Weighing Functions
Load the scale with the defined adjustment weight
Give the command "Valid adjustment weight = 1"
Receive DS 3 from the scale
Save the data to a data carrier
The adjustment sequence for the increasing adjustment weights must be retained.
Example:
Zero point = 0.0 kg (always)
Adjustment weight 1 = 100 kg
This defines the characteristic curve (0 is entered as the weight value for further
adjustment weights) and the scale can now perform the calculations for the weight
values over the entire measurement range.
Note:
Since the theoretical maximum value for adjustment digits is 60074 and the value
for completely empty load cells (without the weight of the construction itself) is
5461, the plausibility of the characteristic curve can be roughly estimated, to
determine load deviations for example.
The illustration shows the relationship between the adjustment digits and the
adjustment weight.
