Note 1: The data format consists of (header code), minus/plus sigh, numeric data and
decimal data. If weight data is minus, -(2DH) is added after header data. If weight is
plus data, 0(30H) is output.
Note 2: The data is aligned form right except plus/minus sign if weight data are less then 5
digits.
Note 3: When weight is over the capacity, the following data is output:
