Ungazivavanya njani iibhetri zenqwelo yegalufa nge-multimeter?

Ukuvavanya iibhetri zenqwelo yegalufa nge-multimeter yindlela ekhawulezayo nesebenzayo yokujonga impilo yazo. Nantsi isikhokelo senyathelo ngenyathelo:

Oko Uza Kukufuna:

• I-multimeter yedijithali (ene-DC voltage setting)

• Iiglavu zokhuseleko kunye nokukhusela amehlo

Ukhuseleko Kuqala:

• Cima inqwelo yegalufa uze ususe isitshixo.

• Qinisekisa ukuba indawo inomoya ococekileyo.

• Nxiba iiglavu kwaye uphephe ukuchukumisa zombini iiterminal zebhetri ngaxeshanye.

Imiyalelo yeNyathelo ngeNyathelo:

1. Seta iMultimeter

• Jika idayali ibeI-DC Voltage (V⎓).

• Khetha uluhlu oluphezulu kunevolthi yebhetri yakho (umz., 0–200V kwiinkqubo ze-48V).

2. Chonga iVolthi yeBhetri

• Iinqwelo zegalufa ezisetyenziswa kakhuluIibhetri ze-6V, 8V, okanye ze-12Vkuthotho.

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

3. Vavanya iibhetri zomntu ngamnye

• Beka iiprobe ebomvukwiisiphelo esihle (+).

• Beka iiprobe emnyamakwiisiphelo esingalunganga (−).

• Funda i-voltage:

  • Ibhetri ye-6V: Ifanele ifundeke ~6.1V xa itshajiwe ngokupheleleyo

  • Ibhetri ye-8V: ~8.5V

  • Ibhetri ye-12V: ~12.7–13V

4. Vavanya iPhekhi yonke

• Beka iiprobes kwi-terminals zebhetri yokuqala ezine-positive kunye ne-negative zebhetri yokugqibela kuthotho.

• Iphakheji ye-48V ifanele ifundeke~50.9–51.8Vxa itshajwe ngokupheleleyo.

5. Thelekisa uFundo

• Ukuba kukho ibhetringaphezulu kwe-0.5V esezantsikunezinye, isenokuba buthathaka okanye ingasebenzi kakuhle.

Uvavanyo loMthwalo oluKhethekileyo (Uhlobo oluLula)

• Emva kokuvavanya i-voltage xa ​​uphumle,qhuba inqwelo imizuzu eli-10–15.

• Emva koko vavanya kwakhona i-voltage yebhetri.

  • A ukwehla okukhulu kwe-voltage(ngaphezulu kwe-0.5–1V ngebhetri nganye
