Yanayin diode multimeter (manual da umarnin don amfani)

Diode na'ura ce ta lantarki da ke ba da damar wutar lantarki ta gudana ta cikin ta ta hanya ɗaya kawai, ba akasin haka ba. Semiconductor diodes yawanci suna da ƙa'idar ƙira ta gabaɗaya, wanda shine nau'in semiconductor na nau'in P wanda aka haɗa da toshe na nau'in semiconductor na nau'in N kuma an haɗa shi zuwa tashoshi biyu, wato anode da cathode.

Da'irar gyarawa da'ira ce ta lantarki mai ɗauke da kayan lantarki waɗanda ke canza canjin halin yanzu zuwa na yanzu kai tsaye. Ana amfani da da'irar gyarawa a cikin kayan wutar lantarki na DC ko na'urorin gano siginar RF a cikin kayan aikin rediyo. Da'irar gyara yawanci tana ƙunshe da diodes semiconductor don sarrafa fitilun gyara na yanzu da mercury ko wasu abubuwan haɗin gwiwa.

Gabaɗaya, hanya mafi kyau don gwada diode shine amfani da yanayin "Diode Test" akan multimeter ɗin ku, saboda wannan yanayin yana da alaƙa kai tsaye da halayen diode. A cikin wannan hanyar, diode yana nuna son kai. Diode mai aiki na yau da kullun zai ɗauki halin yanzu lokacin da aka nuna son kai kuma yakamata ya sami raguwar ƙarfin lantarki. Idan darajar ƙarfin lantarki da aka nuna yana tsakanin 0.6 da 0.7 (na silicon diode), to diode yana da kyau da lafiya.

Matakan auna diode a cikin yanayin "Test Diode".

• Ƙayyade ingantattun sanduna mara kyau da mara kyau na diodes.
• Ajiye multimeter ɗin ku na dijital (DMM) a cikin yanayin gwajin diode. A cikin wannan yanayin, multimeter yana da ikon isar da kusan 2 mA tsakanin gwajin gwajin.(2)
• Haɗa jagorar gwajin baƙar fata zuwa mara kyau kuma jajayen gwajin ja zuwa tabbataccen tasha.
• Kula da karatun akan nunin multimeter. Idan darajar ƙarfin lantarki da aka nuna yana tsakanin 0.6 da 0.7 (na silicon diode), to diode yana da kyau da lafiya. Don diodes na germanium, wannan ƙimar tana daga 0.25 zuwa 0.3.
• Yanzu musanya tashoshi na mita kuma haɗa binciken baƙar fata zuwa madaidaicin tasha da jan binciken zuwa mara kyau. Wannan shine juyar da yanayin son zuciya na diode lokacin da babu halin yanzu yana gudana ta cikinsa. Saboda haka, mita ya kamata ya karanta OL ko 1 (daidai da budewa) idan diode yana da kyau.

Idan mitar ta nuna ƙimar da ba ta da alaƙa da sharuɗɗan biyu na sama, to diode (1) ba daidai ba ne. Lalacewar diode na iya zama buɗe ko gajere.
