•
Channel 5 allows remote access to inputs on remote Slave CellScales
Channel 6
•
Channel 6 is math calculations. Up to 8 separate math channels can be used to combine conversions from
multiple scale channels. Supported functions are: multiply, divide, add, subtract, absolute value, square
root, and constants. Multiple levels of parentheses are available for any scaling or channel data manipula-
tion formulas.
Excitation
•
