Optimize manual tuning 

 

Manual tuning allows the operator to adjust tuning parameters by using one button to stabilize the system and 
another button to destabilize the system.  “Optimizing” allows for precise tuning by first making the system unstable, 
then re-stabilizing it.  NOTE:  System must be running to Manually Tune.
