Multimeter resistance chizindikiro mwachidule

19.02.2023 /

Mutha kudziwa zambiri za multimeter. Mwinamwake mwawonapo izi pafupi ndi akatswiri kapena katswiri wina aliyense. Ndinalinso choncho, mpaka ndinafunika osati kungophunzira, komanso kuphunzira kugwiritsa ntchito moyenera.

Ndizovuta bwanji kuti magetsi azidutsa mu chinachake, ngati chiri chovuta kwambiri, ndiye kuti pali kukana kwakukulu. 

Multimeter ndi chinthu chomwe chingagwiritsidwe ntchito kuyeza kukana, chimatumiza magetsi ang'onoang'ono kudzera mudera. Monga momwe pali zigawo zautali, kulemera, ndi mtunda; Chigawo cha muyeso wa kukana mu multimeter ndi ohm.

Chizindikiro cha ohm ndi Ω (chotchedwa omega, chilembo cha Chigriki). (1)

Mndandanda wa zizindikiro zoyezera kukana ndi motere:

  • Om = Om.
  • kOm = kOm.
  • MAMA = megaohm.

M'nkhaniyi, tiwona kuyeza kukana ndi multimeter ya digito ndi analogi.

Kuyeza kukana ndi multimeter ya digito 

Zoyenera kutsatira kuti mutsirize ndondomeko yoyesera kukana

  1. Mphamvu zonse za dera lomwe zikuyesedwa ziyenera kuzimitsidwa.
  2. Onetsetsani kuti gawo lomwe likuyesedwa likusiyanitsidwa ndi dera lonse.
  3. Chosankhacho chiyenera kukhala pa Ω.
  1. Mayeso otsogolera ndi ma probe ayenera kulumikizidwa bwino ndi ma terminals. Izi ndizofunikira kuti mupeze zotsatira zolondola.
  2. Yang'anani pawindo kuti muwerenge Ω.
  3. Sankhani mtundu wolondola, womwe umachokera ku 1 ohm mpaka megaohm (miliyoni).
  4. Yerekezerani zotsatira ndi ndondomeko ya wopanga. Ngati zowerengerazo zikugwirizana, kukana sikudzakhala vuto, komabe, ngati chigawocho ndi cholemetsa, kukana kuyenera kukhala mkati mwa zomwe wopanga amapanga.
  5. Pamene overload (OL) kapena infinity (I) akuwonetsedwa, chigawocho chimatsegulidwa.
  6. Ngati palibe kuyezetsa kwina, mita iyenera "kuzimitsidwa" ndikusungidwa pamalo otetezeka.

Kuyeza kukana ndi analogi multimeter

  1. Sankhani chinthu chomwe mukufuna kuyeza kukana kwake.
  2. Ikani ma probes mu socket yoyenera ndikuwona mitundu kapena zolembera.
  3. Pezani mtundu - izi zimachitika powona kusinthasintha kwa muvi pa sikelo.
  1. Yesani muyeso - izi zimachitika pogwira malekezero a chigawocho ndi zitsogozo zonse ziwiri.
  2. Werengani zotsatira. Ngati mtunduwo wakhazikitsidwa ku 100 ohms ndipo singano imayima pa 5, zotsatira zake ndi 50 ohms, zomwe ndi 5 kuwirikiza sikelo yosankhidwa.
  3. Khazikitsani voteji pamlingo wapamwamba kuti mupewe kuwonongeka.

Kufotokozera mwachidule

Kuyeza kukana ndi multimeter, kaya digito kapena analogi, kumafuna chidwi kuti mupeze zotsatira zolondola. Ndikukhulupirira kuti nkhaniyi yakuthandizani kuti mudziwe zoyenera kuchita mukamagwiritsa ntchito multimeter kuyeza kukana. Bwanji kuphatikizira katswiri kuti afufuze mosavuta ngati mungathe! (2)

Onani zina mwazolemba zathu pansipa.

  • Momwe mungayesere ma amps ndi multimeter
  • Momwe mungayesere spark plug ndi multimeter
  • Momwe mungayesere wowononga dera ndi multimeter
