• Ƙayyadaddun tsarin : Kunna/ kashe duk duba iyakokin tsarin.

• Sake saitin ta atomatik : Kunna/ kashe dawo da tashar atomatik.

• Matsayin Rukuni na A/B : Zaɓi ƙimar dubawa (4 Hz ko 25 Hz) da matatar mitar layi (50 Hz ko 60 Hz) don 8 na farko da 8 RTD na ƙarshe, bi da bi.

• Rukuni A/B Riba : Zaɓi yanayin riba ( Normal_1.0 , Gain_2.0 , 10 ohm Cu_10.0 ) don ƙungiyoyin RTD guda biyu. Gain_2.0 yana ba da daidaito mafi girma lokacin da juriya yayi ƙasa.

• Ma'auni na kowane-Tashar (na RTD1 zuwa RTD16):

• Nau'in RTD : Zaɓi daga nau'ikan tallafi guda 15, ko saita zuwa Mara amfani.

• SysLim1/2 Kunna/Latch/Nau'i/Iyaka : Daidaita saita saiti biyu na iyakokin ƙararrawar zafin jiki da dabaru (≥ ko ≤).
