An error may occur in the thickness measurement of
a transparent object depending on the refractive
index. In such a case, you can use the calibration
function to obtain the proper value.
Refer to "CALIB (calibration)" (page 5-16) for the
calibration function.
The [SLANT] can be set in OUT1 only and cannot be
set in OUT2.
The [SLANT] and [ ΔSLANT] can be selected only
when the scanning width is set to anything other than
[OFF] and [4/1].
Refer to "SCAN" (page 3-15) for setting scanning
width.
The measuring unit should be viewed in the direction
shown in the drawing. (+/–)

surface in a counterclockwise direction, the value is
regarded as "+", and when the target is slanted in a
clockwise direction, the value is regarded as "–".
