SZ This command sets a new “current zero” which is then the basis of all weight values until further updated by the zero tracking function, another SZ command or the “reset zero” command RZ.
The SZ responds with OK or ERR. The SZ succeeds if the new zero is within the Zero range and the weight is stable.
Devices implementing the ZR (Zero Range) defines the range, else the range is 2% of the CM value.

The SZ command will fail (Unit responds with ERR) if the new “current zero” is more than ZR or 2% (of the CM value) higher or lower than the “true zero” set during calibration. The SZ command will also fail if the weight signal is not stable as defined by the No motion range (NR) and the No motion time (NT). If the weight signal is “stable”, the response to the IS command (Device Status) will show the “signal stable” bit active and the SZ command will be accepted (OK). If the “signal stable” bit is not active, the SZ command will be rejected and the Unit will respond with ERR (error).

Note: The LDM allows 20% on the first SZ after power ON.
