Data Format
By changing the function settings on the main unit of the balance, users can select either a six-digit numeric format or a seven-
digit numeric format.
1. Six-digit numeric format is composed of 14 characters, including the terminators CR=0DH, LF=0AH.
2. Seven-digit numeric format is composed of 15 characters, including the terminators CR=0DH, LF=0AH. A parity bit
can also be appended.
