ISO/IEC 15415 Symbol Quality Output
Grid Non-Uniformity
Unused ECC
Definition: Grid Non-Uniformity is calculated in accordance with the ISO 15415
specification. The Grid Non-Uniformity grading is defined as follows.
A (4.0) if GN
≤ 038
B (3.0) if GN
≤ 0.50
C (2.0) if GN
≤ 0.63
D (1.0) if GN
≤ 0.75
F (0.0) if GN
> 0.75
When enabled, the Grid Non-Uniformity is attached to the symbol out-
put data as a value.
Serial Cmd: <K725, aperture, overall, contrast, modulation, reflectance margin, fixed
pattern damage, axial non-uniformity, grid non-uniformity, unused
ECC>
Default: Disabled
Options: 0 = Disabled 1 = Enabled
Definition: Unused ECC is calculated in accordance with the ISO 15415 specifica-
tion. The Unused ECC grading is defined as follows.
A (4.0) if UEC
≥ 062
B (3.0) if UEC
≥ 0.50
C (2.0) if UEC
≥ 0.37
D (1.0) if UEC
≥ 0.25
F (0.0) if UEC
< 0.25
When enabled, the Unused ECC is attached to the symbol output data
as a value.
