchet yokukhetha imodi wokulinganisa, kanye ibha kahle esikhulu nge esikalini lapho uphawu division (efana umugqa). Uma uxhuma probe yamanje wesifunda kwenzeka ohlobo kwangaphakathi, kazibuthe ikhiqizwa kanye nokuxhumana yabo kubangela Umcibisholo lokhombisa baphambukile engela ezithile. It kuphela uhlala ukubala intengo ukwahlukana futhi zifunde ukubaluleka kokuphila ipharamitha elinganisiwe. multimeters Digital kulesi sici akukhetha kakhulu kusukela iphutha ayifakiwe ukuhunyushwa isikali esingaphezu kwesinqunywe ngezansi embukisweni ratchet mkhawulo.

Bonisa izinombolo

Digital Multimeters bheka cishe iyafana analog, ngaphandle ukuthi block pointer esikhundleni isikrini compact, okuyinto ubonisa imiphumela nesilinganiso. izinguquko Yangaphakathi Yiqiniso, kuyinto ephawuleka kakhulu. On onyathelisiwe wesifunda ibhodi ibekwe chip eyenza kuqedile isiginali engenayo esuka ukuba kwenziwe uphenyo. Ngokuvamile, izakhi eziningana ezengeziwe asetshenziswa - resistors, capacitors nocingo. Phakathi izici ehlukile zalezi zinqumo, kuyafaneleka ingane iphutha yokukala - okusezingeni eliphezulu ekilasini ukunemba, sibangela ngisho isabelomali onobuhle, isibonelo, ezifana 838 multimeter digital.

Efingqa

Ukuze umuntu ngezinye izikhathi kunesidingo ukukala ezinye kwemigomo wesifunda ekhaya noma, isibonelo, imoto isimiso sikagesi, zamanani aphansi umhloli digital kuyisinqumo esingcono kakhulu. Ubufakazi obanelisayo ukuqonda imithetho zisebenzisa ratchet futhi baqonde isimiso sokukhetha ububanzi nesilinganiso.
