3.Communication Data Format (RS-232C continuous transmitting)
The communication address X = 0 in continuous transmitting and the format is
=,X1,X2,X3,X4,X5,X6. The transmitting X1,X2,X3,X4,X5,X6 is displaying data, and “ = ”is the list
separator.
Example: weight: 100.00kg, transmitting: = 00.001 =00.001.
