bridge enabled.
WRITING EXAMPLES
To write the set-up parameters following the example:
In the bytes 1-2 (Command Register) write value Hex 3FFF. This value opens the writing area of the
DAT 11.
Example: to change the default values of the DAT 11 like the Capacity of the load cells, the Sensitivity
and Division value to 15000, 2.9965 and 2:
Capacity Byte 17 Byte 18 Byte 19 Byte 20
Hex 00 00 3A 98
Dec 15000
Sensitivity Byte 21 Byte 22
Hex 75 0D
Dec 29965
Division Byte 23 Byte 24
Hex 00 0D
Dec 13
Save the data by writing the value Hex 7 in Command Register.
N.B. The DAT 11 does not accept writing of the same values already written.
To perform Zero and FS Calibration it is not needed to abilitate the internal Writing Area of the DAT 11.
Zero Calibration:
Whit empty system put Hex 4 in Command Register (bytes 1-2). The new Zero value is stored.
Full Scale Calibration:
Put a know weight on the system and write its value in the Data Register (from byte 3 to 6). Put value
Hex 5 in Command Register. The weight value will be displayed.
