pehea e koho ai i ka multimeter

Una o nā pono hana i hoʻohana nui ʻia i ka honua o ka uila a me nā uila, ʻo ia hoʻi e nā ʻenehana a me nā mea hana, ʻo ia nō ka multimeter a multimeter paha. ʻO kahi mea e ʻae ai e ana i nā nui a hana Nānā kumu no kēia ʻano kaapuni.

I ka manawa o e hoʻohālikelike i nā multimika a koho i ka mea kūpono loa, ʻaʻole maopopo ka poʻe āpau. No laila, inā makemake ʻoe e hoʻopukapuka maikaʻi i kāu kālā a loaʻa kahi mea maikaʻi e maikaʻi a pololei i kāna ana ʻana, pono ʻoe e hoʻolohe i kēia alakaʻi i hōʻike ʻia nā mea huna āpau ...

He aha ka multimeter?

pehea e koho ai i ka multimeter, multimeter

Un multimeter, mea hoʻāʻo a multimeter paha, he mea uila e hiki ai ke ana i nā nui uila i nā ana uila AC / DC. ʻO kahi laʻana, hiki iā ʻoe ke ana i nā uila, ka ikaika, nā mana, nā kūpaʻa, nā hiki, a pēlā aku. Hoʻopili pū kekahi i nā hana keu e like me ka nānā ʻana i nā transistors, hāmama kaapuni (hoʻomau), etc. ʻO ia ke kumu i ʻike ʻia ai lākou he poly a multi, ʻoiai hiki iā lākou ke ana i nā mea he nui.

Loaʻa kēia mau ʻano o ka multimera i kekahi ana pono hana i loko, i hui ʻia i hiki ai iā lākou ke hāʻawi i nā ana i kākoʻo ʻia. ʻO ia, aia lākou i kahi voltmeter, kahi ameter, a pēlā aku. Eia kekahi, kākoʻo lākou i ke koho ʻana i kekahi mau nui a i ʻole submultiple o nā mea i kākoʻo ʻia e kūpono i ka pālākiō kūpono.

No ke ana ʻana, loaʻa iā ʻoe nā kaula me kekahi probe me ia pilina e hiki ai ke ana i nā nui like ʻole o ke kaapuni.

  • Uila ʻeleʻele (-): ʻo ka mea i kapa ʻia ʻo COM a i ʻole maʻamau. ʻO ia ka mea e hana no nā nui āpau.
  • Uila ʻulaʻula (+): e hoʻopili ana kēlā kaula ʻea i ka pin me ka denomination o ka nui e ana ʻia, no ka laʻana, e ana i ka uila e pono ʻoe e ʻike i ka pin e hōʻike ana iā V, a i ʻole ke ana ʻana i ka ikaika A, etc.

Ke pau kēia a kau ʻia ka mea koho i ke kūlana o ka nui kūpono e ana ʻia ai, e hoʻopā ana i ka pōʻaiapuni e hōʻike i ka waiwai o ana ma ka paku.

Nā ʻano o ka multimeter

multimeter analog

Aia ʻelua ʻano kumu He aha kāu e ʻike ai inā makemake ʻoe e koho i kahi multimeter:

  • Laulau: He ʻelemakule lākou a ʻoi aku ka maʻamau, ʻoiai makemake pinepine ʻia e ka poʻe loea ma muli o ka pololei a me ka hilinaʻi. E hōʻike i nā hopena, loaʻa iā lākou kahi pale me kahi pālākiō a me kahi nila e māka ana i ka waiwai.
  • Digital: ʻoi aku ka maʻalahi o kēia mau lā a maʻalahi hoʻi i ka hoʻohana ʻana, ʻoiai he LCD kā lākou e hōʻike ai i nā hopena. ʻO lākou ka punahele punahele no ka hapanui, no nā mea hoʻomaka. Ana lākou me ka pololei maikaʻi, akā hoʻonui i ka pololei ke heluhelu i nā ana ma ka hōʻike ʻana i ka helu helu.

ʻO kēlā me kēia ʻano, pono ʻoe kali iki, ʻoiai ʻaʻole e kūpaʻa nā kumukūʻai ma ka pakuhi a hiki i ka hala ʻana o kekahi mau manawa. No laila, ʻo ka waiwai mua i ʻike ʻia ʻaʻole paha ʻo ia ka ʻoi.

Pehea e hoʻohana ai i ka multimeter

pehea e koho ai i ka multimeter, pehea e hoʻohana ai

Ke hoʻohana nei i kahi multimeter he pololei. E hilinaʻi nā mea āpau i ka nui āu e makemake ai e ana. ʻO nā mea maʻamau ʻo:

  • Anakahi uila a uila paha: me ka hoʻohui ʻana i ke kaula ʻulaʻula ma ka plug V a me ka mea koho ma ka anakahi kūpono (mV, V, kV ...) kahi kaapuni DC me nā uila kiʻekiʻe loa). haʻahaʻa i kahi laina uila o ka hale ma 220V approx.). I ka manawa e mākaukau, koho i nā kikowaena ʻelua a i ʻole nā ​​kiko i waena o kahi āu e makemake ai e ana i ka hiki a i ʻole ka uila ʻokoʻa a e hōʻike ʻia ma ka pakuhi. E hoʻomanaʻo e hoʻohana i ka uea ʻeleʻele no ka honua / lepo.
  • Nā Kūʻē: koho hou ʻoe i ka mea koho i ka anakahi no nā resistors a me ka pālākiō kūpono, me ka hoʻohui i ka uea ʻulaʻula i ke plug no nā mea pale (Ω). I kēia manawa he mea ia e hoʻopā aku me nā ʻōlelo ʻelua o nā kuʻi ma waena o nā kiko kahi āu e makemake ai e ana i ke kūʻē, e like me nā ʻaoʻao ʻelua o ke kūʻē a e ʻike ʻia ka waiwai ma ka pakuhi.
  • Ikaika: no ka mea o kēia manawa ua ʻoi aku ka paʻakikī, ʻoiai ʻoe e kau i nā ʻōlelo aʻoaʻo o nā probe i ke kaʻina a ʻaʻole hiki ke hana ʻia i ka like. Inā ʻaʻole like ia, ke koho nei i ka nui kūpono a kau i ka uea ʻulaʻula ma ka pine A.

ʻOi aku ka nui o nā hana a kekahi mau multimita ma mua o ka hana ʻia ma kahi ala like. Hoʻohui ʻia, aia kekahi mau mea e loaʻa a pihi i nā pihi, hoʻomanaʻo, a pēlā aku. Hiki paha iā ʻoe heluhelu i ka manual o kāu k modelkohu no ka ʻike hou aku a e mahalo i nā hana palekana. Hiki i kahi ana maikaʻi ʻole ke hōʻino ʻole i ka multimeter ...

Pehea e koho ai i kahi multimeter

pehea e koho ai i ka multimeter

Inā e noʻonoʻo pehea e koho ai i ka multimeter, pono ʻoe e hoʻomanaʻo i nā pono aʻe:

  • Hoʻoholo a me nā helu: ʻo ka mea mua e koho i waena o ka analog a i ʻole ka uila, e like me kāu makemake, ʻoiai wau e paipai iā ʻoe i ka uila. Ke loaʻa iā ʻoe kēlā maopopo, pono ʻoe e nānā i ka ʻikepili hoʻonā, kahi e hoʻoholo ai i ka loli liʻiliʻi e hiki ai ke ana. ʻO ka maikaʻi ia, ʻoi aku ka maʻalahi o ka maʻalahi.
  • pololei- He mea nui ka pololei o kāu mau mea ana. ʻOi aku inā makemake ʻoe ia no ka hoʻohana ʻoihana a no nā noi kahi e hiki ai i nā hoʻololi liʻiliʻi ke hoʻololi nui. Ana pinepine ʻia kēia i%. ʻO ka helu haʻahaʻa, ʻoi aku ka maikaʻi. ʻO kahi laʻana, hiki paha ± 0.05% + 3 LSD, ʻo ia hoʻi he kikoʻī kāna, ʻo LSD ka helu nui liʻiliʻi e hōʻike ana i ke kikoʻī i hōʻike ʻia e ka hewa i hana ʻia e ka circuitry (halulu, nā ʻae ʻana o ka mea hoʻololi ADC,…). I kēia hihia, inā makemake ʻoe e ana i ka uila me kēlā mau waiwai o kahi hōʻailona 12 VDC, e hōʻike ana kāu multimeter e ana i kahi waiwai ma waena o 11,994 a me 12,006V, kahi e hui pū ai me ka LSD o 3 ka hopena hope i hōʻike ʻia. ma waena o 11,001 a me 12,009 V.
  • RMS (TrueRMS)ʻO kēia kekahi o nā ʻokoʻa nui loa ma waena o ka multimeter nike a me kahi ʻoihana. Kuhi ia i nā ana AC, i ka wā o nā mea hana maʻalahi e manaʻo ʻia he hemolele sinusoidal nā nalu, kahi mea ʻaʻole ia i ka ʻoiaʻiʻo, e hōʻike nei i nā heluhelu heluhelu liʻiliʻi loa. I ka hihia o TrueRMS e hōʻike ia i nā ana kūpono hou aʻe.
  • Hoʻokomo komo- ʻO kēia kekahi mea hoʻokaʻawale nui ma waena o ka maikaʻi a me ka maikaʻi ʻole mai ka maikaʻi. Ke kiʻekiʻe ka impedance i ke komo, e hoʻohuli kēia i ke ana o nā waiwai i hiki ke ana ʻia. Loaʻa i nā kāne maikaʻi ʻole 1MΩ, ʻoiai ka mea maikaʻi hiki ke lilo i 10MΩ a ʻoi paha.
  • oihana: he mea nui e loaʻa iā ʻoe kahi multimeter i loaʻa nā nui āpau āu e pono ai e ana i nā manawa mau. Kekahi i kekahi keu hiʻona i kekahi 'ē aʻe mai. No laila, e hoʻoholo i kāu mea e pono ai i kāu hana maʻamau a i ʻole hoʻokipa, a koho i kahi i loaʻa kēlā mau nui.

Paipai ʻia nā multimita

Inā makemakeʻoe koho i kahi hiʻohiʻona palekana, hiki iā ʻoe ke hoʻohana i kēia papa inoa me kekahi o nā mea ʻoi loa āu e ʻike ai, a me nā kumu kūʻai like ʻole e hoʻopili ai i nā ʻeke a me nā pono āpau.

  • ʻO Fluke 115- He multimeter kikohoʻe ʻoihana TrueRMS, a me kahi hōʻike LCD keʻokeʻo e hana ai i nā wahi mālamalama kiʻekiʻe.
  • Uni-Ball T UT71: kekahi o nā multima ʻoihana ʻoi loa o ka mākeke me kahi hōʻike LCD kikohoʻe. Me ke kūlana kiʻekiʻe a me ka hilinaʻi.
  • Extech EX355: multimeter me TrueRMS, nā ana pololei loa no DC a me AC, LoZ e hōʻalo ai i nā heluhelu wahaheʻe ʻana e nā uila phantom, kānana pass low FPB no ke ana ʻana i nā hōʻailona pinepine pinepine ʻana, ʻike uila uila AC ʻole pili me ka hōʻike LED.
  • Kaiweets HT118A: TrueRMS, kiʻekiʻe kikoʻī, lehulehu o nā hana, autoranging e ana maʻalahi a me ka wikiwiki, he NCV non-contact voltage detector, nā pale no ka palekana nui a me ka paʻa.
  • ʻO Kuman: haʻahaʻa akā hana ka hana. Me TrueRMS, kahi lehulehu o nā hana.
  • ʻAʻohe huahana i loaʻa.Kekahi inexpensive, kikohoʻe hōʻike hoʻāʻo no nā ana he nui. Kūpono no nā mea hoʻomaka a amateurs. Me ka NCV a me ke kī o ka hana.
  • AoKoZo: kekahi o nā mea ʻemi loa, akā ʻaʻole maikaʻi iki. Me NVC, TrueRMS, a me nā hiʻohiʻona āpau āu e manaʻo ai mai ka multimeter uila.
  • Shexton: Inā makemake ʻoe i kahi analog ma waho o ka nostalgia a i ʻole no ka mea makemake ʻoe i kēia ʻano hāmeʻa, loaʻa iā ʻoe ke koho o kēia ʻoihana ʻoi kiʻekiʻe ʻoihana.
  • ʻO Nikou: kekahi ʻano analog ʻē aʻe i ka mea ma mua. Inexpensive, akā hana ia ka hana inā ʻoe e ʻimi ana i kahi mea maʻalahi.

Hoʻopili ka ʻike o ka ʻatikala i kā mākou kumumanaʻo o ka hoʻoponopono hoʻoponopono. E hōʻike i kahi kaomi hemahema ʻaneʻi.
