POSITIONING
The VB14 scanner is able to decode barcode labels at a variety of angles, however
significant angular distortion may degrade reading performance.
When mounting the VB14 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 12.1. Position the
reader in order to
minimize
the
Pitch
angle.
Figure 11.1 Pitch angle
The
Skew
angle is represented by the
value
S
in figure 12.2. Position the
reader to
assure at least 10°
for the
Skew
angle. This avoids the direct
reflection of the laser light emitted by
the VB14.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.

The
Tilt
angle is represented by the
value
T
in figure 12.4. Position the
reader in order to
minimize
the
Tilt
angle.
