Yadda za a gwada firikwensin matsa lamba 3-waya?
A ƙarshen wannan labarin, za ku san yadda ake gwada firikwensin matsa lamba mai waya uku.
Gwajin firikwensin matsin waya 3 na iya zama da wahala. A ƙarshe, za ku duba duk wayoyi uku don samun ƙarfin lantarki. Waɗannan wayoyi suna da ƙarfin lantarki daban-daban. Don haka, ba tare da kyakkyawar fahimta da kisa ba, zaku iya ɓacewa, wanda shine dalilin da yasa na zo nan don taimakawa!
Gabaɗaya, don gwada firikwensin matsa lamba 3-waya:
- Saita multimeter zuwa yanayin auna wutar lantarki.
- Haɗa baƙar gubar na multimeter zuwa tashar baturi mara kyau.
- Haɗa jan bincike na multimeter zuwa tabbataccen tashar baturi kuma duba ƙarfin lantarki (12-13 V).
- Juya maɓallin kunnawa zuwa matsayin ON (kada ku fara injin).
- Nemo firikwensin matsa lamba.
- Yanzu duba masu haɗin uku na firikwensin waya uku tare da binciken jajayen multimeter kuma yi rikodin karatun.
- Ramin guda ya kamata ya nuna 5V kuma ɗayan yakamata ya nuna 0.5V ko dan kadan mafi girma. Ramin ƙarshe ya kamata ya nuna 0V.
Don ƙarin bayani, bi post ɗin da ke ƙasa.
Kafin mu fara
Kafin ci gaba zuwa sashin aiki, akwai wasu abubuwa da ya kamata ku sani.
Fahimtar wayoyi uku a cikin firikwensin matsa lamba na iya taimaka muku da yawa lokacin gwada firikwensin. Don haka bari mu fara da wannan.
Daga cikin wayoyi guda uku, waya daya ita ce hanyar sadarwa, daya kuma ita ce siginar. Na ƙarshe shine wayar ƙasa. Kowane ɗayan waɗannan wayoyi yana da ƙarfin lantarki daban-daban. Anan akwai wasu cikakkun bayanai game da ƙarfin ƙarfin su.
- Wayar ƙasa dole ne ta zama 0V.
- Wayar magana dole ne ta sami 5V.
- Idan injin yana kashe, wayar siginar ya kamata ta zama 0.5V ko dan kadan sama.
Lokacin da aka kunna injin, wayar siginar tana nuna ƙarfin lantarki mai mahimmanci (5 da ƙasa). Amma zan yi wannan gwajin ba tare da kunna injin ba. Wannan yana nufin cewa ƙarfin lantarki ya zama 0.5 V. Zai iya tashi kadan.
Tushen ranar: Wayoyin firikwensin matsa lamba sun zo cikin haɗin launi daban-daban. Babu ainihin lambar launi don waɗannan firikwensin wayoyi.
Menene Reverse Probing?
Dabarar da muke amfani da ita a wannan tsarin gwaji ana kiranta reverse probing.
Duba halin yanzu na na'ura ba tare da cire haɗin ta daga mai haɗawa ba ana kiran shi reverse probing. Wannan babbar hanya ce don gwada juzu'in wutar lantarki na firikwensin matsa lamba a ƙarƙashin kaya.
A cikin wannan demo, zan bi ku ta yadda ake gwada firikwensin motsi na waya 3. Motar ta zo da nau'ikan na'urori daban-daban, kamar na'urori masu auna karfin iska, na'urorin hawan taya, na'urori masu auna matsa lamba, na'urori masu auna siginar man fetur, da dai sauransu. Misali, na'urar motsin iska tana gano yanayin yanayi (XNUMX).
Jagoran Mataki na 7 don Gwaji Sensor Matsayin Waya 3
Na'urar firikwensin dogo mai yana lura da matsa lamba mai. Wannan firikwensin yana cikin wuri mai sauƙi a cikin abin hawan ku. Don haka wannan firikwensin waya 3 shine mafi kyawun zaɓi don wannan jagorar. (2)
Mataki 1 - Saita multimeter ɗin ku zuwa yanayin ƙarfin lantarki
Da farko, saita multimeter zuwa yanayin wutar lantarki akai-akai. Juya bugun kira zuwa wurin da ya dace. Wasu na'urori masu yawa suna da ikon sarrafa kansa wasu kuma ba su da. Idan haka ne, saita tazarar zuwa 20V.
Mataki 2 - Haɗa baƙar fata waya
Sannan haɗa baƙar gubar na multimeter zuwa mummunan tasha na baturi. Bakar waya dole ne ta ci gaba da kasancewa a kan mara kyau har sai wannan gwajin ya cika. Kuna iya amfani da wannan haɗin a matsayin ƙasa don wannan gwajin.
Mataki na 3 - Duba ƙasa
Sa'an nan kuma haɗa jajayen gubar na multimeter zuwa tashar baturi mai kyau kuma duba karatun.
Ya kamata karatun ya kasance sama da 12-13V. Wannan babbar hanya ce don bincika ƙasa. Hakanan zaka iya duba matsayin wutar lantarki da wannan matakin.
Mataki 4 - Nemo firikwensin waya 3
Na'urar firikwensin dogo na man fetur yana gaban layin dogo mai.
Mataki 5 - Juya maɓallin kunnawa zuwa wurin ON
Yanzu shiga motar kuma kunna maɓallin kunnawa zuwa matsayin ON. Ka tuna, kar a kunna injin.
Mataki na 6 - Duba wayoyi uku
Saboda kun yi amfani da hanyar bincike ta baya, ba za ku iya cire wayoyi daga mahaɗin ba. Ya kamata a sami ramummuka guda uku a bayan firikwensin. Waɗannan ramummuka suna wakiltar tunani, sigina, da wayoyi na ƙasa. Don haka, zaku iya haɗa wayar multimeter zuwa gare su.
- Ɗauki jan gubar na multimeter kuma haɗa shi zuwa mahaɗin na 1st.
- Rubuta karatun multimeter.
- Yi haka don sauran ramummuka biyun da suka rage.
Yi amfani da shirin takarda ko fil ɗin aminci lokacin haɗa jajayen waya zuwa ramummuka uku. Tabbatar cewa faifan takarda ko fil ɗin yana gudana.
Mataki na 7 - Yi nazarin karatun
Ya kamata yanzu ku sami karatu uku a cikin littafin ku na rubutu. Idan firikwensin yana aiki da kyau, zaku sami karatun ƙarfin lantarki masu zuwa.
- Ya kamata karatu ɗaya ya zama 5V.
- Ya kamata karatu ɗaya ya zama 0.5V.
- Ya kamata karatu ɗaya ya zama 0V.
An haɗa ramin 5V zuwa waya mai tunani. Mai haɗin 0.5V yana haɗi zuwa siginar siginar kuma mai haɗin 0V yana haɗi zuwa wayar ƙasa.
Don haka, kyakkyawar firikwensin matsa lamba mai waya uku yakamata ya ba da karatun da ke sama. Idan hakan bai faru ba, kuna ma'amala da na'urar firikwensin da ba daidai ba.
Dubi wasu labaran mu a kasa.
- Yadda ake duba fitar baturi tare da multimeter
- Yadda ake bincika wutar lantarki ta PC tare da multimeter
