Note
To increase reading performance, we recommend only permitting symbol sizes which
are actually relevant for evaluation.
¾
If codes with between one and five different symbol sizes are to be read, click the
F
IXED
radio button.
¾
Select the individual symbol sizes in the drop-down lists of the input fields in the F
IXED
SYMBOL
SIZE
group.
Permitted error correction:
In the default setting, 100 %, the ICR can use all additional error-correction data bytes
(ECC data) available in the code without limitations as an aid when decoding. The
number of data bytes actually used is thereby a standard for code quality (code print,
compliance with tolerances etc.). The quality is higher as the number of used error-
correction bytes decreases. The ICR outputs this number in its absolute form as well as
in a percentage ratio to the number of error-correction data bytes available in the code.
This information is part of the reading diagnosis data “EC“ in the reading result of the
auxiliary interface (
).
¾
Reduce the permissible error correction incrementally for higher code quality.
Ensure that reading remains successful.
Note
If the error correction exceeds the permissible percentage when reading a code, the
code receives the ST=5 error status. In the default setting, it is output in the reading
diagnosis via the auxiliary interface instead of the host interface.

When objects are conveyed in a consistent manner and the code is in the same
position on the objects, you can reduce the image memory area to be evaluated by
entering the relevant percentage values in the I
