Nā Hōʻailona Kaapuni Multimeter a me ko lākou mau manaʻo
Nā mea
Hoʻohana ʻia ka multimeter e ana i ka volta, ke kūpaʻa, ka manawa a me ka hoʻomau. ʻO ia kekahi o nā mea hana mana maʻamau. ʻO ka mea aʻe e hana ai ma hope o ke kūʻai ʻana, ʻo ia ke aʻo ʻana i ka lawe pono ʻana i nā heluhelu.
Loaʻa iā ʻoe kahi multimeter kikohoʻe akā ʻaʻole maopopo i kahi e hoʻomaka ai? Ua hele mai ʻoe i kahi kūpono. E ʻoluʻolu e heluhelu e ʻike i nā mea a pau e pono ai ʻoe e ʻike e pili ana i nā hōʻailona kaapuni multimeter a me ko lākou mau manaʻo.
Nā hōʻailona multimeter pono ʻoe e ʻike
ʻO nā hōʻailona multimeter nā mea āu e ʻike ai ma ke kiʻi kaapuni.
Aia lākou;
1. Nā hōʻailona multimeter Voltage
Ma muli o ke ana ʻana o nā multimeters i ke au pololei (DC) a me ka volternating current (AC), hōʻike lākou i nā hōʻailona ʻoi aku ma mua o hoʻokahi. ʻO ka koho ʻana o ka volta AC no nā multimeter kahiko ʻo VAC. Hoʻokomo nā mea hana i kahi laina wavy ma luna o ka V no nā hiʻohiʻona hou e hōʻike i ka volta AC.
No ka uila DC, kau nā mea hana i kahi laina kiko me kahi laina paʻa ma luna o ia ma luna o V. Inā makemake ʻoe e ana i ka volta i millivolts, ʻo ia hoʻi 1/1000 o kahi volt, e hoʻohuli i ke kelepona i mV.
2. Nā hōʻailona multimeter kū'ē
ʻO kekahi hōʻailona kaapuni multimeter pono ʻoe e ʻike kūʻē. Hoʻouna ka multimeter i kahi au uila liʻiliʻi ma o ke kaapuni e ana i ke kū'ē. ʻO ka leka Helene Omega (Ohm) ka hōʻailona no ke kū'ē ma kahi multimeter. ʻAʻole ʻoe e ʻike i nā laina ma luna o ka hōʻailona kū'ē no ka mea ʻaʻole ʻike nā mika ma waena o ke kūpaʻa AC a me DC.

3. Hōʻailona multimeter o kēia manawa
Ana ʻoe i kēia manawa e like me ke ana ʻana i ka volta. Hiki ke hoʻololi i kēia manawa (AC) a i ʻole ke au pololei (DC). E hoʻomanaʻo ʻo ampere a i ʻole ampere nā ʻāpana o kēia manawa, e wehewehe ana i ke kumu ʻo A ka hōʻailona multimeter no kēia manawa.
Ke nānā nei ʻoe i ka multimeter i kēia manawa, e ʻike ʻoe i ka huaʻōlelo "A" me kahi laina wavy ma luna. ʻO kēia ka ʻāwili ʻana (AC). ʻO ka huapalapala "A" me nā laina ʻelua—kaomi a paʻa ma luna o ia—e hōʻike ana i ke au pololei (DC). Ke ana ʻana i kēia manawa me kahi multimeter, ʻo nā koho i loaʻa he mA no nā milliamps a me µA no nā microamps.
Nā kī a me nā pihi
Hele mai kēlā me kēia DMM me ʻelua mau alakaʻi, ʻeleʻele a me ka ʻulaʻula. Mai kahaha inā ʻekolu a ʻehā mau mea hoʻohui i kāu multimeter. ʻO nā mea āu e hoʻāʻo ai e hoʻoholo i kahi āu e hoʻopili ai i nā uea.
Eia ka hoʻohana ʻana o kēlā me kēia;
- mail – hoʻokahi wale nō ʻeleʻele ka jack maʻamau. Ma laila ke alakaʻi ʻeleʻele e hele ai.
- A - ʻO kēia kahi āu e hoʻopili ai i ke kelepona ʻulaʻula ke ana ʻana i kēia manawa a hiki i 10 amperes.
- mAmkA – Hoʻohana ʻoe i kēia kumu i ke ana ʻana i ke au koʻikoʻi ma mua o ka amp inā ʻehā kumu o ka multimeter.
- mAOm - Aia i loko o ke kumu ana ka volta, ka mahana a me ka manaʻo o kēia manawa inā hele mai kāu multimeter me ʻekolu kumu.
- VOm – No nā ana ʻē aʻe a pau koe wale nō kēia.
E ʻike i kāu multimeter, ʻoi aku ka luna o ka hōʻike multimeter. ʻIke ʻoe i ʻelua pihi - hoʻokahi ma ka ʻākau a me kekahi ma ka hema?
- Shift - I mea e mālama ai i ka lewa, hiki i nā mea hana ke hāʻawi i ʻelua mau hana i kekahi mau kūlana kelepona. No ke komo ʻana i ka hana i kaha ʻia me ka melemele, e kaomi i ke pihi Shift. He lepili paha ka pihi Shift melemele. (2)
- Mālama - kaomi i ke pihi paʻa inā makemake ʻoe e hoʻokuʻu i ka heluhelu o kēia manawa no ka hoʻohana ʻana ma hope.
E hōʻuluʻulu
ʻAʻohe pilikia e loaʻa iā ʻoe nā heluhelu DMM pololei. Lana ko mākou manaʻo ma hope o ka heluhelu ʻana i kēia ʻike pono, ua kamaʻāina ʻoe i nā hōʻailona multimeter.
E nānā i kekahi o kā mākou ʻatikala ma lalo nei.
- Pākaukau hōʻailona multimeter
- Hōʻailona capacitance multimeter
- ʻO ka hōʻailona uila uila
