Set Stacked Code
Code Score Enable: If it is enabled, the client software will evaluate the code reading
environment for stacked code and output code score.
9.4.4 Set Code Quality Evaluation
The code quality evaluation function judges the quality of codes and outputs overall grade.
Currently, only 1D code and 2D code support code quality evaluation.
Note
● The function of code quality evaluation may differ by device models.
● In test operation mode, this function is enabled by default. In normal mode, you need to
enable it manually.
Set 1D Code Quality Evaluation
The 1D quality evaluation function uses the ISO15416 standard to judges the quality of
codes and outputs overall grade. Currently, this function is only applicable to Code 39 and
Code 128.
Steps
1. Go to Algorithm Control → Algorithm Parameter, and select 1D Code as Arithmetic Type.
2. Enable 1D Code Quality Evaluation.
3. Enable different quality evaluation standards according to actual demands.

Parameter
Description
Decodability
It evaluates whether the code has enough basic information to be
decoded.
Symbol Contrast
It evaluates the difference between the max. brightness value and
the min. brightness value of the code area.
Modulation
It evaluates the degree of change in terms of brightness.
Edge Determination
It evaluates how well the number of edges read by the code matches
the configured number of edges.
Minimum Reflectance
It evaluates the ratio of the min. brightness value to the max.
brightness value.
Minimum Edge Contrast
It evaluates the min. value of the reflectivity difference of the strip
connecting the spaces.
Decode Enable
It evaluates whether the code recognition is successful or not.
Defects
It evaluates codes or spaces for defects or dirts.
