All comparison criteria are AND linked; this means all active comparisons must be fulfilled before the just-
decoded bar code can be identified as already decoded and then deleted.

Description
If this criterion has been activated,
the bar code content is used to
determine whether the bar codes
are identical.
If this criterion has been activated,
the bar code direction is used to
determine whether the bar codes
are identical.
If this parameter is not equal to 0,
the bar code position in the scan-
ning beam is used to determine
whether identical bar codes have
already been decoded. In this
case, a +/- bandwidth must be
specified in 1/10 degrees, within
which the same bar code is per-
mitted to be in the scanning
beam.
If this parameter is not equal to 0,
the decoding time (time at which
the bar code was decoded) is
used to determine whether identi-
cal bar codes have already been
detected. For this purpose, a time
difference in milliseconds is speci-
fied. It ensures that identical bar
codes can only occur within this
time.
