Kuyesa kwa diode ndiyo njira yabwino kwambiri komanso yaposachedwa yowonera ngati ma diode anu ali bwino kapena oyipa. Diode ndi chipangizo chamagetsi chomwe chimalola kuti magetsi aziyenda mbali ina yake. Ili ndi ma cathode (negative) ndi anode (zabwino) malekezero.

Kumbali ina, multimeter ndi chida choyezera chomwe chingagwiritsidwe ntchito kuyeza kukana, mphamvu yamagetsi, ndi mphamvu. Zizindikiro za multimeter zomwe zili pamenepo zimathandizira kuchita ntchito zake zosiyanasiyana. Zimabweranso ndi mayeso otsogolera. Onani mndandanda wonse apa.

Mwachidule, kuyesa diode, muyenera kuchita zotsatirazi. Choyamba, tembenuzirani kuyimba kwanu kwa ma multimeter kukhala chizindikiro cha mayeso a diode ndikuzimitsa magetsi kudera lanu. Kenaka, gwirizanitsani nsonga za kafukufuku wa multimeter probes ku diode. Njira yolakwika yopita kumapeto (cathode) kumapeto kwa diode, ndi kutsogolera kwabwino (anode) kumapeto kwa diode, ndikokondera kutsogolo. Ndiye mudzapeza kuwerenga kwa multimeter. Mtengo wamtengo wapatali wa silicon diode wabwino ndi 0.5 mpaka 0.8V ndipo germanium diode yabwino ndi 0.2 mpaka 0.3V.

M'nkhani yathu, tikambirana mwatsatanetsatane momwe tingayesere diode ndi multimeter.

Chizindikiro cha multimeter diode

Chizindikiro cha diode m'mabwalo nthawi zambiri chimawonetsedwa ngati makona atatu okhala ndi mzere wodutsa pamwamba pa makona atatu. Izi ndizosiyana ndi ma multimeter, ma multimeter ambiri amakhala ndi mayeso a diode, ndipo kuti muyese mayeso a diode, muyenera kutembenuza kuyimba kwa multimeter kukhala chizindikiro cha diode pa multimeter. Chizindikiro cha diode pa multimeter chikuwoneka ngati muvi wolozera ku kapamwamba komwe mzere umachoka nthawi zonse.

Pali ma multimeter angapo pa ma multimeter aliwonse omwe apatsidwa ntchito, monga Hertz, AC voltage, DC current, capacitance, resistance, ndi diode test, pakati pa ena. Kwa chizindikiro cha multimeter diode, muvi umaloza ku mbali yabwino ndipo mipiringidzo yowongoka imaloza ku mbali yolakwika.

Mayeso a diode

Kuyesa kwa diode kumachitika bwino poyesa kutsika kwamagetsi pa diode pomwe voteji kudutsa diode imalola kuyenda kwachilengedwe, mwachitsanzo, kukondera kutsogolo. Njira ziwiri zimagwiritsidwa ntchito poyesa ma diode ndi multimeter ya digito:

  1. Mayeso a Diode: Iyi ndiye njira yabwino kwambiri komanso yomwe imagwiritsidwa ntchito kwambiri poyesa ma diode. Ntchitoyi ilipo kale pakati pa zizindikiro za multimeter.
  2. Resistance Mode: Iyi ndi njira ina yogwiritsira ntchito ngati multimeter ilibe njira yoyesera ya diode.

Njira Zoyeserera za Diode

  • Sinthani kuyimba kwa ma multimeter kukhala chizindikiro cha mayeso a diode pa multimeter ndikuzimitsa magetsi kudera lanu.
  • Lumikizani nsonga za probe za multimeter probes ku diode. Njira yolakwika yopita kumapeto (cathode) kumapeto kwa diode, ndi kutsogolera kwabwino (anode) kumapeto kwa diode, ndikokondera kutsogolo.
  • Kenako mupeza kuwerenga kwa multimeter. Mtengo wabwino wa silicon diode ndi 0.5 mpaka 0.8 V, ndipo germanium diode yabwino ndi 0.2 mpaka 0.3 V (1, 2).
  • Sinthani mayendedwe ndikukhudza diode mbali ina, ma multimeter sayenera kuwonetsa kuwerenga kupatula OL.

Kufotokozera mwachidule

Mayeso akamawerengera kukondera kutsogolo, zikuwonetsa kuti diode imalola kuti pakali pano ikuyenda mbali ina. Panthawi yotsatsira, pomwe ma multimeter akuwonetsa OL, zomwe zikutanthauza kulemetsa. Multimeter yabwino imawonetsa OL pamene diode yabwino imakondera.
