Commands to query weighing data
When the display is turned on, the AD-4212C series outputs the weighing data continuously.
To use the Q or S command, send the C command to stop the continuous data output, then
request the weighing data using the Q or S command.
Command Description
C
Cancels
the
SIR
command.
Q
Requests the weighing data immediately. (Outputs data regardless of the display
condition, stable or unstable. Use this command while the continuous output is stopped.)
S
Requests the weighing data when stabilized. (After the weighing data has stabilized,
outputs the data. Use this command while the continuous output is stopped.)
SIR
Requests the weighing data continuously.
Starts the continuous output of the weighing data. (The C command stops the
continuous output.)
