■ T-EDGE (Top Edge)/B-EDGE (Bottom Edge)
Select either of these settings for the gap
measurement or positioning of rollers.
When the LS-7000 Series is in T-EDGE measurement operation, it measures the width of
the bright portion between the top of the measuring head and the first shadow in the
measuring area.
When the LS-7000 Series is in B-EDGE measurement operation, it measures the width of
the bright portion between the bottom of the measuring area and the bottom of the last
object in the beam.

Tips Setting the reference edge within the measuring area enables measurements
in higher repeat accuracy.
■ SEG (Segment)
Select this setting for the measurement of the inner diameters of discs or the measure-
ment of pitches.
The edge where the measurement of the object in the measuring area starts is called
“start edge” and the edge where the measurement terminates is called “end edge.” The
space between these edges specified is measured.
Segment measurement is performed in E mode or P mode. If objects are measured
with the virtual center of the light axis set, use edge 0.
Setting Range
• Edge or pitch numbers can be designated between –127 and 127.
• The duplicated designation of an edge or pitch number will set the measured value to
0.
• If edges or pitches are designated in reverse order, negative measured values will be
obtained.
