Multimeter vs Voltmeter: He aha ka ʻokoʻa?

Inā hauʻoli ʻoe i ka hana ʻana me ka uila, pono ʻoe e ʻike he mea pono loa nā multimeters a me nā voltmeters i nā ʻano hana he nui. Eia nō naʻe, hiki ke huikau pinepine i kekahi poʻe i ka mea i kūpono i ko lākou pono. ʻOiai ua maopopo iā mākou he manaʻo maʻamau paha ʻoe i ke ʻano o kēlā me kēia mea hana, hiki ke kōkua nui ka nānā ʻana i ka wā e hana ai i kahi papahana.

No ke kōkua ʻana iā ʻoe e hoʻomaopopo maikaʻi i kēia mau mea hana ʻelua a me ka ʻokoʻa ma waena o lākou, e heluhelu i kēia alakaʻi maʻalahi a hoʻomaopopo. E ʻimi mākou i nā hiʻohiʻona o kēlā me kēia hāmeʻa a pehea lākou e ʻokoʻa ai kekahi i kekahi e pili ana i ka hana.

ʻO ka voltmeter kahi mea hana maʻalahi e ana i ka volta. ʻO ka multimeter, ma ka ʻaoʻao ʻē aʻe, hāʻawi i nā koho he nui, akā ʻoi aku ka maikaʻi no ke kumu like. ʻO kēia ka hopena i ka ʻokoʻa nui o kā lākou kumukūʻai no ka mea ʻoi aku ka nui o nā multimeters.

Multimeter vs voltmeter: ʻo wai kahi e koho ai?

He hoʻoholo kēia e pono ai ʻoe e hana ma muli o ka hana ʻana o kēlā me kēia hāmeʻa. ʻO ka mea nui, pili ia i ke ʻano o ke ana āu e makemake ai a me ka nui o ke kālā āu e hiki ai ke hoʻolilo. Ma ka hoʻomaopopo ʻana i kāu mau pono, pono ʻoe e hoʻoholo i kahi o nā mea ʻelua e lawelawe maikaʻi iā ʻoe.

E heluhelu pono i ka ʻike e pili ana i kēlā me kēia mea hana e ʻike ai i ka hana a kēlā me kēia mea a pehea e pili ai i kāu hoʻoholo.

Ka hoomaopopo ana i ka hana o ka Voltmeter

ʻO ka hana nui o ka voltmeter ke ana i ka volta e hele ana ma waena o ʻelua mau nodes. Mai ka ʻike loea, ʻo ka volt kahi ʻāpana o ka ʻokoʻa kūpono ma waena o nā nodes ʻelua, a ua ana ʻia kēia ʻokoʻa i nā volts. ʻO ka voltage ponoʻī e hele mai i ʻelua ʻano no ka mea he ʻelua ʻano ʻano o kā mākou ʻano ʻo ia hoʻi ke au pololei (DC) a me ke au hou (AC). ʻO kekahi mau voltmeters e ana i ke au pololei, a ʻo nā mea ʻē aʻe e ana i ke au ʻokoʻa wale nō. A laila loaʻa iā ʻoe ke koho o nā voltmeters e ana ʻelua ma ka mea like.

He mea maʻalahi loa ka hana ʻana i loko o kahi mea hōʻike uila a loaʻa wale i kahi wili o ka uea lahilahi e lawe ana i kahi au i hoʻokuʻu ʻia a puni kahi kahua magnetic waho. Hele mai ka hāmeʻa me ʻelua mau puʻupuʻu, ke hoʻopili ʻia i ʻelua mau nodes, e hoʻokele i kēia manawa ma o ke kelepona i loko. ʻO kēia ke kumu o ka uwea e hoʻololi i ke kahua magnetic, a hoʻomaka ka ʻōwili ma luna o ia mea e hoʻololi. Hoʻoneʻe kēia i ke ana ʻana ma ka hōʻike, e hōʻike ana i ka waiwai volta. ʻOi aku ka palekana o nā voltmeter kikohoʻe ma mua o nā mika nila a loaʻa nui i kēia mau lā. (1)

Eversame Flat US Plug AC 80-300V LCD Digital Voltmeter

ʻOiai ʻo ka mea hōʻike uila i wehewehe ʻia ma luna e ana i nā kikoʻī like ʻole, hiki iā ʻoe ke ʻike i nā mea hiki ke wehe ʻia e like me ka Eversame Flat US Plug AC 80-300V LCD Digital Voltmeter, e hōʻike ana i ke kahe e kahe ana ma kahi puka pā kikoʻī. Hoʻohana ʻia ia e nānā i nā hāmeʻa i hoʻopili ʻia i loko o nā puka waho a hiki ke kōkua i ka pale ʻana i ka pōʻino uila i ka wā e piʻi ai ka mana.

He aha ka hana a ka multimeter?

Hoʻokahi mea hiki i ka multimeter ke hana e like me ka voltmeter. No laila, inā ʻoe e kūʻai aku i kahi multimeter analog, e hoʻokō ʻoe i kou pono no kahi voltmeter. Hiki i ka multimeter ke ana i ka volta a me nā ʻāpana uila e like me ke au a me ke kū'ē. ʻO nā multimeter hou aʻe e ana i nā ʻāpana e like me ka capacitance, ka mahana, ka pinepine, ka inductance, ka acidity, a me ka haʻahaʻa pili.

ʻOi aku ka paʻakikī o nā mea i loko o ka multimeter a me nā mea ʻē aʻe e like me nā resistors, capacitors, nā ʻike wela, a me nā mea hou aku. Mai kahi hiʻohiʻona ʻenehana maʻemaʻe, maʻalahi ka ʻike ʻana he mea ʻoi aku ka hana o ka multimeter ma mua o ka voltmeter maʻalahi.

UYIGAO TRMS 6000 kikohoʻe multimeter

ʻO kahi laʻana o ka voltmeter hana kiʻekiʻe ʻo ka UYIGAO TRMS 6000 digital multimeter, kahi hāmeʻa e hāʻawi ana i nā koho ana e koho ai. Me kēia hāmeʻa, hiki iā ʻoe ke ana i nā ʻāpana he nui o ke ana, me ka mahana, capacitance, AC voltage, AC current, DC voltage, DC current, frequency, and resistance.

Hāʻawi ka hāmeʻa i nā hiʻohiʻona kūikawā ʻē aʻe e like me ka beep, kaʻa a me ka manual ranging, NCV detection, a me ka mana kaʻa e hoʻopau i ka mana pākaukau. Hōʻike pū ka hāmeʻa i kahi hōʻike 3-inch nui e maʻalahi ke heluhelu a me ka backlit. He kūpono ia no ka hoʻohana ʻoihana a he hale paʻa kona e pale aku ai i ka pōʻino ke hāʻule. Hiki nō hoʻi iā ʻoe ke kau iā ia ma kahi pālahalaha me ka hoʻohana ʻana i ke kū i hoʻokomo ʻia. (2)

E hōʻuluʻulu

I kēia manawa, ua maopopo paha iā ʻoe he ʻokoʻa loa kēia mau mea ʻelua mai kekahi i kekahi e pili ana i kā lākou hana. He mea maʻalahi ka voltmeter akā hiki ke hele mai i nā ʻano like ʻole a me nā nui no ka hoʻohana paʻa a maʻalahi. ʻO ia hoʻi ke koho ʻoi aku ka liʻiliʻi o nā mea ʻelua, akā ʻo ia hoʻi ma muli o kāna hana liʻiliʻi. ʻO nā multimeters, ma ka ʻaoʻao ʻē aʻe, he mau mea hana maʻalahi loa e hiki ke lawelawe iā ʻoe i kahi ākea o nā noi, akā pono ʻoe e hoʻopuka i nā kālā hou aku inā makemake ʻoe. E noʻonoʻo i kāu mau pono a hiki iā ʻoe ke koho maʻalahi i ka mea e kūpono iā ʻoe.

E nānā i kekahi o kā mākou ʻatikala ma lalo nei.

• Pehea e ana i ka volta DC me ka multimeter
• Pehea e heluhelu ai i ka multimeter analog
• ʻO ka hōʻailona uila uila
