Gentlemen, I am using an Omega 5550 temp ir with 4-20 input to plc. Trying to display the temp value has been discouraging. The displayed value is very unsteady. This project requires an operater temp input and when temp is reached the output turns off. Using an ez automation plc with analog card. also using their HMI.I have tried several math progrmming options and can not get a steady value to display. This is critical to the turn off temperature. Any help would be greatly appreiciated.
Thank you
Thank you
