Indlela yokuhlola amabhethri enqola yegalofu nge-voltmeter?

Ukuhlola amabhethri akho enqola yegalofu nge-voltmeter kuyindlela elula yokuhlola impilo yawo kanye nezinga lokushaja. Nansi inkomba yesinyathelo ngesinyathelo:

Amathuluzi Ayadingeka:

• I-voltmeter yedijithali (noma i-multimeter isethwe ku-DC voltage)

• Amagilavu ​​okuphepha nezingilazi (ongakukhetha kodwa kuyanconywa)

Izinyathelo Zokuhlola Amabhethri Enqola Igalofu:

1. Ukuphepha Kuqala:

• Qinisekisa ukuthi inqola yegalofu IVALIWE.

• Uma ubheka amabhethri ngamanye, susa noma yibuphi ubucwebe bensimbi futhi ugweme ukufinyeza amatheminali.

2. Nquma I-Voltage Yebhethri:

• Amabhethri angu-6V (avamile ezinqoleni ezindala)

• Amabhethri angu-8V (avamile kumakalishi angu-36V)

• Amabhethri angu-12V (avamile kumakalishi angu-48V)

3. Hlola amabhethri angawodwana:

• Setha i-voltmeter ibe yi-DC Volts (20V noma ibanga eliphezulu).

• Thinta ama-probe:

  • I-probe ebomvu (+) eya kutheminali ephozithivu.

  • Uphenyo olumnyama (–) oluya kutheminali enegethivu.

• Funda i-voltage:

  • 6V ibhethri:

    • Ishajwe ngokugcwele: ~6.3V–6.4V

    • 50% ekhokhisiwe: ~ 6.0V

    • Ikhishwe: Ngaphansi kwe-5.8V

  • 8V ibhethri:

    • Ishajwe ngokugcwele: ~8.4V–8.5V

    • 50% eshajiwe: ~8.0V

    • Ikhishwe: Ngaphansi kwe-7.8V

  • 12V ibhethri:

    • Ishajwe ngokugcwele: ~12.7V–12.8V

    • 50% ekhokhisiwe: ~12.2V

    • Ikhishwe: Ngaphansi kwe-12.0V

4. Hlola Iphakethe Lonke (Ingqikithi Yamandla Kagesi):

• Xhuma i-voltmeter kokuphozithivu okuyinhloko (ibhethri lokuqala +) kanye nenegethivu eyinhloko (ibhethri lokugcina –).

• Qhathanisa ne-voltage elindelekile:

  • Isistimu engu-36V (amabhethri angu-6V ayisithupha):

    • Ishajwe ngokugcwele: ~38.2V

    • 50% okhokhisiwe: ~36.3V

  • Isistimu engu-48V (amabhethri angu-8V ayisithupha noma amabhethri amane angu-12V):

    • Ishajwe ngokugcwele (amabhethi angu-8V): ~50.9V–51.2V

    • Ishajwe ngokugcwele (amabhethi angu-12V): ~50.8V–51.0V

5. Ukuhlolwa Komthwalo (Ongakukhetha kodwa Kuyanconywa):

• Shayela inqola imizuzu embalwa uphinde uhlole ama-voltage.

• Uma i-voltage yehla kakhulu ngaphansi komthwalo, ibhethri elilodwa noma amaningi angase abe buthaka.

6. Qhathanisa Wonke Amabhethri:

• Uma ibhethri elilodwa lingaphansi ngo-0.5V–1V kunamanye, kungenzeka liyehluleka.

Ungawashintsha Nini Amabhethri:

• Uma noma yiliphi ibhethri lingaphansi kokushajwa okungu-50% ngemva kokushajwa okugcwele.

• Uma i-voltage yehla ngokushesha ngaphansi komthwalo.

• Uma ibhethri elilodwa lihlezi liphansi kunamanye.
