Alamar Diode Multimeter (Manual)

Gwajin diode ita ce hanya mafi inganci kuma ta zamani don bincika idan diodes ɗin ku na cikin yanayi mai kyau ko mara kyau. Diode na'urar lantarki ce da ke ba da damar halin yanzu don gudana ta takamaiman hanya. Yana da cathode (korau) da anode (tabbatacce) ƙare.

A gefe guda kuma, na'urar multimeter shine kayan aunawa wanda za'a iya amfani dashi don auna juriya, ƙarfin lantarki, da halin yanzu. Alamomin multimeter da ke kan sa suna taimakawa wajen aiwatar da ayyuka daban-daban. Hakanan yana zuwa tare da jagorar gwaji. Duba cikakken jerin anan.

A takaice, don gwada diode, dole ne ku ɗauki matakai masu zuwa. Da farko, kunna bugun kiran ku na multimeter zuwa alamar gwajin diode kuma kashe wuta a kewayen ku. Na gaba, haɗa tukwici na bincike na multimeter probes zuwa diode. Mummunan gubar zuwa mummunan (cathode) ƙarshen diode, da kuma kyakkyawan jagoranci zuwa ƙarshen diode (anode) na diode, yana nuna son kai. Sannan zaku sami karatun multimeter. Matsakaicin ƙima don diode silicon mai kyau shine 0.5 zuwa 0.8V kuma diode mai kyau na germanium shine 0.2 zuwa 0.3V. Musanya jagororin kuma taɓa diode a kishiyar shugabanci, multimeter yakamata ya nuna babu karatu banda OL.

A cikin labarinmu, za mu tattauna dalla-dalla yadda za a gwada diode tare da multimeter.

Alamar diode Multimeter

Alamar diode a cikin da'irori yawanci ana kwatanta shi azaman alwatika mai layi mai haye saman triangle. Wannan ya bambanta da na'ura mai mahimmanci, yawancin multimeters suna da yanayin gwajin diode, kuma don yin gwajin diode, kuna buƙatar kunna bugun kiran multimeter zuwa alamar diode akan multimeter. Alamar diode akan multimeter tana kama da kibiya mai nuni zuwa sandar tsaye wacce layi ke fita koyaushe.

Akwai alamomin multimeter da yawa akan kowane multimeter waɗanda suka sanya ayyuka, kamar Hertz, ƙarfin lantarki na AC, halin yanzu na DC, ƙarfin ƙarfi, juriya, gwajin diode, da sauransu. Don alamar diode multimeter, kibiya tana nuni zuwa gefen tabbatacce kuma mashaya ta tsaye tana nuni zuwa ga mara kyau.

Gwajin diode

Gwajin diode yana da kyau ta hanyar auna raguwar ƙarfin lantarki a kan diode lokacin da ƙarfin lantarki a cikin diode ya ba da damar kwararar yanayin halin yanzu, watau son rai na gaba. Ana amfani da hanyoyi guda biyu don gwada diodes tare da multimeter na dijital:

1. Yanayin gwajin diode: Wannan ita ce hanya mafi kyau kuma mafi yawan amfani da ita don gwajin diodes. Wannan aikin ya riga ya kasance tsakanin alamomin multimeter.
2. Yanayin juriya: Wannan wata hanya ce da za a yi amfani da ita idan multimeter ba shi da yanayin gwajin diode.

Hanyoyin Gwajin Diode

• Juya bugun kirar multimeter zuwa alamar gwajin diode akan multimeter kuma kashe wuta zuwa kewayen ku.
• Haɗa tukwici na bincike na multimeter probes zuwa diode. Mummunan gubar zuwa mummunan (cathode) ƙarshen diode, da kuma kyakkyawan jagoranci zuwa ƙarshen diode (anode) na diode, yana nuna son kai.
• Sannan zaku sami karatun multimeter. Matsakaicin ƙima na diode silicon mai kyau shine 0.5 zuwa 0.8 V, kuma diode mai kyau na germanium shine 0.2 zuwa 0.3 V (1, 2).
• Canja jagorar kuma taɓa diode a kishiyar shugabanci, multimeter bai kamata ya nuna karatu ba sai OL.

Don taƙaita

Lokacin da gwajin ya karanta don son rai na gaba, yana nuna cewa diode yana ƙyale halin yanzu ya gudana a wata hanya ta musamman. A lokacin nuna son kai, lokacin da multimeter ya nuna OL, wanda ke nufin wuce gona da iri. Kyakkyawan multimeter yana nuna OL lokacin da diode mai kyau ya koma baya.
