7.1.2 Linear damping
If the process has fast step changes, linear (fast) damping gives shorter settling time. In the
linear damping (fast damping), the output is the running average of the signal during the
damping time. After a step change the signal rises linearly and reaches the final value after
the damping time. The linear damping gives the best trade-off between random noise
suppression and step change response time. Use the 4 DAMPING TIME menu item to set the
damping time.
For similar noise suppression a longer damping time has to be specified than for the
exponential damping.
The following figure shows how linear damping time affects the measurement.
