Operating instructions

Basic information on data interchange with the balance
The balance receives commands from the system and acknowledges the command with an appropriate
response.
Command formats
Commands sent to the balance comprise one or more characters of the ASCII character set. Here, the following
must be noted:
●
Enter commands only in uppercase.
●
The possible parameters of the command must be separated from one another and from the command
name by a space (ASCII 32 dec., in this description represented as ).
●
The possible input for "text" is a sequence of characters of the 8-bit ASCII character set from 32 dec to 255
dec.
●
Each command must be closed by C
R
L
F
(ASCII 13 dec., 10 dec.). The characters C
R
L
F
, which can be
inputted using the Enter or Return key of most entry keypads, are not listed in this description, but it is
essential they be included for communication with the balance.
Example
S – Send stable weight value
Command S Get the current stable net weight value.
Response S S WeightValue Unit Current stable weight value in unit actually set
under unit 1.
S I Command not executable (balance is currently
executing another command, e.g. taring, or
timeout as stability was not reached).
S + Balance in overload range.
S - Balance in underload range.
Example
Command S Query a stable weight value.
Response S S 100.00 g The current stable weight value is 100.00 g.
The available MT-SICS commands are listed in the table (depending on the model). For further information
