Damping
Minimum damping allows fast response to level changes.
Increasing damping slows the OCF 5.0's response to level changes
and is ideal to smooth the display and outputs in turbulent
conditions. Damping value is shown in percent (0-99%). Some
experimentation may be required to select the optimum damping
value. A value of 1% is recommended for most applications and for
fast level changes (up to ½ inch/sec - 13 mm/sec).
