DTECT PRECISION
Select detection precision. You can select one of
two levels (standard/high), according to your
conditions, the desired precision level for
detection results, and the detection speed.
For details, see page 3-20.
REGISTER NO.
Enter a register number. When making positional
deviation measurements, you can select any
register from 0 to 7 (a total of 8 registers).
MODE
Select a mode for detection.
The details of each mode are as follows.
Gray search See page 3-20.
Edge detection See page 3-25.
DTECT ANGL and ANGLE UNIT
When the "1P-SCH" or "1P-SCH + 1P-EDGE" is selected in " MODE," you can specify angle
detection.
For details about angle detection, see page 4-12.
Select a detection range on the " DTECT ANGL" line and select the units at " ANGLE UNIT."
REGISTER NO. ( MDL 0, MDL 1)
The specified modes are displayed for each register number on these lines. When a 1-point search
or 1-point edge is specified, only " MDL 0" will be available. When a 2-point search, 2-point edge,
or 1-point search and 1-point edge is specified, " MDL 1" is also available.
The "S" in the table indicates a gray search, and the "E" indicates edge detection. "X" means not
used.

Detection Mode Details Usable models
NO (None) Does not detect.
1P-SCH
(1-point search)
Detect the positional deviation of one point in the
scanned image compared to a single reference image,
after performing a gray search.
Model 0 only
2P-SCH
(2-point search)
Detect the positional deviation of two points in the
scanned image compared to two reference images,
after performing a gray search.
Model 0 and 1
1P-EDGE
(1-point edge)
Detect the positional deviation of one point in the
scanned image compared to a single reference image,
after performing edge detection.
Model 0 only
2P-EDGE
(2-point edge)
Detect the positional deviation of two points in the
scanned image compared to two reference images,
after performing edge detection.
Model 0 and 1
1P-SCH + 1P-EDGE
(1-point search and
1-point edge)
Detect the positional deviation of two points, one point
after performing a gray search and one point after
performing edge detection.
Model 0 and 1
