Ungawahlola kanjani amabhethri enqola yegalofu nge-multimeter?

Ukuhlola amabhethri enqola yegalofu nge-multimeter kuyindlela esheshayo nesebenzayo yokuhlola impilo yabo. Nansi inkomba yesinyathelo ngesinyathelo:

Okuzodinga:

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

• Amagilavu ​​okuphepha nokuvikela iso

Ukuphepha Kuqala:

• Vala inqola yegalofu bese ukhipha ukhiye.

• Qinisekisa ukuthi indawo inomoya omuhle.

• Gqoka amagilavu ​​futhi ugweme ukuthinta womabili amatheminali ebhethri ngesikhathi esisodwa.

Isinyathelo ngesinyathelo Imiyalelo:

1. Setha i-Multimeter

• Vula ukudayela ku-I-DC Voltage (V⎓).

• Khetha ububanzi obuphezulu kunomthamo webhethri lakho (isb, 0–200V kumasistimu angu-48V).

2. Khomba I-Voltage Yebhethri

• Izinqola zegalofu zivame ukusetshenziswa6V, 8V, noma 12V amabhethriochungechungeni.

• Funda ilebula noma ubale amaseli (iseli ngalinye = 2V).

3. Hlola amabhethri angawodwana

• Beka i-uphenyo olubomvuuseitheminali enhle (+).

• Beka i-uphenyo olumnyamauseitheminali enegethivu (−).

• Funda i-voltage:

  • 6V ibhethri: Kufanele ifunde ~6.1V uma ishajwe ngokugcwele

  • 8V ibhethri: ~ 8.5V

  • 12V ibhethri: ~12.7–13V

4. Hlola Iphakethe Lonke

• Beka ama-probe kumatheminali ebhethri eliphozithivu nelokugcina elinegethivu ochungechungeni.

• Iphakethe le-48V kufanele lifundeke~50.9–51.8Vuma ishajwe ngokugcwele.

5. Qhathanisa Ukufundwa

• Uma kukhona ibhethringaphansi kuka-0.5Vkunabanye, kungase kube buthaka noma kwehluleke.

Ukuhlolwa Komthwalo Ongakukhetha (Inguqulo Elula)

• Ngemuva kokuhlola i-voltage lapho uphumule,shayela inqola imizuzu eyi-10-15.

• Bese uphinde uhlole i-voltage yebhethri.

  • A ukwehla okukhulu kwamandla kagesi(ngaphezu kuka-0.5–1V ibhethri ngalinye
