12.3 WEIGHT METER 3-BYTE RAM MEMORY DATA (3 Bytes / Item)

All numeric values except scale factor utilize a 2’s complement, 3-byte Hex format, where the
MS byte, Mid byte and LS byte each consist of two Hex nibbles: XX XX XX.

Polarity and decimal point for scale are set by the most significant Hex nibble of the most
significant byte (leftmost byte) as follows:
