4.3 - Code Readability Index

The Readability Index provides a measurement of a specic symbol’s ease or difculty to be decoded by the CR2500. The

Readability Index is specic to the CR2500, and should not be confused with a verication quality measurement.

The Readability Index is a blend of information obtained from the internal operations of the decoding algorithm pertaining

to contrast, symbology construct, error detection, forward error correction (if applicable), and other symbology-specic

characteristics.

The Readability Index is a score on a scale of 01 (very poor) to 100 (very readable). Due to differences based on motion,

skew, reection, focus, and ambient lighting, the Readability Index on the same symbol may vary somewhat from read

to read. However, a poor contrast or damaged symbol will score lower than a high contrast undamaged symbol. The

Readability Index can be used as a quick check on the reliability of label generation or marking systems. When used in

conjunction with the CR2500 stand (or xed mount positioning) which xes the distance from the reader to the symbol, and

constant ambient light, the Readability Index provides a symbol quality assurance tool and check point for feedback to an

overall label or marking quality control system.

The Readability Index is enabled by rst reading a CodeXML® rule into the permanent CR2500 Memory:

Each time a data symbol is read, the index will be output, followed by a comma, (,) followed

by the decoded data. The reader will store the rule and reset, but will not output the

Readability Index until the Readability Index Output Enable code is read. The Reader will

continue to output the Readability Index upon every read until disabled, either by reset or by

reading the Readability Index Output Disable code.
