Typically, operators will not store every cycle,
but will only store data when the crack grows
by a significant amount, such as 0.05 mm.

Specify the lower load limit for linear least
squares fit compliance used to determine

FCG Lower Least Squares
Fit Percentage

when to start saving data to disk. This
parameter is not used for FCG DCPD tests.

Specify the upper load limit for linear least
squares fit compliance used to determine

FCG Upper Least Squares
Fit Percentage

when to start saving data to disk. This
parameter is not used for FCG DCPD tests.
