Мақалада термоэлектрлік әдіс кезіндегі көп нүктелі контактіні модельдеу нәтижелері келтірілген. ТермоЭҚК көздерінің әртүрлі түрлерінің бірнеше терможұптарды параллель қосу арқылы алынған эквивалентті термоЭҚК көзінің жүктеме сипаттамасына әсері көрсетілген. Ұсынылған модель еркін қол жетімді NI LabVIEW пакетінде жүзеге асырылған. Модельді тексеру терможұптардың үш түрінде жүзеге асырылды: мыс\константан, мыс\нихром және хромель\алюмель, олардың параллель қосылғанжәне саны әртүрлі. Алынған эквивалентті көздің есептік жүктеме сипаттамалары эксперименттік сипаттамалардан 6% - дан аспайды. Терможұптардың екі түрінің әр түрлі санын параллель қосу арқылы алынған эквивалентті термоЭҚК көзінің жүктеме сипаттамаларын модельдеу нәтижелері келтірілген. Сенімді мәліметтерді алу үшін кем дегенде 1 кОм-ның баламалы көзінің жүктемесін қамтамасыз ету қажет екендігі көрсетілген.
