Yadda Ake Gwaji Ground Da Multimeter (Jagorancin Mataki na 6)

Ga kowane tsarin wayoyi na lantarki, kasancewar wayar ƙasa yana da mahimmanci. Wani lokaci rashin waya ta ƙasa na iya haifar da mummunan sakamako ga dukan kewaye. Abin da ya sa a yau za mu dubi yadda za a duba ƙasa tare da multimeter.

A matsayinka na mai mulki, bayan saita multimeter zuwa matsakaicin ƙarfin lantarki, zaka iya shigar da gwajin gwaji don duba zafi, tsaka-tsaki da ƙananan igiyoyi da ƙarfin su. Sa'an nan za ku iya tantance ko an kafa hanyar da kyau ko a'a. A ƙasa za mu zurfafa cikin wannan.

Menene grounding?

Kafin mu fara aikin gwaji, muna buƙatar tattaunawa game da ƙasa. Idan ba tare da ingantaccen fahimtar ƙasa ba, ci gaba ba shi da ma'ana. Don haka a nan akwai bayani mai sauƙi na ƙasa.

Babban manufar haɗin ƙasa shine don canja wurin da aka fitar da wutar lantarki daga na'ura ko fitarwa zuwa ƙasa. Saboda haka, babu wanda zai sami girgizar wutar lantarki saboda fitar da wutar lantarki. Ingantacciyar ƙa'idar aminci wacce ke da filin aiki na buƙatar waya. Kuna iya amfani da wannan tsari don gidanku ko motarku. (1)

Jagoran Mataki na 6 don Gwaji Wayar Ƙasa tare da Multimeter

A cikin wannan sashe, za mu tattauna yadda za a gwada ƙasa tare da multimeter. Hakanan, don wannan demo, za mu yi amfani da fitilun lantarki na gida na yau da kullun. Manufar ita ce a gano ko an kafa tashar da kyau. (2)

Mataki 1 - Saita multimeter

Da farko, dole ne ka saita multimeter da kyau don tsarin gwaji. Don haka, saita multimeter ɗin ku zuwa yanayin ƙarfin lantarki na AC. Koyaya, idan kuna amfani da multimeter analog, dole ne ku saita bugun kiran zuwa matsayin V.

A gefe guda, idan kuna amfani da DMM, dole ne ku sake zagayowar ta hanyar saitunan har sai kun sami wutar lantarki ta AC. Da zarar ka samo shi, saita ƙimar yanke zuwa mafi girman ƙarfin lantarki. Ka tuna, saita ƙarfin lantarki zuwa mafi girman saiti zai taimaka maka sosai wajen samun ingantaccen karatu.

Koyaya, ana jigilar wasu na'urori masu yawa ba tare da ƙimar yankewa ba. A wannan yanayin, saita multimeter zuwa saitunan wutar lantarki na AC kuma fara gwaji.

Mataki na 2 - Haɗa na'urori masu auna firikwensin

Multimeter yana da bincike guda biyu masu launi daban-daban, ja da baki. Dole ne a haɗa waɗannan binciken guda biyu yadda ya kamata zuwa tashar jiragen ruwa na multimeter. Don haka, haɗa jagorar gwajin ja zuwa tashar jiragen ruwa mai alamar V, Ω, ko +. Sannan haɗa binciken baƙar fata zuwa tashar jiragen ruwa mai alamar - ko COM. Haɗin da ba daidai ba na waɗannan binciken biyu da tashoshin jiragen ruwa na iya haifar da ɗan gajeren da'ira a cikin multimeter.

Hakanan, kar a yi amfani da na'urori masu auna firikwensin da suka lalace ko fashe. Hakanan, guje wa amfani da bincike tare da wayoyi maras amfani saboda kuna iya samun girgiza yayin gwaji.

Mataki na 3 - Duba Karatu Ta Amfani da Tashoshi masu Aiki da Tsaki

Yanzu zaku iya duba waya ta ƙasa tare da multimeter. A wannan gaba, yakamata ku gwada wayoyi masu zafi da tsaka tsaki tare da gwajin gwajin multimeter.

Kafin yin wannan, tabbatar da riƙe da binciken daga abin rufe fuska, wannan zai kare ku daga kowane tasiri.

Sannan saka jan binciken a cikin tashar tashar aiki.

Ɗauki binciken baƙar fata kuma saka shi cikin tashar tsaka tsaki. Yawanci, ƙaramar tashar jiragen ruwa ita ce tashar jiragen ruwa mai aiki kuma babbar tashar jiragen ruwa ita ce tashar tsaka-tsaki.

“Duk da haka, idan ba za ku iya gano tashar jiragen ruwa ba, koyaushe kuna iya amfani da hanyar gargajiya. Fito da wayoyi guda uku, sannan tare da launuka daban-daban, zaku iya fahimtar wayoyi cikin sauki.

Yawanci waya mai rai tana launin ruwan kasa, wayar tsaka-tsakin kuma shudi ne, kuma wayar kasa rawaya ce ko kore.”

Bayan shigar da bincike guda biyu a cikin tashar jiragen ruwa masu rai da tsaka tsaki, duba ƙarfin lantarki akan multimeter kuma yi rikodin shi.

Mataki na 4 - Duba wutar lantarki ta amfani da tashar tashar ƙasa

Ya kamata a yanzu duba ƙarfin lantarki tsakanin tashar jiragen ruwa masu rai da ƙasa. Don yin wannan, cire gubar gwajin ja daga tashar tsaka tsaki kuma a hankali saka shi cikin tashar ƙasa. Kar a cire haɗin binciken baƙar fata daga tashar jiragen ruwa mai aiki yayin wannan aikin. Tashar ruwa ta ƙasa rami ne mai zagaye ko U-dimbin yawa wanda yake a ƙasa ko saman mashigar.

Duba karatun ƙarfin lantarki akan multimeter kuma rubuta shi. Yanzu kwatanta wannan karatun da karatun baya.

Idan hanyar haɗin yanar gizon ta kasance ƙasa, za ku sami karatun da yake a ko tsakanin 5V. Duk da haka, idan karatun tsakanin tashar tashar jiragen ruwa da ƙasa ya kasance sifili ko kusa da sifili, wannan yana nufin fitarwar ba ta da tushe.

Mataki na 5 - Kwatanta Duk Karatun

Kuna buƙatar aƙalla karatu uku don kwatancen da ya dace. Kun riga kuna da karatu guda biyu.

Fara karatu: Karatu kai tsaye da tashar tashar tsaka tsaki

Karatu na biyu: Tashar tashar jiragen ruwa na ainihi da karatun ƙasa

Yanzu ɗauki karatu daga tashar tsaka tsaki da tashar ƙasa. Yi shi:

1. Saka binciken ja a cikin tashar tsaka tsaki.
2. Saka binciken baƙar fata a cikin tashar tashar ƙasa.
3. Rubuta karatun.

Za ku sami ƙaramin ƙima don waɗannan tashoshin jiragen ruwa biyu. Duk da haka, idan haɗin da gidan ba a kasa ba, babu buƙatar karatu na uku.

Mataki na 6 - Ƙididdige yawan zubewar

Idan kun kammala matakai na 3,4, 5 da XNUMX, yanzu kuna da karatu daban-daban guda uku. Daga waɗannan karatun guda uku, ƙididdige jimillar yayyo.

Don nemo jimlar ɗigon, cire karatun farko daga na biyu. Sannan ƙara karatu na uku zuwa sakamakon karatun. Idan sakamakon ƙarshe ya fi 2V, ƙila kuna aiki tare da wayar ƙasa mara kyau. Idan sakamakon bai wuce 2V ba, soket ɗin yana da aminci don amfani.

Wannan babbar hanya ce don nemo wayoyin ƙasa mara kyau.

Matsalolin ƙasan lantarki na mota

Ga kowace mota, ana iya samun wasu matsalolin lantarki saboda rashin ƙarancin ƙasa. Bugu da ƙari, waɗannan matsalolin na iya bayyana ta nau'i-nau'i da yawa, kamar surutu a cikin tsarin sauti, matsaloli tare da famfo mai, ko rashin aiki na sarrafa injin lantarki. Idan za ku iya guje wa waɗannan matsalolin, zai yi kyau a gare ku da motar ku.

Ga wasu shawarwari kan yadda za a hana irin wannan yanayin.

Matsayin ingancin ƙasa

Yawancinmu muna tunanin cewa idan ko ta yaya wayar ƙasa ta haɗu da motar, komai yana ƙasa. Amma wannan ba gaskiya ba ne. Dole ne a haɗa waya ta ƙasa da kyau da abin hawa. Misali, zaɓi wurin da ba shi da fenti da tsatsa. Sai ka haɗa.

Yi amfani da multimeter don bincika ƙasa

Bayan haɗa wayar ƙasa, koyaushe yana da kyau a duba ƙasa. Don haka, yi amfani da multimeter don wannan tsari. Yi amfani da baturi da wayar ƙasa don tantance ƙarfin lantarki.

Yi amfani da manyan wayoyi

Dangane da ƙarfin halin yanzu, kuna iya buƙatar canza girman waya ta ƙasa. Yawanci, wayoyi na masana'anta sune ma'auni 10 zuwa 12.

A ƙasa akwai wasu jagororin horo na multimeter waɗanda kuma zaku iya dubawa.

• Yadda ake amfani da multimeter don duba wutar lantarki na wayoyi masu rai
• Yadda za a ƙayyade waya mai tsaka tsaki tare da multimeter
• Yadda ake Amfani da Multimeter Digital Cen-Tech don Duba Wutar Lantarki
