8.7.1 Effective tare weight - from specification
A tare weight can be specified in data record DR 15. You activate the specified tare weight with
a command (see command 1013). From this point on, the activated tare weight is factored into
the weight calculations. The "Delete tare" command deactivates the active tare weight. This
does not delete the specification in data record DR 15.
8.7.2 Effective tare weight (semi-automatic)
The corresponding command (see command 1011) applies the current gross weight as the
active tare weight. From this point on, the activated tare weight is factored into the weight
calculations. The "Delete tare" command deactivates the active tare weight.
8.7.3 Zero weight (semi-automatic)
The zero weight command (see command 1001) entered by the user sets the current gross
weight to "Zero" provided it is within the defined zero setting limits. The current gross weight is
saved as the zero weight. The zeroing weight must be within the specified range (usually +3 /
‑1 % of the set zero point).
