Kodi ma voltage negative amatanthauza chiyani pa multimeter?

19.02.2023 /

Multimeter imayeza ma voltage, apano komanso kukana. Monga lamulo, kuwerenga kwa ma multimeter ndikwabwino kapena koyipa, ndipo muyenera kumvetsetsa bwino zamagetsi kuti muyese kuwerenga. Kuwerenga koyipa komanso kolimbikitsa kwa ma multimeter, kumatanthauza chiyani?

Kuwerengera koyipa kwamagetsi pa multimeter kumatanthauza kuti pakali pano pali ma elekitironi ochulukirapo. Zikatero, chinthucho chimalandira malipiro oipa.

Zomwe muyenera kuyang'ana voteji pa multimeter?

Nazi zonse zomwe mungafune kuti muwone mphamvu yamagetsi pa multimeter yanu:

  • Complete multimeter
  • Gwero la magetsi osasokoneza
  • Kudziwa bwino zamagetsi ndi sayansi kuti mumvetsetse zowerengera

Kodi ndingayeze bwanji voteji ndi multimeter?

Voltage ndi imodzi mwamagawo omwe amatha kuyeza ndi ma multimeter. Pakadali pano, ma multimeter onse a analogi ndi digito atha kupezeka pamsika. Mu bukhuli, tiwona njira yowonjezereka yoyezera voteji ndi multimeter, yomwe ili yoyenera komanso yogwiritsidwa ntchito pa ma analogi ndi digito multimeters.

Gawo 1 - Kodi mukuyezera ma voltage? Ngati ndi choncho, ndi magetsi a DC kapena AC? Ngati mukuyeza magetsi m'nyumba mwanu, mwina ndi AC, koma ngati ndi galimoto kapena chipangizo choyendetsedwa ndi batri, ndiye kuti mwina ndi DC.

Gawo 2 - Sinthani chosinthira chosankha kukhala voteji yoyenera yomwe mukufuna kuyeza. Mphamvu yamagetsi ya AC imaimiridwa ndi sine wave. Kwa DC, ndi mzere wowongoka wokhala ndi madontho pansi pake.

Gawo 3 - Pezani zotulutsa za COM pa multimeter yanu ndikulumikiza chiwongolero chakuda.

Gawo 4 - Pezani cholumikizira cholembedwa V ndikulumikiza cholumikizira chofiyira.

Gawo 5 - Pa mtundu wolondola wa voteji, ikani chosinthira chosankha kuti chikhale chamtengo wapatali.

Gawo 6 - Yatsani chipangizo, galimoto, kapena chipangizo chamagetsi chomwe mukufuna kuyeza.

Gawo 7 - Onetsetsani kuti kafukufuku wakuda ndi kafukufuku wofiyira akukhudza mathero awiri a chinthu chomwe mukuyezera magetsi.

Gawo 8 - Kuwerenga kwanu kwamagetsi tsopano kuwonekera pazithunzi za multimeter.

Momwe mungawerenge ndikumvetsetsa kuwerengera kwamagetsi?

Pali mitundu iwiri yokha ya ma voliyumu omwe adzawonetsedwa pa multimeter: kuwerengera kwabwino komanso koyipa.

Musanadumphire muzowerengera, kumbukirani kuti mu multimeter iliyonse, zofiira zimasonyeza zabwino ndi zakuda zimasonyeza zoipa. Izi zimagwiranso ntchito ku masensa ndi zizindikiro zina ndi mawaya.

Mtengo wolakwika umatanthauza kuti dera lomwe likugwiritsidwa ntchito silili lokhazikika. Ali ndi nyonga. Mtengo wamagetsi olakwika umachitika chifukwa cha kuchuluka kwa ma elekitironi. Kuwerenga kolimbikitsa ndikosiyana kwenikweni ndi izi. Multimeter idzawonetsa phindu labwino ngati mutagwirizanitsa waya wabwino pamtunda wapamwamba ndi waya woipa pa mphamvu yochepa. (1)

  • CAT multimeter mlingo
  • Multimeter voteji chizindikiro chosasintha
  • Chizindikiro chamagetsi a Multimeter
