Yadda ake gwada capacitor tare da multimeter

Sau da yawa mutane suna tambayata yadda ake gwada capacitor da multimeter.

Halin capacitor shine ya yi caji da sakin makamashi da sauri fiye da baturi saboda yana adana makamashi daban, kodayake ba zai iya adana adadin daidai ba. Wannan yana da amfani sosai kuma shine dalilin da yasa zaku iya samun capacitor akan kusan kowane PCB.

The capacitor yana adana makamashin da aka fitar don daidaita katsewar wutar lantarki.

A cikin babban capacitor, muna da faranti guda biyu, yawanci ana yin su da aluminium, waɗanda aka raba su da kayan insulating dielectric kamar yumbu.

Dielectric yana nufin cewa abu zai yi polarize lokacin da yake hulɗa da filin lantarki. A gefen capacitor, zaku sami alama da mashaya da ke nuna wane gefen (terminal) mara kyau.

Hanyoyi don gwada capacitor tare da multimeter

Da farko dole ne ku tabbatar kun san abin da kuke yi. Karanta gargaɗin a hankali kafin amfani da waɗannan hanyoyin gwajin capacitor.

Hakanan yakamata ku tantance manyan hanyoyin gazawa, wanda ke nufin gazawar capacitor da ake zargi, don haka zaku iya sanin hanyar gwaji don amfani:

• Rage iya aiki
• Dielectric rushewa (gajeren kewayawa)
• Asarar hulɗa tsakanin faranti da gubar
• yayyo halin yanzu
• Ƙara ESR (daidai jerin juriya)

Duba capacitor tare da multimeter na dijital

1. Cire haɗin capacitor daga wutar lantarki, ko aƙalla a tabbata an cire haɗin waya ɗaya.
2. Tabbatar cewa capacitor ya cika. Ana iya samun wannan ta hanyar haɗa duka tashoshi na capacitor tare da sukurori.
3. Saita mita zuwa kewayon ohm (akalla 1k ohm)
4. Haɗa jagorar multimeter zuwa tashoshin capacitor. Tabbatar kun haɗa tabbatacce zuwa tabbatacce kuma mara kyau zuwa mara kyau.
5. Ma'aunin zai nuna ƴan lambobi na daƙiƙa sannan kuma nan da nan ya koma OL (layi mai buɗewa). Kowane ƙoƙari a mataki na 3 zai nuna sakamako iri ɗaya kamar na wannan matakin.
6. Idan babu canji, to capacitor ya mutu.

Duba capacitor a yanayin ƙarfin aiki.

Don wannan hanyar, kuna buƙatar mita mai ƙarfi akan multimeter, ko multimeter tare da wannan fasalin.

Wannan hanya ita ce mafi kyau don gwada ƙananan capacitors. Don wannan gwajin, canza zuwa yanayin iya aiki.

1. Cire haɗin capacitor daga wutar lantarki, ko aƙalla a tabbata an cire haɗin waya ɗaya.
2. Tabbatar cewa capacitor ya cika. Ana iya samun wannan ta hanyar haɗa duka tashoshi na capacitor tare da sukurori.
3. Zaɓi "Iri" akan na'urarka.
4. Haɗa jagorar multimeter zuwa tashoshin capacitor.
5. Idan karatun yana kusa da ƙimar da aka nuna akan kwalin kwandon capacitor, yana nufin cewa capacitor yana cikin yanayi mai kyau. Karatun na iya zama ƙasa da ainihin ƙimar capacitor, amma wannan al'ada ce.
6. Idan ba ka karanta capacitance ba, ko kuma idan capacitance ya yi ƙasa da yadda karatun ya nuna, capacitor ya mutu kuma yakamata a maye gurbinsa.

Duba Capacitor tare da gwajin wutar lantarki.

Wannan wata hanya ce ta gwada capacitor. Capacitors suna adana yuwuwar bambance-bambance a cikin caji, wanda shine ƙarfin lantarki.

A capacitor yana da anode (tabbataccen ƙarfin lantarki) da cathode (mara kyau ƙarfin lantarki).

Hanya ɗaya don gwada capacitor shine cajin shi da ƙarfin lantarki sannan ɗaukar karatu a cathode da anode. Don yin wannan, yi amfani da wutar lantarki akai-akai zuwa abubuwan da aka fitar. Polarity yana da mahimmanci a nan. Idan capacitor yana da tashoshi masu kyau da mara kyau, yana da madaidaicin capacitor wanda ingantaccen ƙarfin lantarki zai tafi zuwa ga anode da ƙarancin ƙarfin lantarki zuwa cathode.

1. Cire haɗin capacitor daga wutar lantarki, ko aƙalla a tabbata an cire haɗin waya ɗaya.
2. Tabbatar cewa capacitor ya cika. Ana iya samun wannan ta hanyar shunting duka tashoshi na capacitor tare da screwdriver, kodayake manyan capacitors sun fi fitar da su ta hanyar lodi.
3. Duba iyakar ƙarfin lantarki da aka yiwa alama akan capacitor.
4. Aiwatar da wutar lantarki, amma a kula don tabbatar da ƙarfin lantarkin bai kai abin da aka ƙididdige ƙarfin wutar lantarki ba; alal misali, zaku iya amfani da baturin 9 volt don cajin capacitor na 16 volt kuma ku tabbata kun haɗa abubuwan da suka dace zuwa kyakkyawan jagoranci na capacitor kuma mummunan yana haifar da mummunan jagoranci.
5. Yi cajin capacitor a cikin 'yan daƙiƙa kaɗan
6. Cire tushen wutar lantarki (batir)
7. Saita mita zuwa DC kuma haɗa voltmeter zuwa capacitor, haɗa tabbatacce-zuwa-tabbatacce da korau-zuwa-korau.
8. Duba ƙimar wutar lantarki ta farko. Ya kamata ya kasance kusa da ƙarfin lantarki da ake amfani da shi zuwa capacitor. Wannan yana nufin cewa capacitor yana cikin yanayi mai kyau. Idan karatun ya yi ƙasa sosai, ana cire capacitor.

Voltmeter zai nuna wannan karatun na ɗan ƙanƙanin lokaci saboda capacitor zai fita cikin sauri ta hanyar voltmeter zuwa 0V.
