Bits 0–4: always 0 (B0)
<wwwwww> The and indicate six digits of indicated weight and tare weight with leading zeroes. Valid
characters are W, w, G, g, T, t, N, or n (lower case indicates left justified). W indicates current weight,
G–gross weight, N–net weight, T–tare weight. /P, /S, and /T can be used to specify primary, secondary,
or tertiary units.
Minus (–) indicates sign inclusion; (0) indicates leading zeros. First digit indicates field width in
characters; a decimal point (.) indicates floating decimal point. A decimal with subsequent digit indicates
fixed decimal with n digits to the right of the decimal. Two consecutive decimals (for example, )
send the decimal point even if it falls at the end of the transmitted weight field.
<tttttt> Tare weight. See description above.
is entered at the end of the string as the end of line character in this example.
