Wani Multimeter?

Maimaita ce?

Maimaita (MM) yana da muhimmanci wajen mutanen da suka yi aiki a cikin ilimin kasa ko kasa na kusurwa. Yana cikin alatun mai karatu da take gudanar da adadin karatu a kan waɗanda, kuma ta shafi zuwa masu aiki, tafiti, da kuma masu shirya abin da suke yi baki ɗaya. Wannan makaltaccen zai tuntubi masu maimaita, irin maimaita, da ke amfani don haka bayan da zai amsa wasu tambayar masu ma'ana game da wannan alatun mai mahimmanci.

Maimaita suna cikin biyu irin da dama: digital (DMMs) da analog. DMMs suna da rufin digital, wanda ya ba su karfi a karamin karatu da kuma bayyana masu kasa na kusurwa da inganci. Amma, analog meters suna amfani da saka a kan dial don nuna darajar da aka bayyana. Idan DMMs suna fi yawa saboda karfin da kuma karfi ga amfani, analog MMs suna iya kasance mai karfi wajen nuna yanayi ko wahalar da aka bayyana.

Daga cikin abubuwan da maimaita ke da, babban muhimman shi shine bayyana volts. Bayyanar volts zai iya samun a cikin alternating current (AC) da direct current (DC) sources. Don haka, maimaita zai haɓaka da circuit da aka fara bayyana ne a taka red da black test probes. Saboda haka, zai iya zama muhimmanci a zaba hanyar bayyana daɗi da kuma duba hukumar da ake amfani a kan volts masu ƙarin.

Wadanda volt, maimaita suna iya bayyana current da resistance. Bayyanar current yana nufin haɓaka da maimaita a series da circuit da aka fara bayyana, amma bayyanar resistance yana nufin haɓaka da maimaita across the component or circuit. Wasu maimaita suna iya bayyana abubuwan da dama, kamar capacitance da frequency, wanda yake tsara karfin da suke yi baki ɗaya.

Maimaita suna da funktar continuity test, wanda yana da muhimmanci wajen duba idan an haɓaka da electrical connection daɗi a kan biyu points a cikin circuit. Wannan funktar yana amfani da tushen current daɗi a kan circuit da kuma duba idan current yana haɓaka biliyan.

Zaɓin maimaita suna da shugaban input resistance, wanda yana nufin yadda za'a iya kawo matsalolin circuit da aka fara bayyana. Saboda haka, ƙarin input resistance yana da muhimmanci, domin ta ci gaba da tashin za a yi a kan circuit. Field-effect transistors (FET) da vacuum-tube voltmeters (VTVMs) suna samun ƙarin input resistance tare da amplifying a tiny current kafin a nuna ita a kan meter.

Zaɓe maimaita da ya danganta da ke bukata yana da muhimmanci a cikin abubuwan da ke bukata, zuwa ingancin bayyana, da kuma bugada. Auto-ranging maimaita suna zaba hanyar bayyana daɗi a kan quantity da aka fara bayyana, kuma suna da karfi ga amfani da manual-ranging maimaita.

Dubawa suna da muhimmanci har sai a amfani da maimaita. Wadannan sun hada da amfani da hanyar bayyana daɗi, koyar da circuits masu haye, da kuma amfani da insulated test probes. Da ɗaya, proper maintenance da calibration of the multimeter suna da muhimmanci don bayyana inganci har sai lokacin lafiya.

Maimaita yana da karfi ga amfani, yana cikin alatun mai karatu da take gudanar da adadin karatu a kan waɗanda, kuma ta shafi zuwa masu aiki, tafiti, da kuma masu shirya abin da suke yi baki ɗaya. Tushen bayyana voltage, current, resistance, da kuma abubuwan da dama a cikin variety power supply applications. Ta haka da fahimtar farkon analog da digital maimaita, abubuwan da suke yi baki ɗaya, da kuma muhimmancin dubawa, masu amfani zai iya samun hankali wajen zabe maimaita da ya danganta da ke bukata.

Bayanin: Rabta don asalin, makaloli mai kyau za su iya shari, idandaza akwai infingement zaka so in tabbatar da in share.
