6.4 Positioning
The VB14A scanner is able to decode barcode labels at a variety of angles, however
significant angular distortion may degrade reading performance.
When mounting the VB14A take into consideration these three ideal label position
angles:
Pitch 0°, Skew 10° to 30° and Tilt 0°.
Follow the suggestions for the best orientation:
The Pitch angle is represented by the
value P in figure 6.21. Position the
reader in order to minimize the Pitch
angle.
Figure 6.18 Pitch angle
The Skew angle is represented by the
value S in figure 6.22. Position the
reader to assure at least 10° for the
Skew angle. This avoids the direct
reflection of the laser light emitted by
the VB14A.For the raster version, this
angle refers to the most inclined or
external raster line, so that all other
raster lines assure more than 10°
Skew.
Figure 6.19 Skew angle
The Tilt angle is represented by the
value T in figure 6.24. Position the
reader in order to minimize the Tilt
angle.
By using the ACB (Advanced Code
Builder) software parameter, the tilt
angle is less critical and can be
decoded even if the scan see section
6.18 or the Help On Line for details.
