5.7.9.1
General
Reading processes such as the number of necessary multireads, regulations for dealing
with the start and stop characters, or check digit tests are configured under the
group.
5.7.9.1.1
Multiread
You use the
parameter to define a minimum number of G
OOD
R
EAD
required for a
reading to be output as a G
OOD
R
EAD
.
By defining a minimum number of readings, you reduce the likelihood of misinterpretations
for codes with poor printing quality or a low contrast, and increase reading reliability.
5.7.9.1.2
Check digit test
parameter is used to define the calculation method for the plausibility
check on the code contents. A check digit is calculated from the code contents and compa-
red with the check digit in the code. The selected method must match the method used du-
ring creation of the code. If the calculated check digit matches the check digit in the code,
the reading is regarded as a G
OOD
R
EAD
).
Check digits prevent misinterpretations and increase reading reliability. The use of a
check digit is recommended for this code type.

Codes with a defined number of characters can be excluded from the reading process via
the parameters in the
Limiting the number of codes to be read reduces the decoding time.
