Reference table for check digit calculation:
Example of check digit calculation modulo 43:
2 out of 5 Industrial The character complement of the 2 out of 5 Industrial code comprises:
– 10 digits: 0 1 2 3 4 5 6 7 8 9
– Start/stop characters: :/; </=
The number of characters is variable.
The start/stop characters are programmed with the characters : and ;. Alter natively, the
characters < and = can be used as start/stop characters.
In the plain text line, the characters . and ; or < and = are printed for start/stop.
The symbol layout is self-checking. A check digit is not required but should be used (modul o
10 with a weighting of 3). The check digit must be programmed in the application.
The ratio of wide to narrow elements should be between 2.0 and 3.0. A ratio of 2.5 is recom-
mended for applications.
The code permits large tolerances between ±15% and 20%.
The blank zone before and after the barcode symbol should be at least 10 times th e width
of a narrow element.
