Setup Manual
When measuring workpieces with level differences, the influence of the level
difference can be minimized by mounting the Sensor so that the plane containing
the emission axis and the reception axis is parallel to the boundary between the
different levels.
When measuring rotating workpieces, the influence of position displacement
and blurring of the rotating workpiece can be minimized by mounting the Sensor
so that the plane containing the emission axis and the reception axis is parallel
to the axis of rotation.
