8.3.16 Maximum tare load
The parameter is specified as a percentage of the "Maximum weight" parameter. All tare
values (semi-automatic, automatic, or preset tare) are checked for this limit and rejected if
the limit is exceeded.
8.3.17 Maximum negative zero setting limit (power-on)
Initial zeroing means the scale is automatically set to zero when the supply voltage is
switched on.
If initial zeroing (zero setting at switch-on of the supply voltage) has been activated, the
effect of the function can be limited with this parameter. The parameter is specified as a
percentage of the "Maximum weight" parameter.
Example:
Maximum weight = 100 kg
Negative zeroing limit (initial zeroing) = 10%
→ Up to -10 kg (10% of 100 kg) can be zeroed by the initial zeroing function.
8.3.18 Maximum positive zero setting limit (power-on)
Initial zeroing means the scale is automatically set to zero when the supply voltage is
switched on.
If initial zeroing (zero setting at switch-on of the supply voltage) has been activated, the
effect of the function can be limited with this parameter. The parameter is specified as a
percentage of the "Maximum weight" parameter.
Example:
Maximum weight = 100 kg
Positive zeroing limit (initial zeroing) = 10%
→ Up to 10 kg (10% of 100 kg) can be zeroed by the initial zeroing function.
8.3.19 Maximum negative zero setting limit (semi-automatically)
Zero setting defines the current weight of the scale as zero weight.
For the zero setting (semi-automatic, automatic and tracking), the effect of the function can
be limited by specifying limits. The reference point for the effect of the limitation is not the
current gross weight but rather the weight that the scale would have displayed had it not
been set to zero beforehand (zero point at time of scale calibration).
For scales in operation where official calibration is required, the limitation between the
negative and positive weight for the zeroing is 4% of the weighing range.
Example:
Maximum weight = 100 kg
Negative zeroing limit (semi-automatic) = 3%
→ Up to 3 kg (3% of 100 kg) can be set to zero by the zero setting function.
