Isetshenziswa Kanjani I-Cen-Tech Digital Multimeter ukuze Uhlole I-Voltage

18.02.2023 /

Ungase udinge ukukala i-voltage edlula kusekethe, kodwa awazi ukuthi ungaqala kanjani noma kuphi. Sihlanganise lesi sihloko ukuze sikusize usebenzise i-Cen-Tech DMM ukuhlola ugesi.

Ungasebenzisa i-multimeter yedijithali ukuhlola amandla kagesi ngalezi zinyathelo ezilula nezilula.

  1. Qinisekisa ukuphepha kuqala.
  2. Guqula isikhethi sibe yi-voltage ye-AC noma ye-DC.
  3. Xhuma ama-probe.
  4. Hlola i-voltage.
  5. Thatha ukufunda kwakho.

Izingxenye ze-DMM 

I-multimeter iyithuluzi lokulinganisa imiphumela kagesi eminingana. Lezi zakhiwo zingabandakanya i-voltage, ukumelana, kanye namandla. Isetshenziswa kakhulu ochwepheshe nabalungisa lapho benza umsebenzi wabo.

Ama-multimeter amaningi edijithali anezingxenye ezimbalwa ezibalulekile ukwazi. Ezinye izingxenye zama-multimeters edijithali zihlanganisa okulandelayo.

  • Isikrini se-LCD. Ukufundwa kwe-multimeter kuzoboniswa lapha. Imvamisa kufundwa izinombolo ezimbalwa. Ama-multimeter amaningi namuhla anesikrini esikhanyiselwe emuva ukuze siboniswe kangcono ezimeni ezimnyama nezikhanyayo.
  • Dayela isibambo. Lapha yilapho usetha khona i-multimeter ukuze ulinganise inani elithile noma impahla. Ihlukaniswe izingxenye eziningana ngezinketho eziningi ezihlukahlukene. Lokhu kuzoncika ekutheni ulinganisa ini.
  • AmaJacks. Lezi yizimbobo ezine ezingaphansi kwe-multimeter. Ngokuya ngokuthi ulinganisa ini kanye nohlobo lwesignali yokokufaka oyisebenzisayo njengomthombo, ungabeka izinzwa kunoma iyiphi indawo ekufanele.
  • Ukuphenya. Uxhuma lezi zintambo ezimbili ezimnyama nezibomvu ku-multimeter yakho. Lokhu kokubili kuzokusiza ekulinganiseni izici zikagesi ozenzayo. Bakusiza ukuthi uxhume i-multimeter kusekethe ofuna ukuyikala.

Ama-multimeter ngokuvamile aqoqwa ngokwenani lokufundwayo namadijithi aboniswa esikrinini. Ama-multimeter amaningi akhombisa ukubala okungu-20,000.

Izinto zokubala zisetshenziselwa ukuchaza ukuthi i-multimeter ingenza izilinganiso ngokunembe kangakanani. Laba bangochwepheshe abakhethwa kakhulu njengoba bekwazi ukukala ushintsho oluncane ohlelweni abaxhumeke kulo.

Isibonelo, nge-multimeter yokubala engu-20,000, umuntu angabona ushintsho lwe-1 mV kusiginali ngaphansi kokuhlolwa. I-multimeter ikhethwa ngenxa yezizathu ezimbalwa. Lezi zizathu zihlanganisa okulandelayo:

  • Banikeza ukufundwa okunembile, ukuze uthembele kubo.
  • Ashibhile uma kuqhathaniswa ukuwathenga.
  • Bakala ngaphezu kwengxenye eyodwa kagesi futhi ngaleyo ndlela bayaguquguquka.
  • I-multimeter ilula futhi kulula ukuyithwala isuka endaweni eyodwa iye kwenye.
  • Ama-multimeters angakala ukuphuma okukhulu ngaphandle kokulimala.

Multimeter Basics 

Ukuze usebenzise i-multimeter, kufanele uqale wazi ukuthi iyiphi indawo ofuna ukuyikala.

I-voltage nesilinganiso samanje

Ukuze ulinganise i-voltage ye-AC, vula i-knob yokukhetha ibe ngu-750 esigabeni se-AC.

Ngemuva kwalokho, xhuma umthofu obomvu kusokhethi ephawulwe ukuthi VΩmA kanye nomthofu omnyama kusokhethi ephawulwe ngokuthi COM.. Ungabe usubeka iziphetho zama-lead probe amabili ezintanjeni zesekhethi ozoyihlola.

Ukuze ulinganise amandla kagesi e-DC kusekethe, xhuma umthofu omnyama kokokufaka kwejekhi ebizwa ngokuthi COM, kanye ne-probe enocingo olubomvu kokokufaka kukajeke okubhalwe ukuthi VΩmA.. Vula ukudayela ku-1000 esigabeni se-voltage ye-DC. Ukuze ufunde, beka iziphetho zama-lead probe amabili ezintanjeni zengxenye ngaphansi kokuhlolwa.

Nansi indlela yokukala i-voltage nge-Cen-Tech DMM. Ukulinganisa okwamanje kusekethe nge-multimeter, xhuma umthofu obomvu kusokhethi engu-10ADC kanye nomthofu omnyama kusokhethi ye-COM., Olandelayo, vula inkinobho yokukhetha ibe ama-amps ayi-10. Thinta iziphetho ama-lead probe amabili ezintambo zesekethe ehlolwayo. Rekhoda ukufundwa kwamanje esikrinini sokubonisa.

Kubalulekile ukuqaphela ukuthi ama-multimeter ahlukene angenza ngendlela ehlukile. Sicela ubheke imanuwali yomkhiqizi ukuze ubone ukuthi isebenza kanjani. Lokhu kugwema ukulimala ku-multimeter kanye nokwenzeka kokufundwa okungamanga.

Ukusebenzisa i-Cen-Tech DMM ukuze Uhlole I-Voltage

Ungasebenzisa le multimeter yedijithali ukukala i-voltage edlula kusekethe yengxenye.

Ungakwenza ngezinyathelo ezi-5 ezilula nezilula engizozichaza ngezansi. Lokhu kubandakanya:

  1. Ukuphepha. Ngaphambi kokuxhuma i-DMM kwisekhethi ezokalwa, qiniseka ukuthi iknobhu yokukhetha isendaweni efanele. Lokhu kuzonciphisa ithuba lokulayisha kakhulu ikhawunta. Kufanele futhi uhlole ukuxhumeka kwesekethe kanye nokunikezwa kwamandla ukuze unciphise ukulimala.

Ungaqinisekisa futhi ukuthi isekethe ayiphazanyiswanga muntu futhi isebenza kahle.

Hlola ama-probe amabili okuhola futhi uqiniseke ukuthi awonakele. Ungasebenzisi i-multimeter enama-lead probes awonakele. Zimiselenise kuqala.

  1. Vula iknobhu yesikhethi ukuze ukhethe i-voltage ye-AC noma ye-DC. Kuye ngohlobo lwe-voltage ofuna ukuyilinganisa, uzodinga ukuphendulela i-knob yokukhetha endaweni oyifunayo.
  2. Xhuma ama-probe. Nge-voltage ye-DC, xhuma umthofu obomvu kokokufaka kwe-VΩmA kanye nomthofu omnyama kujack yokufaka evamile (COM). Bese uphendulela inkinobho yokukhetha ibe ngu-1000 engxenyeni ye-DCV. Ngemuva kwalokho, uzokwazi ukukala i-voltage ye-DC kusekethe.

Nge-voltage ye-AC, xhuma umthofu wokuhlola obomvu kujeke wokufaka omakwe i-VΩmA kanye nokuhlola okumnyama kuholele kujeke wokufaka ojwayelekile (COM). I-knob yokukhetha kuyodingeka iguqulelwe ku-750 endaweni ye-ACV.

  1. Hlola i-voltage. Ukuze ulinganise i-voltage, thinta iziphetho zama-probe amabili ezingxenyeni ezisobala zesekethe ehlolwayo.

Uma i-voltage ehlolwayo iphansi kakhulu kusethingi oyikhethile, ungashintsha indawo yeknobhu yokukhetha. Lokhu kuthuthukisa ukunemba kwe-multimeter uma uthatha ukufundwa. Lokhu kuzokusiza ukuthi uthole imiphumela efanele.

  1. Uthatha ukufunda. Ukuze uthole ukufundwa kwe-voltage elinganisiwe, umane ufunde ukufundwa esikrinini sokubonisa esiphezu kwe-multimeter. Konke ukufundwa kwakho kuzovezwa lapha.

Kuma-multimeters amaningi, isikrini sokubonisa siyi-LCD, esihlinzeka ngesibonisi esicacile yingakho singcono futhi kulula ukusisebenzisa. (1)

Izici ze-Cen-Tech Digital Multimeter

Ukusebenza kwe-Cen-Tech DMM akuhlukile kakhulu kulokho kwe-multimeter evamile. Lezi zici zifaka:

  1. Inkinobho yokukhetha. Ungasebenzisa leli sondo ukukhetha umsebenzi oyifunayo kanye nokuzwela okuphelele kwe-multimeter.
  2. Banana Probe Ports. Zitholakala ngaphansi kwe-multimeter ngokuvundlile. Amakwe kusuka phezulu kuya phansi.
  • 10 ACP
  • VOmmA
  • COM
  1. Ipheya lama-lead probes. Lawa ma-probe ashuthekwa kumajekhi amathathu. Umthofu obomvu uvame ukubhekwa njengokuxhumana okuhle kwe-multimeter. I-black lead probe ibhekwa njengokuxhumana okungalungile kumjikelezo we-multimeter.

Kunezinhlobo ezahlukene zama-lead probe ngokuya nge-multimeter oyithengayo. Ahlelwe ngokwezinhlobo zeziphetho anazo. Lokhu kubandakanya:

  • Ubhanana we-tweezers. Ziwusizo uma ufuna ukukala amadivayisi wokukhweza ngaphezulu.
  • Ibamba ubhanana ingwenya. Lezi zinhlobo zama-probe ziwusizo ekulinganiseni izakhiwo zezintambo ezinkulu. Akulungele futhi ukulinganisa izikhonkwane kumabhodi esinkwa. Ziyasebenza ngoba akumele uzibambe zisendaweni ngenkathi uhlola ingxenye ethile.
  • I-Banana hook IC. Asebenza kahle ngamasekethe ahlanganisiwe (ICs). Lokhu kubangelwa ukuthi banamathele kalula emilenzeni yama-circuits ahlanganisiwe.
  • Ubhanana ukuhlola ama-probe. Zingabizi kakhulu ukushintshwa uma ziphukile futhi zingatholakala kuma-multimeters amaningi.
  1. I-fuse yokuvikela. Zivikela i-multimeter kusuka kumanje ngokweqile okungenzeka ukuthi igeleze kuwo. Lokhu kunikeza isivikelo esiyisisekelo. (2)

Ukufingqa

I-Cen-Tech Digital Multimeter iyilokho okudingayo njengamanje ukukala noma iyiphi i-voltage noma yamanje. I-Cen-Tech Digital Multimeter yonga isikhathi futhi ikusiza ukuthi ulinganise ngokushesha ukwehla kwamandla kagesi. Ngithemba ukuthi uzothola lesi sihloko sendlela yokusebenzisa i-Cen-Tech DMM ukuhlola i-voltage iwusizo. Nawu umhlahlandlela omuhle wokuhlola amandla kagesi wentambo ebukhoma.
