Ma lalo wau e aʻo iā ʻoe pehea e hoʻāʻo ai i kahi fuse me kahi multimeter. Pono ʻoe e nānā i loko o ka fuse e hele maoli i lalo o nā mea a ʻike inā ua puhi ʻia. E aʻo aku au iā ʻoe pehea e hana ai ma lalo nei.

ʻO nā hana koʻikoʻi a mākou e hele ai:

Hāʻawi ʻia i ka volta o ka fuse.
Ana ohm
Ke nānā nei i nā fuse i loko o ka pahu fuse
Ana kūʻē fuse puhi
Ke nānā nei i ke kūlana o nā kaapuni i kēia manawa

Inā he heluhelu kāu ma waena o 0 - 5 ohms (ohms), maikaʻi ka fuse. ʻO kēlā me kēia waiwai kiʻekiʻe, ʻo ia hoʻi, he fuse maikaʻi ʻole a kīnā ʻole paha. inā heluhelu ʻoe iā OL (ma luna o ka palena) ʻo ia ka manaʻo he fuse puhi.

Pehea e nānā ai me ka multimeter inā puhi ʻia ka fuse?

I kēia hihia, e nānā inā fuse puhi ʻia e ka ʻike maka ʻaʻole lawa paha. No laila, pono ʻoe e hoʻohana i ka multimeter e hoʻopau i nā kānalua āpau.

ʻO kāu koho maikaʻi loa ʻo ka hana ʻana i kahi hoʻāʻo uila a nānā i ka hewa o ka fuse.

ʻO ka mea mua, pono ʻoe i ke ʻano hoʻomau ma kāu multimeter. Loaʻa ka hapa nui o nā multimeter maikaʻi loa i kēia ʻano hoʻohana. A laila pono e kau ʻia kekahi o nā ʻimi ma kekahi ʻaoʻao o ka fuse. ʻOiaʻiʻo, pono e kau ʻia ka ʻimi ʻē aʻe o kāu multimeter ma kekahi ʻaoʻao o ka fuse like.
Eia ka pahuhopu nui e hoʻoholo inā maikaʻi ka fuse. No laila, ma ke ʻano hoʻomau, pono e kani ka multimeter e hōʻike i ka hoʻomau.
Inā hiki iā ʻoe ke nānā no ka hoʻomau ʻana, ʻaʻole puhi ʻia ka fuse. I nā huaʻōlelo ʻē aʻe, ʻo ia hoʻi, ʻaʻohe pilina i hoʻopōʻino a hāʻule paha.
ʻO ka mea ʻē aʻe, hiki paha i ka multimeter ke hōʻike i kahi kiʻekiʻe o ke kūʻē me ke kani ʻole. No laila, i ka wā e hiki mai ai kēia, ʻo ke kumu nui ua puhi mua ka fuse a no laila ʻaʻole pono.
Hiki iā ʻoe ke hoʻohana i ka multimeter ohmmeter inā ʻaʻole ia he ʻano hoʻomau. No laila, pono ʻoe e koho i kahi ohmmeter a kau i kēlā me kēia nalu ma kēlā me kēia kihi o ka fuse.
Inā paʻa ka fuse, haʻahaʻa ka heluhelu ohmmeter. ʻO ka mea ʻē aʻe, e kiʻekiʻe loa ka heluhelu inā ʻeha a puhi ʻia ka fuse. (Maikaʻi ka fuse inā ʻo kona heluhelu ʻana ma waena o 0 a me 5 ohms (Ω).. ʻO kēlā me kēia waiwai kiʻekiʻe, ʻo ia hoʻi, he fuse maikaʻi ʻole a kīnā ʻole paha. Ina ʻO kāu heluhelu ʻana ʻo OL (Over the Limit), ʻo ia hoʻi he fuse puhi.)

Pehea e ʻike ai inā ʻino ka fuse?

ʻO kēia kahi e nānā ai i ke olakino o ka fuse e ʻae iā ʻoe e pale i nā kūlana maʻamau i ʻike ʻole ʻia. Eia naʻe, ʻaʻole loaʻa ka fuse maikaʻi i nā manawa a pau, no laila pono ʻoe e aʻo pehea e nānā ai i ke ʻano o ka fuse. Hiki iā ʻoe ke hoʻohana i ka multimeter a i ʻole hiki iā ʻoe ke hoʻoholo koke inā pau ka fuse.

ʻAʻole paʻakikī loa ka ʻimi ʻana i kahi fuse puhi. I kekahi manawa, heheʻe a haki paha ka mea hoʻohui fuse nui.

Inā ʻaʻole hiki iā ʻoe ke hōʻoia i kēia, hiki iā ʻoe ke hoʻomau i ka hoʻohana ʻana i ka multimeter. ʻO ka mea maʻamau, inā ua haki ka mea hoʻohui i ka fuse, ʻaʻohe mea i koe e hana akā hoʻoponopono. ʻO ka mea ʻē aʻe, ʻoi aku ka maikaʻi o ka fuse inā ʻaʻole hehee ka mea hoʻohui i loko. Pono kēia mea hoʻohui i ke kūlana maikaʻi mai kekahi ʻaoʻao o ka fuse a i kekahi.

ʻOi aku ka maikaʻi inā loaʻa iā ʻoe kahi fuse hou e pani ai i ka mea puhi. ʻOiaʻiʻo, nui nā fuses i loaʻa ma ka mākeke. No laila pono ʻoe e hōʻoia i ke ʻano o ka fuse hou me ka mea kahiko.

Pehea e nānā ai i ka fuse a me ka relay me ka multimeter?

No ka hoʻāʻo ʻana i kahi fuse me kahi multimeter, pono ʻoe e hoʻohana i ke ʻano hoʻomau ma ka multimeter.
ʻOi aku ka maikaʻi inā hoʻopili ʻoe i nā alakaʻi multimeter i kēlā me kēia hopena o ka fuse. Inā hiki iā ʻoe ke hoʻoholo i ka hoʻomau ma ka multimeter, maikaʻi ka fuse. ʻO ka mea ʻē aʻe, he fuse puhi ke ʻole ʻoe e ʻike i ka hoʻomau i kāu multimeter.
Ma ka ʻaoʻao ʻē aʻe, hiki iā ʻoe ke nānā inā maikaʻi ke kūlana coil relay a i ʻole. ʻOi aku ka maikaʻi inā loaʻa iā ʻoe kahi multimeter digital me ʻehiku mau hana no kēia.
I kēia hihia, pono e hoʻohana i ke ʻano kūʻē ma waena o kēlā me kēia pou o ka relay. Eia ka helu helu ʻana ma ka pou pili o nā mea pili a pau. (1)
I ka manawa like, pono e mālama ʻia nā pilina ma kēia wahi e like me ka heluhelu kūʻē kūʻē ʻole inā kau ʻoe i nā ʻimi ma ka pou kūpono. A laila hiki iā ʻoe ke hoʻomau ma hope o ka hoʻohuli ʻana i ka relay. E lohe ʻoe i kahi kaomi ke hoʻoikaika ʻia ka relay.
A laila pono ʻoe e hana hou i ke kaʻina hana me kahi multimeter. Maʻaneʻi, pono e lawa ke kū'ē o ka wehe a me ka pani pani. Hiki iā ʻoe ke hoʻāʻo i nā relay kūlana paʻa me kahi multimeter. (2)
I kēia hihia, pono ʻoe i kahi heluhelu diode e hoʻāʻo ai i kēia ʻano relay. E hōʻike ka multimeter i ka volta i hoʻopili ʻia i ka relay. E hōʻike ana ka counter i ka zero a i ʻole OL ke hana ʻole ka relay.
ʻO ka mea ʻē aʻe, ʻo kahi relay i ke kūlana maikaʻi e hāʻawi i ka hopena o 0.5 a i ʻole 0.7, ma muli o ke ʻano o ka relay.
ʻOi aku ka maʻalahi a maʻalahi hoʻi ka hoʻoponopono ʻana i nā relays solid state.

Loaʻa iā mākou nā ʻatikala HOW-TO hiki iā ʻoe ke nānā a me ka bookmark no ka ʻike e hiki mai ana. Eia kekahi o ia mau mea: "Pehea e hoʻokani ai i ka amplifier me ka multimeter" a me "Pehea e hoʻohana ai i ka multimeter e nānā i ka volta o nā uea ola." Manaʻo mākou e kōkua kēia kumu aʻo iā ʻoe.
