Unused Error Correction
ODV-2D > Grading > Unused Error Corr.
Unused Error Correction is a measurement of the amount of margin availa-
ble to recover damage using error correction. Low unused error correction is
usually due to regional or spot damage in the code.
The ODV-2D will fail any barcode with an unused error correction at or below
the value set in this menu, regardless of overall grade.

Codeword Yield
ODV-2D > Grading > Codeword Yield
Codeword yield is a measurement of the number of validly decoded code
words expressed as a percentage of the maximum number of code words
that could have been decoded. The amount of margin available to recover
damage using error correction. Low codeword yield may indicate a y-axis
failure in the barcode such as thermal drag.
The ODV-2D will fail any barcode with a codeword yield at or below the value
set in this menu, regardless of overall grade.

Global Threshold
ODV-2D > Grading > Global Threshold
This menu sets the threshold used by ODV-2D to interpret a scan reflec-
tance profile into bars and spaces. Reflectance profile values above the
Global Threshold are spaces and values below the threshold are bars. The
Global Threshold will set the bar/space transition point between the highest
(Rmax) and lowest (Rmin) reflectance of a scan profile. The bar/space
transition point formula is: Rmin + (Rmax
–
Rmin) * (Global Threshold) / 100.
