DSTB, oo ku saleysan DST / DSY fiiqan, resistors waxaa lagu qalabayn karaa qalabka xakamaynta heerkulka, badbaadada, quruxda iyo raaxaysiga, waxaan ku talinaynaa in loo sameeyo qaab bangiga load, kaas oo ogaan kara rakibidda kulaylka. taageere kala firdhiso, ilaalinta heerkulka heerkulka, ilaalinta xad-dhaafka ah iyo xad-dhaafka ah, qalabka digniinta, bandhigay digital multifunctional (muujin dhijitaalka ah ee awoodda, caabbinta, hadda, voltage, inta jeer, iwm) iyo hal unug leh AC iyo DC dual-ujeedo hawlaha.
● Marawaxada,qalabka,qalabka ilaalinta,qalabka digniinaha iwm.waa laheli karaa
● Labo weji ama saddex weji waxay noqon karaan isku-dubbarid la isku hagaajin karo, hal unug AC / DC dual-ujeedo, waxay muujin kartaa awoodda, caabbinta, hadda, voltaji, soo noqnoqoshada, iwm.
