Non-Linearity
Non-linearity is computed as the maximum error from a best fit (least squares) line and divided
by the full range. A system with a non-linearity of
± 0.2%FR and a ± 10 mil ( ± 0.25mm) range (20
mil (0.5mm) Full Range) would have a maximum deviation of 0.2%x20mil=0.04mils
(0.2%x0.5mm=0.001mm).
