Likewise, T

Therefore:
T
exp (max)
(code resolution). Values above the curve result in blurring. In practice, the
application values are somewhere below the theoretical line (in the green area),
due to environmental and other conditions.
For example, the maximum target speed in the application is also affected by
these conditions:
• Code/Background Contrast: maximum speed decreases when decreasing
image contrast (poor quality codes, reflective transparent coverings, differ-
ent supports and printing techniques).
• Code Resolution: maximum speed increases when decreasing code resolu-
tion, (i.e. 2X). There is a decrement of overlapping effects between two
adjacent elements.
• Tilt Angle: maximum speed decreases when increasing Tilt angle (from 0 to
45 degrees).

To avoid LED array overheating, for Power Strobed settings, the program automati-
cally limits the range of allowed values for the Exposure Time parameter. Therefore,
after changes to Internal Lighting, recheck Exposure Time.
