function

*Three window display function is used to display the measured value, given value and valve feedback value, which makes the instrument data display more clear and intuitive.

*Zero and full correction, cold junction compensation, digital filtering, sensor fault processing, communication interface, 60 segment broken line input correction, program control, switch input, switch output and other extended functions.

*Multi type input with different input signals (thermocouple / thermal resistance / linear voltage, linear current / linear resistance).

*With / without feedback function can be set, self calibration valve position.

*PID intelligent regulation algorithm, accurate and stable control, no overshoot, with high-precision self-tuning (at) function.
