Minimum number of digits to be read for ITF, STF, or Codabar (MINIMUM
DIGITS)
You may set the minimum number of digits to be read for ITF, STF, and Codabar.
Setting a small number of digits increases the frequency of digit-missing reading or
misreading depending upon how to scan bar codes or the quality of bar codes. On the
other hand, setting a large number will diminish the possibility of those errors.
The setting range is from 2 to 20 for ITF, from 1 to 20 for STF, and from 3 to 20 for
Codabar. The default is 4 for ITF and Codabar, and 2 for STF.
