Hōʻailona Diode Multimeter (Manual)
ʻO ka hoʻāʻo ʻana i ka diode ke ala ʻoi aku ka maikaʻi a me ka manawa hou e nānā ai inā maikaʻi a maikaʻi ʻole paha kāu mau diodes. ʻO ka diode kahi mea uila e hiki ai ke kahe ʻana o ke au i kahi kuhikuhi kikoʻī. Loaʻa iā ia nā hopena cathode (negative) a me ka anode (positive).
Ma ka ʻaoʻao ʻē aʻe, ʻo ka multimeter kahi mea ana i hiki ke hoʻohana ʻia no ke ana ʻana i ke kū'ē, ka volta, a me ke au. ʻO nā hōʻailona o ka multimeter aia ma luna ona e kōkua i ka hana ʻana i kāna mau hana like ʻole. Hele pū mai me ke alakaʻi hoʻāʻo. E nānā i ka papa inoa piha ma aneʻi.
I ka pōkole, e hoʻāʻo i kahi diode, pono ʻoe e hana i kēia mau hana. E hoʻohuli mua i ka dial multimeter i ka hōʻailona hōʻike diode a hoʻopau i ka mana i kāu kaapuni. A laila, e hoʻohui i nā ʻōkuhi probe o nā multimeter probes i ka diode. ʻO ke alakaʻi maikaʻi ʻole i ka hopena maikaʻi ʻole (cathode) o ka diode, a ʻo ke alakaʻi maikaʻi i ka hopena maikaʻi (anode) o ka diode, ua hoʻohālikelike ʻia i mua. A laila e loaʻa iā ʻoe kahi heluhelu multimeter. He 0.5 a 0.8V ka waiwai ma'amau no ka diode silicon maika'i a he 0.2 a 0.3V ka diode germanium maika'i. E ho'ololi i nā alaka'i a ho'opā i ka diode ma ka 'ao'ao 'ē a'e, 'a'ole pono e hō'ike ka multimeter i ka heluhelu 'ana ma mua o OL.
Ma kā mākou ʻatikala, e kūkākūkā mākou i nā kikoʻī pehea e hoʻāʻo ai i kahi diode me kahi multimeter.
Hōʻailona diode multimeter
Hōʻike pinepine ʻia ka hōʻailona diode i nā kaapuni ma ke ʻano he huinakolu me kahi laina e hele ana i luna o ka huinakolu. He ʻokoʻa kēia me ka multimeter, ʻo ka hapa nui o nā multimeters he mode hoʻāʻo diode, a no ka hana ʻana i kahi hoʻāʻo diode, pono ʻoe e hoʻohuli i ke kelepona o ka multimeter i ka hōʻailona diode ma ka multimeter. ʻO ka hōʻailona diode ma ka multimeter me he pua e kuhikuhi ana i kahi pahu kūpaʻa kahi e haʻalele mau ai kahi laina.
Nui nā hōʻailona multimeter ma kēlā me kēia multimeter i hāʻawi i nā hana, e like me Hertz, AC voltage, DC current, capacitance, resistance, and diode test, a me nā mea ʻē aʻe. No ka hōʻailona multimeter diode, kuhikuhi ka pua i ka ʻaoʻao maikaʻi a ʻo ka pahu kū i ka ʻaoʻao ʻino.
Nā ho'āʻo diode
ʻOi aku ka maikaʻi o ka hoʻāʻo ʻana i ka diode ma ke ana ʻana i ka hāʻule ʻana o ka volta ma waena o ka diode i ka wā e hiki ai i ka volta ma waena o ka diode ke kahe kūlohelohe maoli, ʻo ia hoʻi. Hoʻohana ʻia nā ʻano ʻelua e hoʻāʻo i nā diodes me kahi multimeter kikohoʻe:
- Ke ano hoao diode: ʻO kēia ke ala maikaʻi loa a hoʻohana pinepine ʻia no ka hoʻāʻo ʻana i nā diodes. Aia kēia hana ma waena o nā hōʻailona o ka multimeter.
- ʻAno kūʻē: He ala ʻē aʻe kēia e hoʻohana ai inā ʻaʻohe ʻano hoʻāʻo diode ka multimeter.
Nā Kaʻina Hana Hoʻāʻo Diode
- E hoʻohuli i ka dial multimeter i ka hōʻailona hoʻāʻo diode ma ka multimeter a hoʻopau i ka mana i kāu kaapuni.
- E hoʻokuʻi i ka ʻaoʻao o ka ʻimi ʻimi multimeter i ka diode. ʻO ke alakaʻi maikaʻi ʻole i ka hopena maikaʻi ʻole (cathode) o ka diode, a ʻo ke alakaʻi maikaʻi i ka hopena maikaʻi (anode) o ka diode, ua hoʻohālikelike ʻia i mua.
- A laila e loaʻa iā ʻoe kahi heluhelu multimeter. ʻO ka waiwai maʻamau no ka diode silikoni maikaʻi ʻo 0.5 a 0.8 V, a ʻo kahi diode germanium maikaʻi ʻo 0.2 a 0.3 V (1, 2).
- E hoʻololi i nā alakaʻi a hoʻopā i ka diode ma ka ʻaoʻao ʻē aʻe, ʻaʻole pono e hōʻike ka multimeter i kahi heluhelu ʻē aʻe ma mua o OL.
E hōʻuluʻulu
Ke heluhelu ʻia ka hoʻāʻo no ka piʻi ʻana i mua, hōʻike ia e ʻae ana ka diode i ka holo ʻana o kēia manawa ma kahi ʻaoʻao. I ka hoʻohuli ʻana, ke hōʻike ka multimeter iā OL, ʻo ia hoʻi ke kaumaha. Hōʻike ka multimeter maikaʻi i ka OL ke hoʻohuli ʻia ka diode maikaʻi.
