0
Roll angle of the code center point
INCLINE STATIC INT 40.0 0 Viewing angle
(angle between the axis of the optical read-

CONTRAST_F STATIC CHAR 42.0 .. Symbol contrast as class
(value valid if ≠ ' ')
GROWTH_F STATIC CHAR 43.0 .. Print growth as class
(value valid ≠ ' ')
NONUNIF_F STATIC CHAR 44.0 .. Axial non-uniformity as class
(value valid if not equal to ' ')
ERR_CORR_F STATIC CHAR 45.0 .. Unused error correction
(value valid, if ≠ ' ')
Note:
If a "ReadErr" occurs, the old result data is
retained because no new data is available.
QUALITY_F STATIC CHAR 46.0 .. Overall quality as class
(value valid, if ≠ ' ')
CONTRAST STATIC REAL 48.0 -1.0e+0 Symbol contrast as absolute value
(value valid, if ≠ "-1.0e+0")
GROWTH STATIC REAL 52.0 -1.0e+0 Print growth as absolute value
(value valid, if ≠ "-1.0e+0")
NONUNIF STATIC REAL 56.0 -1.0e+0 Axial non-uniformity as absolute value
(value valid, if ≠ "-1.0e+0")
ERR_CORR STATIC REAL 60.0 -1.0e+0 Unused error correction
(value valid, if ≠ "-1.0e+0")
