Letšoao la Multimeter Diode (Manual)
Teko ea diode ke mokhoa o sebetsang ka ho fetesisa le oa morao-rao oa ho lekola hore na li-diode tsa hau li maemong a matle kapa a mabe. Diode ke sesebelisoa sa motlakase se lumellang hore hona joale ho phalle ka tsela e itseng. E na le lipheletso tsa cathode (negative) le anode (positive).
Ka lehlakoreng le leng, multimeter ke sesebelisoa sa ho metha se ka sebelisoang ho lekanya ho hanyetsa, motlakase le hona joale. Matšoao a multimeter a teng ho eona a thusa ho etsa mesebetsi ea eona e fapaneng. E boetse e tla le tataiso ea tlhahlobo. Sheba lenane le felletseng mona.
Ka bokhutšoanyane, ho hlahloba diode, o tlameha ho nka mehato e latelang. Taba ea mantlha, retelletsa mohala oa hau oa multimeter ho letšoao la tlhahlobo ea diode ebe o tima motlakase ho potoloho ea hau. Ka mor'a moo, amahanya lintlha tsa probe tsa li-multimeter probes ho diode. The negative lead to the negative (cathode) qetellong ea diode, le positive lead to positive (anode) qetellong ea diode, ke pele leeme. Joale u tla fumana 'malo oa multimeter. Boleng bo tloaelehileng bakeng sa diode e ntle ea silicon ke 0.5 ho 0.8V le germanium diode e ntle ke 0.2 ho 0.3V. Fetola li-lead le ho ama diode ka lehlakoreng le leng, multimeter ha ea lokela ho bontša ho bala ntle le OL.
Sehloohong sa rona, re tla tšohla ka ho qaqileng haholoanyane mokhoa oa ho lekola diode ka multimeter.
Letšoao la multimeter diode
Letšoao la diode lipotolohong hangata le tšoantšoa e le khutlo-tharo e nang le mola o fetang kaholimo ho kgutlotharo. Sena se fapane le multimeter, li-multimeters tse ngata li na le mokhoa oa tlhahlobo ea diode, 'me ho etsa tlhahlobo ea diode, u lokela ho fetola mohala oa multimeter ho letšoao la diode ho multimeter. Letšoao la diode ho multimeter le shebahala joalo ka motsu o supang bareng e otlolohileng eo mola o tlohang kamehla.
Ho na le matšoao a 'maloa a multimeter ho multimeter e' ngoe le e 'ngoe e abetsoeng mesebetsi, joalo ka Hertz, voltage ea AC, DC hajoale, bokhoni, ho hanyetsa, le tlhahlobo ea diode, har'a tse ling. Bakeng sa letšoao la multimeter diode, motsu o supa lehlakoreng le letle 'me bar e otlolohileng e supa lehlakoreng le fosahetseng.
Liteko tsa diode
Teko ea diode e molemo ka ho fetisisa ka ho lekanya ho theoha ha motlakase ho pholletsa le diode ha motlakase ho pholletsa le diode o lumella ho phalla ha tlhaho, ke hore, ho ea pele. Ho sebelisoa mekhoa e 'meli ho lekola diode ka multimeter ea dijithale:
- Mokhoa oa tlhahlobo oa diode: Ena ke mokhoa o molemo ka ho fetisisa le o sebelisoang haholo oa ho etsa liteko tsa diode. Mosebetsi ona o se o ntse o le teng har'a matšoao a multimeter.
- Resistance Mode: Ena ke mokhoa o mong o ka sebelisoang haeba multimeter e se na mokhoa oa tlhahlobo oa diode.
Mekhoa ea Teko ea Diode
- Fetolela mohala oa multimeter ho letšoao la tlhahlobo ea diode ho multimeter ebe o tima motlakase potolohong ea hau.
- Hokela lintlha tsa probe tsa li-multimeter probes ho diode. The negative lead to the negative (cathode) qetellong ea diode, le positive lead to positive (anode) qetellong ea diode, ke pele leeme.
- Joale u tla fumana 'malo oa multimeter. Boleng bo tloaelehileng bakeng sa diode e ntle ea silicon ke 0.5 ho 0.8 V, 'me e ntle ea germanium diode ke 0.2 ho 0.3 V (1, 2).
- Fapanya lithapo ebe u ama diode ka lehlakoreng le leng, multimeter ha ea lokela ho bonts'a ho bala ntle le OL.
Ho akaretsa
Ha tlhahlobo e baloa ho ea pele, e bontša hore diode e lumella hona joale ho phalla ka tsela e itseng. Nakong ea leeme le ka morao, ha multimeter e bonts'a OL, e bolelang ho feta. Multimeter e ntle e bonts'a OL ha diode e ntle e leeme.
