Pākaukau hōʻailona multimeter: wehewehe
Nā mea
He aha ka multimeter?
ʻO ka multimeter kahi mea hana maʻamau e ana i nā ʻano uila like ʻole e like me ka volta, ke kūpaʻa, a me ke au. Ua ʻike ʻia ka mea hana he volt-ohm-millimeter (VOM) no ka mea he voltmeter, ammeter, a me ohmmeter.
Nā ʻano multimeter
ʻOkoʻa kēia mau mea ana i ka nui, nā hiʻohiʻona a me nā kumukūʻai a ua hoʻolālā ʻia e lawe ʻia a hoʻohana ʻia paha ma ka papaʻaina ma muli o kā lākou hoʻohana ʻana. Aia nā ʻano multimeters:
- Analog multimeter (aʻo pehea e heluhelu ai maanei)
- Multimeter mīkini
- ʻO ka multimeter fluke
- Hoʻopili multimeter
- Multimeter ʻakomi
ʻO ka multimeter kekahi o nā mea ana maʻamau i kēia mau lā. Eia naʻe, paʻakikī pinepine ka poʻe hoʻomaka e ʻike i nā hōʻailona ma kahi multimeter. Ma kēia ʻatikala, e hōʻike mākou iā ʻoe pehea e ʻike ai i nā huaʻōlelo ma kahi multimeter.
ʻOiai aia nā ʻano multimeters like ʻole ma ka mākeke, hoʻohana lākou a pau i ka ʻōnaehana hōʻailona like. Hiki ke hoʻokaʻawale ʻia nā hōʻailona i kēia mau ʻāpana:
- Ikona On/Ope
- ikona puka
- Hōʻailona Voltage
- Hōʻailona o kēia manawa
- Hōʻailona pale
ʻO ke ʻano o nā hōʻailona ma ka multimeter
Aia nā hōʻailona ma ka multimeter:
| Hōʻailona | Hana ʻōnaehana |
| pihi HOLD | Kōkua ia i ka hoʻopaʻa ʻana a mālama i ka ʻikepili i ana ʻia. |
| Pākuʻi hoʻopaʻa | E wehe, e hoopau. |
| Awa COM | Kū ia no Common a aneane pili mau i ka honua (Ground) a i ʻole cathode o ke kaapuni. ʻEleʻele ka waihoʻoluʻu o ke awa COM a pili pū kekahi me ka ʻeleʻele ʻeleʻele. |
| awa 10A | He awa kūikawā kēia, i hana pinepine ʻia e ana i nā au kiʻekiʻe (> 200 mA). |
| mA, μA | awa ana haahaa o keia manawa. |
| awa mA ohm | ʻO kēia ke awa e hoʻopili pinepine ʻia ai ka ʻimi ʻulaʻula. Hiki i kēia awa ke ana i kēia manawa (a hiki i ka 200mA), ka uila (V), a me ke kū'ē (Ω). |
| awa oCVΩHz | ʻO kēia ke awa i hoʻopili ʻia i ke alakaʻi hoʻāʻo ʻulaʻula. ʻAe iā ʻoe e ana i ka mahana (C), ka uila (V), ke kū'ē (), ke alapine (Hz). |
| awa RMS maoli | Hoʻohui maʻamau i ka uwea ʻulaʻula. No ke ana ʻana i ke kumu ʻoiaʻiʻo mean square (true RMS) parameter. |
| Pihi koho | Kōkua ia e hoʻololi i waena o nā hana. |
| ʻōlinolino | Hoʻoponopono i ka ʻōlinolino o ka hōʻike. |
| Volta uila | ʻAuhea ʻokoʻa. ʻO kekahi mau huahana i kapa ʻia ʻo A. |
| Voli uila DC | ʻO D.C. |
| Hz | E ana i ke alapine. |
| KEKAHI | ʻAna pōʻaiapuni. E ana i ka capacitance o kēia manawa. E nānā i ka hoʻomau, ka pōkole pōkole (Continuity check). |
| pihi hōʻailona | Ho'āʻo Diode (Hoʻāʻo Diode) |
| hFE | Hoʻāʻo transistor-transistor |
| NCV | ʻO ka hana induction o kēia manawa non-contact |
| Pihi REL (pili) | E hoʻonoho i ka waiwai kuhikuhi. Kōkua i ka hoʻohālikelike a hōʻoia i nā waiwai i ana ʻia. |
| pihi RANGE | E koho i kahi ana kūpono. |
| MAX / MIN | E mālama i ka nui a me ka liʻiliʻi o ka hoʻokomo waiwai; Hoʻolaha beep ke ʻoi aku ka waiwai i ana ʻia ma mua o ka waiwai i mālama ʻia. A laila ua pani ʻia kēia waiwai hou. |
| Hōʻailona Hz | Hōʻike i ke alapine o kahi kaapuni a mea hana paha. |
Ke hoʻohana nei i ka multimeter?
- Hoʻohana ʻia no ke ana ʻana i ka volta, no ka laʻana: ana i kēia manawa DC, ʻĀpana AC.
- E ana i ke kū'ē me ka volta mau, ke au a me ka ohmmeter liʻiliʻi.
- Hoʻohana ʻia e ana wikiwiki i ka manawa a me ka pinepine. (1)
- Hiki iā ʻoe ke ʻike i nā pilikia kaapuni uila i nā kaʻa, nānā i nā pila, nā mea hoʻololi kaʻa, etc. (2)
Hāʻawi kēia ʻatikala i nā wehewehe hōʻailona āpau no ka ʻike ʻana i nā hōʻailona āpau i hōʻike ʻia ma ka multimeter. Inā haʻalele mākou i kekahi a i ʻole he manaʻo, e ʻoluʻolu e leka uila iā mākou.
