The Internal Lighting Mode parameter allows to set the operating mode of the internal
lighting system. The possible values are:
Disabled : the built-in lighting system is turned off all the time. This option can be useful
only if external lighting is sufficient;
Always ON : the built-in lighting system is turned on all the time at the lowest power level.
This option is useful if the lighting system blinking (Strobed operating mode) disturbs the
operator.
Very High/High/Medium-Power Strobed : the built-in lighting system is on only during the
image exposure time. Three different lighting levels can be set.
NOTE
To avoid LED array overheating, for Power Strobed settings, the program
automatically limits the range of allowed values for the
Exposure Time
parameter. Therefore, after changes to Internal Lighting Mode, recheck
Exposure Time .
CAUTION:
The maximum target speed in the application is affected by these conditions:
Code/Background Contrast : maximum speed decreases when decreasing image
contrast (poor quality codes, reflective transparent coverings, different supports and
printing techniques).
Code Resolution : maximum speed increases when decreasing code resolution (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).
