Uhlolojikelele lophawu lokumelana namamitha amaningi

Kungenzeka ukuthi ujwayelene ne-multimeter. Cishe ukubonile lokhu eduze kochwepheshe noma yimuphi omunye uchwepheshe. Nami nganginjalo, ngaze ngaba nesidingo hhayi nje sokuyifunda kuphela, kodwa nokufunda ukuyisebenzisa ngendlela efanele.

Kunzima kangakanani ukuthi ugesi ugeleze ngento ethile, uma kunzima kakhulu, khona-ke kukhona ukumelana okuphezulu. 

I-multimeter yinto engasetshenziswa ukukala ukumelana, ithumela ugesi omncane ngokusebenzisa isekethe. Njengoba nje kukhona amayunithi ubude, isisindo, kanye nebanga; Iyunithi yokulinganisa yokumelana ku-multimeter yi-ohm.

Uphawu luka-ohm ngu-Ω (olubizwa ngokuthi i-omega, uhlamvu lwesiGreki). (1)

Uhlu lwezimpawu zokulinganisa ukumelana lumi kanje:

  • Om = Om.
  • kOhm = kOhm.
  • Umama = megaohm.

Kulesi sihloko, sizobheka ukumelana nokulinganisa nge-multimeter yedijithali ne-analog.

Ukulinganisa ukumelana ne-multimeter yedijithali 

Izinyathelo okufanele zilandelwe ukuqedela inqubo yokuhlola ukumelana

  1. Wonke amandla esekethe evivinywayo kufanele acime.
  2. Qinisekisa ukuthi ingxenye engaphansi kokuhlolwa ihlukaniswe nayo yonke isekethe.
  3. Isikhethi kufanele sibe ku-Ω.
  1. Umthofu wokuhlola nama-probe kufanele kuxhunywe kahle kumatheminali. Lokhu kuyadingeka ukuze uthole umphumela onembile.
  2. Buka iwindi ukuze uthole ukufundwa kwe-Ω.
  3. Khetha ububanzi obufanele, obusuka ku-1 ohm ukuya ku-megaohm (isigidi).
  4. Qhathanisa imiphumela nencazelo yomkhiqizi. Uma ukufundwa kufanelana, ukumelana ngeke kube yinkinga, noma kunjalo, uma ingxenye ingumthwalo, ukumelana kufanele kube ngaphakathi kokucaciswa komkhiqizi.
  5. Uma ukulayishwa ngokweqile (OL) noma i-infinity (I) kubonisiwe, ingxenye ivuliwe.
  6. Uma kungekho okunye ukuhlola okudingekayo, imitha kufanele "icishwe" futhi igcinwe endaweni ephephile.

Ukulinganisa ukumelana ne-analog multimeter

  1. Khetha i-elementi ofuna ukukala ukumelana kwayo.
  2. Faka ama-probe esokhethini elifanele bese uhlola imibala noma izimpawu.
  3. Thola ububanzi - lokhu kwenziwa ngokubheka ukushintshashintsha komcibisholo esikalini.
  1. Thatha isilinganiso - lokhu kwenziwa ngokuthinta iziphetho eziphambene zengxenye ngayo yomibili imikhondo.
  2. Funda imiphumela. Uma ububanzi busethelwe ku-100 ohms futhi inaliti ima ku-5, umphumela uba ama-ohms angu-50, okuphindwe ka-5 kwesikali esikhethiwe.
  3. Setha i-voltage ebangeni eliphezulu ukuze uvimbele umonakalo.

Ukufingqa

Ukulinganisa ukumelana ne-multimeter, kungakhathaliseki ukuthi idijithali noma i-analog, kudinga ukunakwa ukuze uthole umphumela onembile. Ngiqinisekile ukuthi lesi sihloko sikusiza ukuthi ufunde ukuthi yini okufanele uyenze uma usebenzisa i-multimeter ukukala ukumelana. Kungani ubandakanya uchwepheshe ukuze uthole isheke elilula uma ukwazi! (2)
