Enhanced measuring functions
• Height/tilt adjustment unit (Standard accessory)
The height/tilt adjustment unit comes as standard for leveling the drive unit prior to making skidless measurements and, supported by guidance from
the unique D.A.T. function, makes it easy to achieve highly accurate alignment.
When the SJ-410 Series detector is mounted on the manual column stand* 1 for measurement, it can be combined with any of the optional products for easier
leveling: leveling table* 1 , 3-axis alignment table* 1 or tilt adjustment unit* 1 .
*1: For details about optional products, see P6-7.

• Skidded measurement
In skidded measurements, surface features are measured with reference
to a skid following close behind the stylus. This cannot measure
waviness and stepped features exactly but the range of movement
within which measurement can be made is greater because the skid
tracks the workpiece surface contour.
• Skidless measurement
Skidless measurement is where surface features are measured relative
to the drive unit reference surface. This measures waviness and finely
stepped features accurately, in addition to surface roughnness, but
range is limited to the stylus travel available. The SJ-410 series supports
a variety of surface feature measurements simply by replacing the
stylus.
