Damping
The type of filter you choose determines the damping function.
With the RC exponential method, the damping entry is equivalent to a time constant; that is,
the amount of time (in seconds) that it takes for the gauge reading to achieve 63.2% of a step
change in process. A range of integer values from 1–600 seconds is possible for this time
constant entry.
With the rectangular window filtering, the damping entry determines how many samples to
use when calculating the average, responding to 100% of a process step change. The
maximum damping entry is 100 with this type of filtering.
Fast response cutoff
Fast response cutoff temporarily bypasses the RC or digital filtering when the change in
process exceeds this value (in engineering units) between successive samples. This enables
the W-4510 to respond immediately to large step changes while filtering the smaller
variations in the signal caused by noise and normal process variations. To turn off the fast
cutoff filter, set the value to zero.
