Mokhoa oa ho lekola libeteri tsa kolofo ea kolofo ka multimeter?

Ho etsa liteko tsa libeteri tsa koloi ea kolofo ka multimeter ke mokhoa o potlakileng le o sebetsang oa ho lekola bophelo ba bona. Mona ke tataiso ea mohato ka mohato:

Seo U tla se Hloka:

• Multimeter ea dijithale (e nang le boemo ba motlakase oa DC)

• Liatlana tsa tšireletso le tšireletso ea mahlo

Polokeho Pele:

• Koala kariki ea kolofo 'me u tlose senotlolo.

• Netefatsa hore sebaka seo se na le moea o motle.

• Apara liatlana 'me u qobe ho tšoara litheminale tsa betri ka nako e le ngoe.

Litaelo ka Mohato:

1. Beha Multimeter

• Fetolela ho daela hoDC Voltage (V⎓).

• Khetha sebaka se phahameng ho feta matla a betri ea hau (mohlala, 0–200V bakeng sa lisebelisoa tsa 48V).

2. Khetholla Battery Voltage

• Hangata likoloi tsa kolofo li sebelisoa6V, 8V, kapa 12V libeterika letoto.

• Bala leibole kapa bala lisele (sele ka 'ngoe = 2V).

3. Leka Libetri tsa Motho ka Mong

• Beha sebakaphuputso e khubeluhoterminal e ntle (+).

• Beha sebakaphuputso e ntšohoterminal e mpe (−).

• Bala motlakase:

  • 6V betri: E lokela ho bala ~ 6.1V ha e qositsoe ka botlalo

  • 8V betri: ~ 8.5V

  • 12V betri: ~ 12.7–13V

4. Leka Pakete E feletseng

• Beha li-probe ho li-terminal tsa betri tsa pele tse ntle le tsa morao-rao tse mpe letotong.

• Pakete ea 48V e lokela ho baloa~ 50.9–51.8Vha e qositsoe ka botlalo.

5. Bapisa Lipalo

• Haeba ho na le betriho feta 0.5V tlaseho feta tse ling kaofela, e ka 'na ea fokola kapa ea hlōleha.

Teko ka Boikhethelo ea Mojaro (Mofuta o Bonolo)

• Ka mor'a ho hlahloba voltage ha u phomotse,khanna koloi bakeng sa metsotso e 10-15.

• Ebe u hlahloba matla a betri hape.

  • A ho theoha ho hoholo ha motlakase(ho feta 0.5–1V betri ka 'ngoe
