Uvavanya njani iibhetri zenqwelo yegalufa ngemultimeter?

Ukuvavanya iibhetri zenqwelo yegalufa nge-multimeter yindlela ekhawulezayo nesebenzayo yokujonga impilo yabo. Nali inyathelo ngenyathelo isikhokelo:

Yintoni oya kuyidinga:

• Imultimitha yeDijithali (enokusetha umbane weDC)

• Iiglavu zokhuseleko kunye nokhuseleko lwamehlo

Ukhuseleko Kuqala:

• Cima inqwelo yegalufa kwaye ususe isitshixo.

• Qinisekisa ukuba indawo leyo inomoya owaneleyo.

• Nxiba iiglavu kwaye uphephe ukubamba zombini iitheminali zebhetri ngexesha elinye.

Inyathelo ngalinye imiyalelo:

1. Seta iMultimeter

• Jika umnxeba kuyeI-DC Voltage (V⎓).

• Khetha uluhlu olungaphezulu kombane webhetri yakho (umzekelo, 0–200V kwiisistim ezingama-48V).

2. Chonga iBattery Voltage

• Iinqwelo zegalufa zidla ngokusetyenziswa6V, 8V, okanye 12V iibhetrikuthotho.

• Funda ileyibhile okanye ubale iiseli (iseli nganye = 2V).

3. Vavanya iibhetri zomntu ngamnye

• Beka iprobe ebomvukwiItheminali elungileyo (+).

• Beka iuphando olumnyamakwiItheminali ethabathayo (−).

• Funda amandla ombane:

  • 6V ibhetri: Kufuneka ufunde ~ 6.1V xa uhlawulwe ngokupheleleyo

  • 8V ibhetri: ~ 8.5V

  • 12V ibhetri: ~ 12.7–13V

4. Vavanya iPakethi iyonke

• Beka i-probes kwi-positive yebhetri yokuqala kunye ne-negative terminals yebhetri yokugqibela kuthotho.

• Ipakethi ye-48V kufuneka ifundwe~50.9–51.8Vxa ihlawuliswe ngokupheleleyo.

5. Thelekisa ufundo

• Ukuba kukho ibhetringaphezulu kwe-0.5V esezantsikunabanye, isenokuba buthathaka okanye isilele.

UVavanyo loMlayisho ngoKhenketho (Uguqulelo olulula)

• Emva kokuvavanya i-voltage ekuphumleni,qhuba inqwelo kangangemizuzu eyi-10–15.

• Emva koko phinda uvavanye umbane webhetri.

  • A ukuhla kwamandla ombane okubalulekileyo(ngaphezulu kwe-0.5–1V ngebhetri nganye
