8.2.12. ZR Zero Range
[ SDO 2300 sub 11 ]
Sets the zero range manually
– this is the range in increments within which the weighing scale can be zeroed.
Issuing the ZR command without any parameter will return the current value. Permitted values are between the
lower limit of 0 (= factory default setting) and the upper limit of 999999. A value of zero enables the standard
zero range of +/-2% of max.

8.2.13. ZI
Initial Zero Range
[ SDO 2300 sub 10 ]
Define the initial zero range (0...999999 d). If ZI is non-zero the device will perform an automatic Set-Zero when
the weight stabilizes with the No-motion settings and the weight is within the ZI range. Factory default: 0.

8.2.15. TN Set / Clear Non-Volatile Tare
[ SDO 2300 sub 13 ]
This command sets the tare mode to volatile or non-volatile. Value range is 0 or 1; Factory default is 0 (volatile).
If set to 1 (non-volatile), every set/clear tare will write the value directly to the EEPROM.
