3.1.2Tilt 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:

3.2LINEAR 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.
