8.1.7.28 Module 27: Tape value correction
Description
The tape value correction function can be used to correct the length deviation of the bar code
tape length from the actual tape length (calibration) which results from the production
process. For this purpose, a suitable measuring device must be used to determine the actual
length of one meter of bar code tape (as printed). If, for example, one meter of tape has an
absolute value of 1001.4 millimeters, the value 10014 is entered in the "real length" param-
eter of this module. The real length is specified with a resolution of 0.1 millimeters. To use
the exact resolution, it is useful to measure a longer section of bar code tape and convert
the deviation to a length of one meter.
Figure 8.29:Tape value correction
The "range start" parameter must be configured according to the real starting value of the
used bar code tape. If several different bar code tapes are connected to one another in
sequence, the "range end" of the corrected tape section must also be entered. The entire
bar code tape is corrected with the default value of 10,000,000 for the range end.
