Interpolation Method
This is used for interpolating between existing data in areas where profile data is missing (areas
where measurement is not possible).If there are lines where the workpieces cannot be
measured due to different degrees of reflectance or other causes, the data of such lines can be
obtained by interpolating between the data acquired from the lines that allow measurement as
desired.

Operation Manual
A measurement error signal is output for each area where
measurements could not be obtained.
Data for areas where measurements could not be obtained is
calculated by linear interpolation between the data to the left and
right. Up to 128 missing data values can be obtained by this
method.
Data for areas where measurements could not be obtained is
calculated by copying the data to the left.Up to 258 missing data
values can be obtained by this method.
