Yadda ake gwada ƙasa da multimeter
Abubuwa
Fitilar fitilun ku na kyalli? Shin injin wanki yana jinkiri, yana aiki mara kyau, ko baya aiki kwata-kwata?
Idan amsar ku ga waɗannan tambayoyin eh, to haɗin ƙasa a cikin gidanku mai yiwuwa ne.
Yin ƙasa a cikin gidanku yana ɗaya daga cikin mahimman abubuwan da kuke buƙatar kulawa.
Yin aiki da kyau na na'urorin lantarki ba kawai mahimmanci bane, amma yana iya zama bambanci tsakanin rayuwa da mutuwa.
A cikin wannan jagorar, zaku sami duk abin da kuke buƙatar sani game da wurin gwajin.
Mu fara.
Menene grounding?
Grounding, wanda kuma ake kira grounding, wani abu ne na kariya a cikin haɗin lantarki wanda ke rage haɗari ko sakamakon girgiza wutar lantarki.
Tare da shimfidar ƙasa mai kyau, wutar lantarki da ke fitowa daga kantuna ko na'urorin lantarki ana tura su zuwa ƙasa, inda ta bace.
Ba tare da saukar da ƙasa ba, wannan wutar lantarki tana haɓakawa a cikin kantuna ko sassan ƙarfe na na'urar kuma yana iya haifar da na'urori ba su aiki ko aiki yadda yakamata.
Mutumin da ya yi mu'amala da waɗannan abubuwan ƙarfe masu cajin lantarki ko wayoyi da aka fallasa yana cikin haɗarin girgiza wutar lantarki.

Kayan na'urorin ku suna aiki akan alternating current (AC) kuma kamar yadda aka zata, wannan shine nau'in wutar lantarki da aka fitar.
Yanzu kawai kuna juya bugun kiran multimeter zuwa saitunan wutar lantarki na AC, wanda aka fi sani da "VAC" ko "V~".
Wannan yana ba ku ingantaccen karatu.
- Mataki na 3: Auna wutar lantarki tsakanin tashoshin aiki da tsaka tsaki
Sanya jagorar gwajin ja (tabbatacce) na multimeter a cikin tashar fitarwa mai kuzari da baƙar (mara kyau) jagorar gwajin cikin tashar tsaka tsaki.
Tashar jiragen ruwa mai aiki yawanci ita ce ƙarami na tashoshin jiragen ruwa guda biyu a kan kanti, yayin da tashar tsaka tsaki ita ce mafi tsayi daga cikin biyun.
Tashar jiragen ruwa, a daya bangaren, yawanci ana siffanta su kamar "U".
Tashar jiragen ruwa a kan wasu kantunan bango za a iya siffata daban-daban, a cikin wannan yanayin tashar tashar aiki yawanci tana kan dama, tashar tsaka tsaki tana gefen hagu, tashar tashar ƙasa tana saman.
Karatun wutar lantarki tsakanin wayar ku mai rai da tsaka tsaki yana da mahimmanci don kwatancen da za a yi daga baya.
Ɗauki ma'aunin ku kuma matsa zuwa mataki na gaba.
- Mataki na 4: Auna wutar lantarki tsakanin tashar jiragen ruwa masu rai da ƙasa
Yanzu cire binciken ku na baƙar fata daga tashar fitarwa mai tsaka-tsaki kuma toshe shi cikin tashar ƙasa.
Lura cewa jan bincikenku ya rage a tashar tashar aiki.
Hakanan zaku tabbatar cewa binciken yana yin hulɗa tare da abubuwan ƙarfe a cikin kwasfa don multimeter ɗinku ya sami karatu.

Wannan yana nufin cewa a gaban ƙasa, idan gwajin lokaci da tsaka tsaki ya gano 120V, ana sa ran gwajin lokaci da ƙasa don gano 115V zuwa 125V.
- Kawai idan duk wannan ya tabbata, zaku yi ƙarin kwatance. Wannan wajibi ne don duba matakin yabo daga ƙasa kuma ƙayyade ingancinsa.
Samu bambanci tsakanin gwajin rayuwa da tsaka tsaki da gwajin rayuwa da ƙasa.
Ƙara wannan zuwa tsaka tsaki da karatun gwajin ƙasa.
Idan ƙarin su ya wuce 2V, to haɗin ƙasa ba ya cikin cikakkiyar yanayin kuma ya kamata a bincika.
A cikin wannan bidiyon mun bayyana dukkan tsarin:
Wani gwajin da zaku iya yi shine game da juriya na ƙasa na haɗin ku da ƙasa.
Koyaya, wannan batu ne mabanbanta, kuma zaku iya bincika cikakken labarinmu akan juriya na ƙasa tare da multimeter.
Wurin gwajin kwan fitila
Don duba ƙasa a tashar gidan ku tare da kwan fitila, kuna buƙatar soket ɗin ƙwallon ƙafa da igiyoyi biyu.
Matsa a cikin kwan fitila sannan kuma haɗa igiyoyin zuwa soket ɗin ƙwallon.
Yanzu tabbatar da sauran ƙarshen igiyoyin aƙalla 3cm ba komai (babu rufi) kuma toshe su cikin tashar fitarwa mai rai da tsaka tsaki.
Idan hasken bai kunna ba, to gidanku bai yi kasa sosai ba.
Kamar yadda kuke gani, wannan gwajin bai cika daki-daki ba kuma ba daidai ba kamar gwajin tare da multimeter.

Ta yaya za ku san idan kuna da mummunar waya ta ƙasa?
Alama ɗaya ta gama gari na rashin ƙasa a gidaje shine fitillu ko fitillu. A wasu lokuta, na'urorin lantarki a cikin gidanka bazai kunna ba ko kuma bazai yi aiki da kyau ba.
Nawa ohms ya kamata wayar ƙasa ta kasance?
Ana tsammanin juriya a cikin gidan ku ba zai wuce 5 ohms ba, yayin da mafi kyawun ƙimar shine sifili (0) ohms. Mafi kusancin ƙimar juriya shine sifili, mafi kyawun ƙasa.
Menene sako-sako da waya ta ƙasa zata iya yi?
Ƙarƙashin ƙasa mara kyau zai sa fitilun fitulun ku su zama dusashe ko kyalli. Haka kuma yana haifar da gazawar na'urorin lantarki ko kuma daina aiki gaba ɗaya saboda rashin isasshen wutar lantarki.
