He aha ka manaʻo o ka voluma maikaʻi ʻole ma kahi multimeter?
Nā mea
ʻO ka multimeter e ana i ka volta, ka manawa a me ke kū'ē. Ma ke ʻano maʻamau, he maikaʻi a maikaʻi ʻole paha ka heluhelu multimeter, a pono ʻoe e ʻike maikaʻi i ka uila i mea e ana i ka heluhelu. ʻO nā helu helu multimeter maikaʻi ʻole, he aha ke ʻano?
ʻO ka heluhelu ʻana i ka voltase maikaʻi ʻole ma ka multimeter ʻo ia ka mea i kēia manawa ka nui o nā electrons. I loko o ia kūlana, loaʻa ka mea i ka hoʻopiʻi ʻino.
He aha kāu e pono ai e nānā i ka volta ma kahi multimeter?
Eia nā mea a pau e pono ai ʻoe e nānā i ka volta ma kāu multimeter:
- Hoʻopiha multimeter
- Puna o ka lako mana pau ole
- ʻIke maikaʻi o ka uila a me ka ʻepekema e hoʻomaopopo i ka heluhelu
Pehea e ana au i ka volta me ka multimeter?
ʻO ka Voltage kekahi o nā māla i hiki ke ana ʻia me ka multimeter. I kēia manawa, hiki ke loaʻa nā multimeter analog a me nā digital ma ka mākeke. Ma kēia alakaʻi, e nānā mākou i ke ʻano maʻamau no ke ana ʻana i ka volta me kahi multimeter, pili a pili i nā anana a me nā multimeter kikohoʻe.
KaʻAnuʻu 1 - Ke ana nei ʻoe i ka voltage? Inā pēlā, ʻo ka volta DC a i ʻole AC? Inā ʻoe e ana ana i ka volta ma kou home, ʻo ia paha ka AC, akā inā he kaʻa a i ʻole ka mea hoʻohana ʻia i ka pākaukau, a laila ʻo ia ka DC.
KaʻAnuʻu 2 - E hoʻohuli i ka hoʻololi koho i ka volta kūpono āu i manaʻo ai e ana. Hōʻike ʻia ka volta AC e kahi hawewe sine. No DC, he laina pololei ia me kahi laina kiko ma lalo iho.
KaʻAnuʻu 3 - E huli i ka puka COM ma kāu multimeter a hoʻohui i ke alakaʻi ʻeleʻele.
KaʻAnuʻu 4 - E huli i ka mea hoʻohui i kaha ʻia V a hoʻopili i ke alakaʻi ʻulaʻula.
KaʻAnuʻu 5 - No ke ʻano o ka volta kūpono, e hoʻonoho i ka hoʻololi koho i ka waiwai nui.
KaʻAnuʻu 6 - E ho'ā i ka hāmeʻa, kaʻa, a i ʻole ka uila nona ka uila āu e ana e ana.
KaʻAnuʻu 7 - E hōʻoia i ka pili ʻana o ka ʻeleʻele a me ka ʻulaʻula i nā welau ʻelua o nā ʻāpana o ka mea āu e ana ana i ka volta.
KaʻAnuʻu 8 - E ʻike ʻia kāu heluhelu ʻana i ka volta ma ka pale multimeter.
Pehea e heluhelu ai a hoʻomaopopo i ka heluhelu voltage?
ʻElua wale nō ʻano o nā heluhelu voli e hōʻike ʻia ma ka multimeter: nā heluhelu maikaʻi a me nā heluhelu ʻino.
Ma mua o ka lele ʻana i ka heluhelu, e hoʻomanaʻo i kēlā me kēia multimeter, hōʻike ka ʻulaʻula i ka maikaʻi a ʻo ka ʻeleʻele e hōʻike i ka maikaʻi ʻole. Pili pū kēia i nā mea ʻike a me nā hōʻailona ʻē aʻe a me nā uea.
ʻO ka waiwai maikaʻi ʻole, ʻaʻole ia i loko o kahi kūlana passive ke kaapuni i hoʻohana ʻia. Loaʻa iā ia kahi ʻāʻī. ʻO ke kumu kūʻai o ka voltage maikaʻi ʻole ma muli o ka nui o nā electrons. ʻO ka heluhelu maikaʻi ka mea kū'ē i kēia. E hōʻike ana ka multimeter i ka waiwai maikaʻi inā hoʻopili ʻoe i ka uea maikaʻi ma kahi hiki ke kiʻekiʻe aʻe a me ka uea maikaʻi ʻole ma kahi hiki haʻahaʻa. (1)
