As stated above, the Output Menu and the subsequent Control Menu will change, depending upon the
Output Type selected. The settings shown here indicate what is available when an Output type is set for PID
Control.
Note: These parameters are automatically set during the autotune procedure. We do not recommend
altering the value of these control parameters unless your process requires manual tuning. We do, however,
recommend returning to this screen once an autotune is complete to record the values for the proportional,
derivative and integral actions that have been determined for your process.
