Hanyoyin sarrafawa na ɗakin gwajin zafin jiki da zafi sun haɗa da Kafaffen gwajin ƙima(Hanyar FIX) da gwajin shirin (PROGHanya).
Saita maƙasudin zafin SP/SV. Idan gwajin zafin jiki ne mai girma, mita za ta kwatanta SV tare da ainihin ƙimar ƙimar PV na firikwensin. Idan PV ya kasance ƙasa da SV, mita OUT zai fitar da wutar lantarki na 3 ~ 12V DC don fitar da m jihar SSR Relay yana sarrafa dumama na injin don gane sarrafa kayan aiki ta atomatik. Lokacin da zafin jiki ya yi ƙasa, yana da mahimmanci don kunna maɓallin sanyaya da hannu da farko, kuma ɗakin aiki yana kwantar da hankali har sai ainihin zafin PV ɗin da aka yi shawarwari yana kusa da ƙimar SV.
