Setting The Sensing Interval - GRAPHTEC FC4500 User Manual

4.11 Setting the Sensing Interval

If the line segments are fine, registration marks may not be detected even when the slowest registration
mark detection speed has been set. If the interval has been set to 0, the registration marks are detected
through sampling during movement. If the interval is set to 5, 10 or 15μ, registration marks are sensed at the
specified interval. (FC4510-60 only)
The sensing interval setting is only enabled for registration mark pattern 3.
