* Output Cutoff Point

The cutoff point is used to prevent square root extraction at between 0-15% of the output signal.  The reason for this is that as the output signal decreases, input values become too small for accurate calculation, as illustrated in the chart below.  The cutoff point of 15% F.S. will not interfere with the performance of the unit.
