“Z”
- This command is sent to the scale to zero the scale. The scale will disregard
this command if the scale is in motion, positive overload or negative
overload. The scale will also disregard this command if it is not in gross mode
or within the zero reset range. Even if successful, the host receives no
response from the scale. The host must issue a “P” command to determine if
the command was processed by the scale.
“T”
- This command is sent to the scale to tare the scale. The scale will disregard
this command if the scale is in motion, positive overload or negative
overload. The scale will also disregard this command if it displaying a
negative gross value. Even if successful, the host receives no response from
the scale. The host must issue a “P” command to determine if the command
was processed by the scale.
“G”
- This command is sent to the scale to revert to gross mode. The scale will
disregard this command if the scale is in motion, positive overload or
negative overload. The scale will also disregard this command if it is not in
net mode. Even if successful, the host receives no response from the scale.
The host must issue a “P” command to determine if the command was
processed by the scale.
“N”
- This command is sent to the scale to revert to net. The scale will disregard
this command if the scale is in motion, positive overload or negative
overload. The scale will also disregard this command if it is not in gross mode
or a tare has yet to be established. Even if successful, the host receives no
response from the scale. The host must issue a “P” command to determine if
the command was processed by the scale.
“C”
- This command is sent to the scale to toggle among the configured units. Even
if successful, the host receives no response from the scale. The host must
issue a “P” command to determine if the command was processed by the
scale.

Figure B-10 shows the weigh data / status record automatically transmitted by the scale at
the end of each display update. The same host commands listed in Section B.1.6.1 are
accepted and acted upon by the scale.
