Ungawahlola kanjani amabhethri enqola yegalofu nge-multimeter?

Ukuhlola amabhethri enqola yegalofu nge-multimeter kuyindlela esheshayo nephumelelayo yokuhlola impilo yawo. Nasi umhlahlandlela wesinyathelo ngesinyathelo:

Okuzodingayo:

• I-multimeter yedijithali (enezilungiselelo ze-DC voltage)

• Amagilavu ​​​​okuphepha kanye nokuvikela amehlo

Ukuphepha Kuqala:

• Cima inqola yegalofu bese ususa ukhiye.

• Qinisekisa ukuthi indawo inomoya omuhle.

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

Imiyalelo Yesinyathelo Ngesinyathelo:

1. Setha i-Multimeter

• Jikisa idayari ibeI-DC Voltage (V⎓).

• Khetha ububanzi obuphakeme kune-voltage yebhethri lakho (isb., 0–200V yezinhlelo ze-48V).

2. Thola i-Voltage yebhethri

• Izinqola zegalofu ezivame ukusetshenziswaAmabhethri angu-6V, 8V, noma angu-12Vochungechungeni.

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

3. Hlola Amabhethri Ngamunye

• Bekai-probe ebomvuuseisiphetho esihle (+).

• Bekai-probe emnyamausei-terminal engalungile (−).

• Funda i-voltage:

  • Ibhethri le-6V: Kufanele kufundeke ~6.1V uma kushajwe ngokugcwele

  • Ibhethri le-8V: ~8.5V

  • Ibhethri le-12V: ~12.7–13V

4. Hlola Iphakethe Lonke

• Beka ama-probe kuma-terminal ebhethri lokuqala ane-positive kanye nama-terminal ebhethri lokugcina ane-negative ochungechungeni.

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

5. Qhathanisa Ukufundwa

• Uma kukhona ibhethringaphansi kuka-0.5Vkunezinye, kungase kube buthakathaka noma kwehluleka.

Ukuhlolwa Komthwalo Ongakukhetha (Inguqulo Elula)

• Ngemva kokuhlola i-voltage ngesikhathi sokuphumula,shayela inqola imizuzu eyi-10-15.

• Bese uphinde uhlole i-voltage yebhethri.

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