Cause
The reflected beam from
the beam emitting spot
is blocked.
The beam emitting spot
is applied to the R
portion (curved surface)
of the measurement
object.
The reflected beam has
directionality because
the surface of the object
is hairline-finished.
The received light
intensity is insufficient
because the sampling
cycle is too short.
The sampling cycle is
too long and this causes
excessive received light
intensity beyond the
adjustable range.

Corrective action
Move the position of the beam
projection spot or change the
mounting direction of the
sensor head so the reflected
beam should not be blocked.
Apply the beam projection spot
to the top of R portion or adjust
the beam diameter so it comes
larger by moving the
measurement object back and
forth within the measurement
range.
Check the mounting direction
of sensor head.
Set a longer sampling cycle or
shutter time (when shutter time
is set to a fixed value).
Set a shorter sampling cycle
and reduce the emitted light
intensity (enter a smaller
number to the shutter time).
