NOTE
Optimal results are achieved when the scan line is tilted about 13° relative to the verti‐
cal. The version with a side reading window therefore features a light emission angle of
103°.

Counting direction of the reading angle and the code angle
The device can scan and decode several bar codes at each reading.
At the same time, the location-specific reading diagnostics data are determined for
each of them:
■
The reading angle, starting from the reading window, at which the device detects
the bar code center on the red scanning line of the deflected scanning beam can
be output as an RA (reading angle) value.
By determining the RA value, identical bar codes (code type, code length, and data con‐
tent) can be separated, and the bar code data assigned based on their position on the
object. 1 RA corresponds to about 0.71° (50 RAs correspond to 35.4°, 100 RAs corre‐
spond to an aperture angle of 70.8°).
