Note
If reading from the front, mount the CLX above the conveyor belt in such a way against the
conveying direction that the scan line hits the object under a skew of approx. 10
°
.

Count direction of the reading angle RA
Explanation
The CLX can scan and decode several bar codes with each read. In doing so, it determines
the specific local reading diagnosis data for each bar code the reading angle (RA value) of
the center of the bar code within the scan.
shows the count direction of the reading angle. The count direction of the reading
angle is marked by a cross in the reading window.
By determining this data, the device can separate identical bar codes.
Tip
In the default setting, the CLX does not output the "RA" value in the reading result on the
host interface. If this is required to evaluate the result in the host, the values can be included
in the "Code-Info/Separator" block of the output string using the "CLV-Setup" program.
