Adjusting the bar code scanner
To completely adjust the bar code scanner, the electrical installation must be complete and
the device must be operated, see
chapter 6 Electrical installation, page 51
Startup and configuration, page 65
1. Align the bar code scanner in such a way that the angle between the scanning line and
the bar code's lines is almost 90°.
2. To avoid disruptive reflections, rotate the bar code scanner from the plumb line so that
the emitting light meets the bar code at an angle of approx. 105° (line scanner),
chapter 5.3.4 Avoiding surface reflections, page 46
.
3. Manually bring objects with bar codes sequentially into the bar code scanner's visual
range. The default setting of the focal position is 285 mm (11.2 in) from the reading
window. Check the reading result using the SOPAS-ET configuration software.
Move objects in different positions (angles) to the reading area and ensure that the
thresholds of the permitted reading angles are not exceeded.
4. Align the bar code scanner in such a way that the good read rate is between 70 and
100%.
5. Tighten the screws on the bar code scanner.
The bar code scanner is aligned with the bar code.
