Mawonekedwe a LEDali ndi makhalidwe monga kuteteza chilengedwe, kuwala kwambiri, kumveka bwino, komanso kudalirika kwambiri.Ndi kupita patsogolo kwaukadaulo, zowonetsera zowonetsera za LED zagwiritsidwa ntchito kwambiri.Pansipa, tikuwonetsani njira zowunikira zomwe zimagwiritsidwa ntchito kwambiri pokonza zowonetsera zamagetsi za LED, ndikuyembekeza kukhala zothandiza kwa aliyense.
01 Njira yodziwira dera lalifupi
Khazikitsani multimeter kudera lalifupinjira yodziwira (nthawi zambiri ndi ntchito ya alamu, ngati ili yoyendetsa, imatulutsa phokoso la beep) kuti muwone ngati pali dera lalifupi.Ngati dera lalifupi likupezeka, liyenera kuthetsedwa mwamsanga.Kuzungulira kwakanthawi ndiyenso vuto lodziwika bwino la module yowonetsera ya LED.Zina zitha kupezeka poyang'ana ma IC mapini ndi mapini.Kuzindikira kwafupipafupi kuyenera kuchitika pamene dera lazimitsidwa kuti musawononge ma multimeter.Njirayi ndiyo yomwe imagwiritsidwa ntchito kwambiri, yosavuta komanso yothandiza.90% ya zolakwika zitha kudziwika ndikuweruzidwa kudzera munjira iyi.
02 Njira yodziwira kukana
Khazikitsani ma multimeter pamtundu wotsutsa, yesani mtengo wotsutsa pansi pa malo enaake pa bolodi loyenda bwino, ndiyeno yesani ngati pali kusiyana pakati pa mfundo yomweyi pa bolodi lina lofananira ndi mtengo wamba.Ngati pali kusiyana, kuchuluka kwa vuto kumatsimikiziridwa.
03 Njira yodziwira Voltage
Khazikitsani ma multimeter pamtundu wamagetsi, zindikirani mphamvu yapansi pamalo enaake omwe akuganiziridwa, yerekezerani ngati ili yofanana ndi mtengo wamba, ndikuzindikira mosavuta kuchuluka kwavuto.
04 Njira yodziwira kutsika kwamphamvu
Khazikitsani ma multimeter kukhala njira yodziwira kutsika kwa ma diode, popeza ma IC onse amapangidwa ndi zigawo zingapo zoyambira, zocheperako zokha.Choncho, pamene pali panopa akudutsa pa imodzi mwa zikhomo zake, padzakhala kutsika kwa magetsi pamapini.Nthawi zambiri, kutsika kwamagetsi pamapini omwewo amtundu womwewo wa IC kumakhala kofanana.Kutengera kutsika kwa voteji pamapini, ndikofunikira kugwira ntchito pamene dera lizimitsidwa.
