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 barcode
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 metre of barcode tape (as printed). If, for example, one metre of tape has an
absolute value of 1001.4 millimetres, 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 millimetres. To use
the exact resolution, it is useful to measure a longer section of barcode tape and convert the
deviation to a length of one metre.

Figure 8.29: Tape value correction
The "range start" parameter must be configured according to the real starting value of the
used barcode tape. If several different barcode tapes are connected to one another in
sequence, the "range end" of the corrected tape section must also be entered. The entire
barcode tape is corrected with the default value of 10'000'000 for the range end.
