Codabar Character Correlation
When correlation is enabled, the barcode reader will combine label data from multiple scans
when decoding. Enabling correlation will help the scanner read labels that have some spots and/
or voids. It may also help read labels that have damaged areas. Enabling correlation will also
increase the chances that a label will be read incorrectly.
