point, force data is filled by “^”).
25.4.3 If the force is under capacity, it will return eight “_” characters (the field of polarity, decimal point, and
force data is filled by “_”).
25.4.4 If the zero point is error, it will return eight “-“ characters (the field of polarity, decimal point, and force
data is filled by “-”).
25.4.5 Useless leading 0 before digits is suppressed. Reading weight is right aligned.
