Transaction String
The length of each item in a transition string.
Reading data--6 bytes
Data polarity---1 byte: "-" for negative, and followed the first digit, " " for positive.
Decimal point--1 byte: "."
Measure unit---1-5 bytes: "Ib", "kg", "Ib:oz", "pcs", "%". Units are always lower case, left aligned.
Current status--4 bytes
If the weight is over capacity, the scale will return eight "^" characters (the field of polarity, decimal
point, weight data is filled by "^").
If the weight is under capacity, it will return eight "_" characters (the field of polarity, decimal point,
weight data is filled by "_").
If the zero point is error, it will return eight "-" characters (the field of polarity, decimal point, and
weight data is filled by "-").
Useless leading 0 before digits is suppressed. Reading weight is right aligned.
