Setting the interpolation method
This is used for interpolating between data in areas where profile data is missing (areas
where measurement is not possible). If there are lines where the measurement target
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 for the lines that
allow measurement as desired.
Example: Profile output result when there are areas where measurement data cannot be
obtained

Description
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 64 missing data values can be obtained by this method.
(default value)
ON (linear interpolation is performed)
Data is calculated by linear interpolation
between the data to the left and right.
