Weight (Span) Calibration Commands (With Test Weights)
The instrument calibration can be changed via MODBUS. To carry out this
procedure, the system must be unloaded and the weight value display reset to
zero with the command ‘100’ of the Command Register. Then, a load must be
placed on the system and the correct weight value must be sent to the registers
40037-40038; to save this value, send the control ‘101’ from the Command
Register. If the operation is successfully completed, the two test weight registers
are set to zero.
Analog Output Setting
Write the weight in the registers “Weight value corresponding to the Full Scale of
analog output H” (40045) and “Weight value corresponding to the Full Scale of
analog output L” (40046) or write the weight in the registers “weight value
corresponding to the ZERO of the analog output H” (40043) and “weight value
corresponding to the ZERO of the analog output L” (40044). After writing the
value, send the command 99 from the Command Register to save it to EEPROM
memory.
