4. # Scans Averaged - Sets the number of scans over which the elongation
measurements are averaged. The laser extensometer uses a moving window
method of averaging which allows smooth performance. Increasing the
number of scans averaged improves resolution and slows response time
(that is, bandwidth) of the elongation measurement. The choices are as
follows:
2 Scans Averaged
4 Scans Averaged
8 Scans Averaged
16 Scans Averaged
32 Scans Averaged
64 Scans Averaged
128 Scans Averaged
256 Scans Averaged
512 Scans Averaged
