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.
