Damping Factor is a measure of speed, overshoot, and undershoot in which the
process variable responds to the output changes of the instrument, which were
used during the Auto Tune. This value is typically set to the ratio of Rate to
Reset. This Default value is (0003). For fast response time, this value should be
decreased while for slow response time it should be increased.
The "DEADBAND" Submenu will only appear if "ON/OFF" was
selected from the "Control Type" Menu.
