T
exp (max)
and
LS
(max)
are represented in the graph below as the curved line for
X
(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 con-
ditions:
•
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,
(i.e.
2X)
. There is a decrement of overlapping effects between two adjacent ele-
ments.
•
Tilt Angle
: maximum speed decreases when increasing Tilt angle (from 0 to 45
degrees).
T
exp (min)
is the minimum Exposure Time value obtainable for the specific application. It
can be evaluated in static reading conditions and depends on the Matrix reader hard-
ware selected for the application (LT-03x lighting system model, optical lens, diaphragm
aperture, reading distance) and on any external lighting system. It may also depend on
code printing quality, and reader position.
The
Internal Lighting
parameter allows setting the operating mode of the internal light-
ing system. The possible values are:
•
Disabled
: the built-in LED array is turned off all the time. This option can be useful
if using an external lighting system;
•
Continuous High-Power
: the internal lighting system is turned on continuously at
the highest power level. This option is useful if the LED-array blinking (Strobed
lighting mode) disturbs the operator.
•
Very High-/High-Power Strobed
: the built-in LED array is on only during the image
exposure time. Different Power Strobed 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, recheck Expo-
sure Time.
