• Page 15: Tuning

  Tuning Tuning procedure allows to calculate PID parameters to obtain a good regulation. It means a stable control of temperature/ process on setpoint without fluctuations and fast response to deviations from setpoint caused by external noises. Tuning procedure includes calculation and setting of the following parameters: • Proportional band (system inertia in °C if temperature).
