Maximum Element Sizes by Lens Type at 4” (101.6mm) Focal Distance
Notes:
• Dynamic symbols that are close in size to the maximum field of view limitations may prove difficult to
read unless their vertical placements are precisely controlled.
• Good read opportunities are enhanced in Rapid Capture mode by ensuring the maximum number of
Rapid Captures occur while the symbol is in the field of view.
