8.3.6
Minimum weighing range
The weight value can only be used above the minimum weighing range for legal trade
registration with the specified scale interval. The minimum weighing range in the unit "d"
(scale interval) is defined during calibration/official verification.
The factory setting is 0 d. 20 d is generally entered for legal trade scales.
8.3.7
Maximum weighing range
For purposes requiring official calibration, the weight can only be used with the defined scale
interval below the maximum weight (+ 9 d, d = scale interval). The maximum weight is
defined during commissioning.
The maximum weight depends on the number and type of load cells used.
8.3.8
Calibration weights 0, 1, 2 and calibration digits 0, 1, 2
The calibration weights and corresponding calibration digits define the characteristic curve of
the scales. A detailed description can be found in section Calibration procedure (Page 77).
8.3.9
Scale interval
The scale interval for the weighing range can be defined in accordance with EN 45501
(0.0001 to 50).
8.3.10
Zero by power-on
The scales can automatically be set to zero when the supply voltage is switched on (in legal
trade operation, this is at the end of the startup waiting time). A weight of ±10 % of the
maximum measuring range can be set to zero by power-on for legal trade scales.
NOTICE
If the scales are not being used in legal trade operation (no OIML restrictions), fully loaded
scales can also be set to zero once this function is enabled. The function can, however, be
limited by setting a maximum and minimum weight for zero by power-on. See the section
on maximum and minimum weights for zero by power-on.
