Tilt Angle Improvement with ACB
ACB allows barcode reading with an increased tilt angle. The tilt angle depends upon
the code aspect ratio defined as H/L according to the table below:

3.2 LINEAR CODE READING
The number of scans performed on the code by the DS1500 and therefore the
decoding capability is influenced by the following parameters:
•
number of scans per second
•
code motion speed
•
label dimensions
•
scan direction with respect to code motion
At least 5 scans during the code passage should be allowed to ensure a successful
read.
