I-Multimeter Diode Symbol (Imanuwali)
Ukuhlolwa kwe-Diode kuyindlela ephumelela kakhulu futhi esesikhathini samanje yokuhlola ukuthi ama-diode akho asesimweni esihle noma esibi. I-diode iyisisetshenziswa sikagesi esivumela ukugeleza kwamanje ngendlela ethile. Ine-cathode (negative) kanye ne-anode (positive) iziphetho.
Ngakolunye uhlangothi, i-multimeter iyithuluzi lokulinganisa elingasetshenziswa ukukala ukumelana, i-voltage, kanye nesimanje. Izimpawu ze-multimeter etholakala kuyo zisiza ukwenza imisebenzi yayo ehlukahlukene. Iphinde ifike ne-test lead. Bheka uhlu olugcwele lapha.
Ngamafuphi, ukuhlola i-diode, kufanele uthathe izinyathelo ezilandelayo. Okokuqala, vula ukudayela kwakho kwe-multimeter kuphawu lokuhlola lwe-diode bese uvala amandla kusekethi yakho. Okulandelayo, xhuma amathiphu okuhlola ama-multimeter probes ku-diode. Ukuhola okunegethivu ekugcineni kwe-negative (cathode) ye-diode, kanye nokuholela okuhle ekugcineni (i-anode) ekupheleni kwe-diode, kuya phambili ngokuchema. Ngemuva kwalokho uzothola ukufundwa kwe-multimeter. Inani elivamile le-silicon diode enhle ngu-0.5 kuya ku-0.8V futhi i-germanium diode enhle ingu-0.2 kuya ku-0.3V. Shintsha umkhondo futhi uthinte i-diode iye kolunye uhlangothi, i-multimeter akufanele ibonise ukufunda ngaphandle kwe-OL.
Esihlokweni sethu, sizoxoxa ngokuningiliziwe mayelana nendlela yokuhlola i-diode nge-multimeter.
Uphawu lwe-multimeter diode
Uphawu lwe-diode kumasekhethi ngokuvamile luboniswa njengonxantathu onomugqa owela phezulu kukanxantathu. Lokhu kuhlukile ku-multimeter, ama-multimeters amaningi anemodi yokuhlola i-diode, futhi ukwenza ukuhlolwa kwe-diode, udinga ukuvula ukudayela kwe-multimeter kuphawu lwe-diode ku-multimeter. Uphawu lwe-diode ku-multimeter lubukeka njengomcibisholo okhomba ibha eqondile lapho umugqa usuka khona njalo.
Kunezimpawu eziningi ze-multimeter ku-multimeter ngayinye enemisebenzi eyabelwe, efana ne-Hertz, i-AC voltage, i-DC yamanje, i-capacitance, ukumelana, nokuhlolwa kwe-diode, phakathi kokunye. Kuphawu lwe-multimeter diode, umcibisholo ukhomba ohlangothini oluphozithivu bese ibha eqondile ikhomba ohlangothini olunegethivu.
Ukuhlolwa kwe-Diode
Ukuhlola i-diode kwenziwa kangcono kakhulu ngokulinganisa ukwehla kwamandla kagesi kuyo yonke i-diode lapho i-voltage kuyo yonke i-diode ivumela ukugeleza kwamanje kwemvelo, okungukuthi ukuchema phambili. Kusetshenziswa izindlela ezimbili zokuhlola ama-diode nge-multimeter yedijithali:
- Imodi yokuhlola i-Diode: Lena indlela engcono kakhulu futhi evame ukusetshenziswa kakhulu yokuhlola ama-diode. Lo msebenzi usuvele ukhona phakathi kwezimpawu ze-multimeter.
- Imodi yokumelana: Lena enye indlela ongayisebenzisa uma i-multimeter ingenayo imodi yokuhlola i-diode.
Izinqubo Zokuhlola I-Diode
- Vula ukudayela kwe-multimeter kuphawu lokuhlola lwe-diode ku-multimeter bese uvala amandla kusekethe yakho.
- Xhuma amathiphu okuhlola ama-multimeter probes ku-diode. Umthofu ongemuhle oya ekugcineni kwe-negative (cathode) we-diode, kanye nokuholela okuhle ekugcineni (i-anode) ekupheleni kwe-diode, uchelela phambili.
- Uzothola ukufundwa kwe-multimeter. Inani elijwayelekile le-silicon diode enhle lingu-0.5 kuya ku-0.8 V, kanti i-germanium diode enhle ingu-0.2 kuya ku-0.3 V (1, 2).
- Shintsha umkhondo bese uthinta i-diode ngakolunye uhlangothi, i-multimeter akufanele ibonise ukufunda ngaphandle kwe-OL.
Ukufingqa
Uma ukuhlolwa kufundwa ukuchema phambili, kubonisa ukuthi i-diode ivumela i-current ukugeleza ohlangothini oluthile. Ngesikhathi sokuhlehla, lapho i-multimeter ibonisa i-OL, okusho ukugcwala ngokweqile. I-multimeter enhle ibonisa i-OL uma i-diode enhle ichemile.
