AutoControl
Module 16
The module defines the mode of operation of the function AutoControl. The function moni-
tors the quality of the decoded barcodes and compares these with a limit value. If the limit
is reached, a status signal is set.

Mode
The parameter defines the evaluation base of the Auto-
Control function. Depending on the setting, either the
label quality or the decoding quality can be used as cri-
teria for the reading quality.
The label quality is the ratio between the scans which
have collected information for the decoding, and the
number of scans which were necessary to decode the
entire barcode.
Label quality =
The decoding quality is computed as follows: ratio
between the identical scans and the number of scans
which were necessary to decode the entire barcode.

0: Off
1: Label quality

quality
The parameter defines a threshold value for the average
of the reading quality. If the value is not reached, a
warning is generated.

Sensitivity
With this parameter the insensitivity towards changes in
the reading ability can be specified. The higher the
value, the less influence a change of reading ability has
on the floating average.
