Alamomin kewayawa na Multimeter da Ma'anarsu
Abubuwa
Ana amfani da multimeter don auna ƙarfin lantarki, juriya, halin yanzu da ci gaba. Yana daya daga cikin kayan aikin wutar lantarki da aka fi amfani dashi. Abu na gaba da za a yi bayan siyan shi ne koyon yadda ake ɗaukar karatu daidai.
Kuna da multimeter na dijital amma ba ku san ta ina za ku fara ba? Kun zo wurin da ya dace. Da fatan za a ci gaba da karantawa don gano duk abin da kuke buƙatar sani game da alamomin kewayawa na multimeter da ma'anarsu.
Alamun Multimeter da kuke buƙatar sani
Alamun multimeter su ne waɗanda za ku samu akan zanen da'ira.
Sun hada da;
1. Alamun Multimeter Voltage
Saboda multimeters suna auna halin yanzu kai tsaye (DC) da alternating current (AC), suna nuna alamar ƙarfin lantarki fiye da ɗaya. Naɗin wutar lantarki na AC don tsofaffin multimeters shine VAC. Masu kera suna sanya layin igiya sama da V don sabbin samfura don nuna wutar lantarki ta AC.
Don wutar lantarki na DC, masana'antun suna sanya layin dige-dige tare da tsayayyen layi a samansa sama da V. Idan kuna son auna ƙarfin lantarki a cikin millivolts, watau 1/1000 na volt, kunna bugun kira zuwa mV.
2. Juriya alamomin multimeter
Wata alamar kewayawa multimeter da ya kamata ku sani ita ce juriya. A multimeter yana aika ƙaramin lantarki ta hanyar da'ira don auna juriya. Harafin Helenanci Omega (Ohm) alama ce ta juriya akan multimeter. Ba za ku ga kowane layi sama da alamar juriya ba saboda mita ba sa bambanta tsakanin juriyar AC da DC. (1)
3. Alamar multimeter na yanzu
Kuna auna halin yanzu kamar yadda kuke auna ƙarfin lantarki. Yana iya zama alternating current (AC) ko kai tsaye (DC). Lura cewa ampere ko ampere raka'a ne na halin yanzu, wanda ke bayyana dalilin da yasa alamar multimeter don halin yanzu shine A.
Duban multimeter a yanzu, za ku ga harafin "A" tare da layi mai laushi a sama da shi. Wannan shine alternating current (AC). Harafin "A" tare da layi biyu-dashe kuma mai ƙarfi a samansa-yana wakiltar kai tsaye (DC). Lokacin auna halin yanzu tare da multimeter, zaɓin da ake samu shine mA don milliamps da µA don microamps.
Jacks da maɓalli
Kowane DMM yana zuwa da jagora biyu, baki da ja. Kada ka yi mamaki idan multimeter naka yana da haši uku ko hudu. Duk abin da kuka gwada yana ƙayyade inda kuka haɗa wayoyi.
Ga amfanin kowanne;
- cOM - jack gama gari baki ɗaya ne kawai. Anan bakar gubar ta dosa.
- A - Anan ne zaka haɗa jajayen waya lokacin auna halin yanzu har zuwa amperes 10.
- mA - Kuna amfani da wannan soket lokacin auna halin yanzu mai mahimmanci ƙasa da amp lokacin da multimeter yana da kwasfa huɗu.
- mAOm - Socket ɗin auna ya haɗa da ƙarfin lantarki, zafin jiki da ma'anar halin yanzu idan multimeter ɗin ku ya zo da kwasfa uku.
- VOm - Wannan don duk sauran ma'auni ne banda halin yanzu.
Sanin multimeter ɗin ku, musamman saman nunin multimeter. Kuna ganin maɓalli biyu - ɗaya a dama da ɗaya a hagu?
- Motsi – Domin adana sarari, masana'anta na iya sanya ayyuka biyu zuwa wasu wurare na bugun kira. Don samun damar aikin da aka yiwa alama a rawaya, danna maɓallin Shift. Maɓallin Shift mai launin rawaya na iya ko ba shi da lakabin. (2)
- Ci gaba - danna maɓallin riƙewa idan kuna son daskare karatun na yanzu don amfani daga baya.
Don taƙaita
Kada ku sami matsala don samun ingantaccen karatun DMM. Muna fatan cewa bayan karanta wannan bayanin mai amfani, kuna jin kun saba da alamomin multimeter.
Dubi wasu labaran mu a kasa.
- Teburin alamar Multimeter
- Alamar capacitance Multimeter
- Alamar wutar lantarki ta Multimeter
