Menene multimeter?
Multimeter shine ainihin kayan aunawa wanda zai iya auna halaye daban-daban na lantarki kamar ƙarfin lantarki, juriya, da halin yanzu. Hakanan ana kiran na'urar da volt-ohm-millimeter (VOM) saboda tana aiki azaman voltmeter, ammeter, da ohmmeter.
Nau'in multimeters
Waɗannan na'urori masu aunawa sun bambanta da girma, fasali da farashi kuma an ƙera su don ɗauka ko amfani da su akan tebur dangane da amfanin da aka yi niyya. Nau'in multimeters sun haɗa da:
- Analog multimeter (koyi yadda ake karantawa a nan)
- Mita da yawa na dijital
- Matsakaicin multimeter
- Matsa multimeter
- Multimeter ta atomatik
Multimeter na ɗaya daga cikin kayan aunawa da aka fi amfani dashi a zamanin yau. Duk da haka, masu farawa sau da yawa suna da wahalar gano alamomi akan multimeter. A cikin wannan labarin, za mu nuna muku yadda ake gane haruffa akan multimeter.
Ko da yake ana samun nau'ikan na'urori daban-daban a kasuwa, duk suna amfani da tsarin alama iri ɗaya. Ana iya raba alamomi zuwa sassa masu zuwa:
- Ikon Kunnawa/Kashe
- ikon gate
- Alamar wutar lantarki
- Alamar yanzu
- Alamar adawa
Ma'anar alamomin akan multimeter
Alamomin da ke cikin multimeter sun haɗa da:
| Alamar | Ayyukan tsarin |
| Maɓallin KYAUTA | Yana taimakawa don yin rikodi da adana bayanan da aka auna. |
| Maɓallin kunnawa / kashewa | Bude, kashe shi. |
| COM tashar jiragen ruwa | Yana tsaye ga Common kuma kusan koyaushe ana haɗa shi da ƙasa (Ground) ko cathode na kewaye. Tashar tashar COM yawanci baƙar fata ce kuma galibi ana haɗa ta da baƙar fata bincike. |
| tashar jiragen ruwa 10 A | Wannan tashar tashar jiragen ruwa ce ta musamman, galibi an tsara ta don auna manyan igiyoyin ruwa (> 200 mA). |
| mA, μA | Ƙananan tashar aunawa na yanzu. |
| mA ohm port | Wannan ita ce tashar jiragen ruwa da ake yawan haɗa jajayen binciken. Wannan tashar jiragen ruwa na iya auna halin yanzu (har zuwa 200mA), ƙarfin lantarki (V), da juriya (Ω). |
| tashar oCVΩHz | Wannan ita ce tashar jiragen ruwa da aka haɗa da jan gubar gwajin. Yana ba ku damar auna zafin jiki (C), ƙarfin lantarki (V), juriya (), mita (Hz). |
| Gaskiya tashar tashar RMS | Yawancin lokaci ana haɗa su da jan waya. Don auna tushen gaskiya yana nufin murabba'i (RMS na gaskiya). |
| Zaɓi maɓallin | Yana taimakawa don canzawa tsakanin ayyuka. |
| haske | Daidaita hasken nunin. |
| Mais ƙarfin lantarki | Madadin halin yanzu. Wasu samfuran ana kiransu kawai A. |
| DC ƙarfin lantarki | D.C. |
| Hz | Auna mitar. |
| DUTY | Zagayen aunawa. Auna capacitance na yanzu. Duba ci gaba, gajeriyar kewayawa (Duba ci gaba). |
| maɓallin sigina | Gwajin Diode (Gwajin Diode) |
| hFE | Gwajin transistor-transistor |
| NCV | Ayyukan shigar da ba na lamba ba |
| Maɓallin REL (dangi) | Saita ƙimar tunani. Yana taimakawa wajen kwatantawa da tabbatar da ma'auni daban-daban. |
| Maɓallin RANGE | Zaɓi yankin ma'aunin da ya dace. |
| MAX/MIN | Ajiye matsakaicin matsakaicin ƙimar shigarwa; Sanarwar ƙararrawa lokacin da aka auna ƙimar ta wuce ƙimar da aka adana. Sannan an sake rubuta wannan sabuwar ƙima. |
| Alamar Hz | Yana nuna mitar kewayawa ko na'ura. |
Yadda ake amfani da multimeter?
- Ana amfani da shi don auna ƙarfin lantarki, misali: auna DC current, AC current.
- Auna juriya tare da wutar lantarki akai-akai, halin yanzu da ƙaramin ohmmeter.
- An yi amfani da shi don auna lokaci da mita cikin sauri. (1)
- Iya tantance matsalolin da'ira na lantarki a cikin motoci, duba batura, masu canza mota, da sauransu. (2)
Wannan labarin yana ba da duk ma'anar alama don tunani don gane duk alamomin da aka nuna akan multimeter. Idan muka rasa ɗaya ko muna da shawara, jin daɗin aiko mana da imel.
