Quality Counters
When checked, the Quality Counters parameter activates a counter handled event, which counts the good decodes
during the reading phase. If no stop reading phase event occurs, the reading phase is stopped at 100 good decodes.
This parameter is independent from the Decoding Safety parameter.
The value reached by the counter is transmitted in a fixed 3-digit format in the Info Field.
For Multilabel Code Combinations the counter increments for each good decode on each label in the reading phase.
Quality counters are not valid for code Reconstruction Reading Mode or for readers in a Synchronized network (Master
or Slaves).
Continuous
The reading phase is always active and, differently from the Automatic operating mode, it also allows reading two or
more codes when placed along the same scan line.
Code transmission is identical to the other operating modes except that there is no transmission on the serial port in
case of a No Read condition.
For details about the conditions to use this operating mode see the Operating Mode Reference Table.
Continuous Threshold
The Continuous Threshold sets an N number of scans without a code in order to accept same code consecutive
reading. This threshold does not apply to different code consecutive reading.

Code Filter Depth
For a description of Code Filter Depth in Automatic mode click here.
In Continuous mode, Code Filter Depth is used to avoid multiple reads of the same code. The selected value (other
than zero) defines the number of codes to memorize in a FIFO list.
When a code is read, it is compared to the list. The application program inherently compares codes based on content
and code length. If the list contains a code identical to the current code being read, the current code is discarded. If
not, the current code is accepted and added to the list in the first position; the remaining codes in the list are shifted.
If the list is full the oldest code in the list will be flushed.
When = 0, there is no FIFO list and there is no filtering.
