◎The stock function is available only after stable indication appears and there
should be a weight or quantity value.
◎Remove the item and the display goes back to zero before the next stock
action can register.

Appendix
Barcode category instruction
Code39:
a barcode symbology that can encode uppercase letters (A through Z), digits (0
through 9) and 8 special characters. Possibly the most serious drawback of Code 39 is its low
data density: It requires more space to encode data. This means that very small goods cannot
be labeled with a Code 39 based barcode. However, Code 39 is still widely used and can be
decoded with virtually any barcode reader. One advantage of Code 39 is that since there is no
need to generate a check digit, it can easily be integrated into existing printing system by
adding a barcode font to the system or printer and then printing the raw data in that font.
Code93:
a barcode symbology designed in 1982 by Intermec to provide a higher density
and data security enhancement to Code 39. It is an alphanumeric, variable length symbology.
Code 93 is used primarily by Canada Post to encode supplementary delivery information.
Every symbol includes two check characters.
Code128:
a very high-density barcode symbology. (A special version of it called GS1-128
is used extensively worldwide in shipping and packaging industries.) It is used for
alphanumeric or numeric-only barcodes. It can encode all 128 characters of ASCII and, by
use of an extension character (FNC4), the Latin-1 characters defined in ISO/IEC 8859-1.
GS1-128 (formerly known as UCC/EAN-128), not Code 128, is the major component of the
