Scale parameters and functions
8.4 DR 3 calibration parameters
8.4.8
Decimal places for process values
This parameter is used to specify the number of decimal places to which the process values are
to be rounded. This value decouples the main display of the weight values from the values used
in the control software.
8.4.9
Maximum tare load
The weighing module accepts any external tare specification which is less than the maximum
tare load (percentage of maximum weighing range). Tare commands are also accepted
provided that the current gross weight is less than the configured maximum tare load.
8.4.10
Maximum negative zeroing limit
Zeroing defines the current weight of the scales as zero.
You can limit the effect of the zeroing function. The limitation is based not on the current gross
weight, but rather on the weight which the scales would display had there been no zeroing (time
of scale calibration).
8.4.11
Maximum positive zeroing limit
You can limit the effect of the zeroing function. The limitation is based not on the current weight,
but rather on the weight which the scales would display had there been no zeroing (time of scale
calibration).
8.4.12
Standstill range
Standstill monitoring checks whether the scales are correctly balanced. Scale standstill is
registered if the weight changes by less than a specified fluctuation in d (standstill value) over
a specified time (standstill time). Standstill monitoring is used in static scale mode (commands:
zeroing, taring). The diagram below illustrates how standstill monitoring works.
The current weight can only be registered in legal trade applications if standstill is reached.
