0…1

0 = Net weight, 1 = Gross weight, 2 = Peak

2

0 = N.O. 1 = N:C.

3

0 = Positive values 1 = Negative values

4

0 = Always controlled 1 = Only with stable weight

EXAMPLE: CALIBRATION FUNCTION VIA MODBUS

To perform the calibration of full scale (that require the weight value in the sample set in the data register), 

the value in the data register must be present when the command register is programmed. For example:
Calibrate the full scale using a sample weight of 2000 kg.
Write 2000 in the data register.
Write 0x0011 in the command register.
Use the multiple registers write function and write the registers of data register and command register 

in a single command.
