Adjusting the reader
The VB34 reader is able to read labels at most angles, however, a strong distortion
can have an unfavourable effect on reading performance.
When assembling the VB34, note the following three ideal angles for the label
position:
Tilt angle 0°, angle of rotation 10° to 30° and rotation 0°.
Follow the proposals in the next paragraph how best to position the reader:
The tilt angle is represented by the value P, see figure 41. Adjust the reader in such
a way that the tilt angle is held as low as possible.
