Symbol is Perpendicular to Conveyor Movement
With the symbol bars perpendicular to the conveyor belt direction (Picket Fence
presentation) the relationship is:
V = (R x (F-W)) / N
where: V = Velocity of the conveyor (inches/second)
R = Scan Rate (640 scans/second)
F = Field width of scan beam
W = Symbol Width (inches)
N = Number of scans over symbol (minimum of 10 scans)
