After you have completed the auto-tune sequence and have transferred the suggested
tuning parameters to the CPU, you can use the control panel to monitor your loop's response
to a step change in the setpoint.
In the figure below, the loop responds to a setpoint change with the original tuning
parameters (before running auto-tune). Notice the overshoot and the long, damped ringing
behavior of the process using the original tuning parameters.
