READING FEATURES

3.1.2 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:

ACB angle

0.33 18° 30°

0.25 14° 23°

0.125 7° 11°

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.
