Ensure that the difference between two adjustment weights is at least 5% of the
measurement range.
The adjustment consists of the following steps:
Define adjustment weights and other parameters of the DR 3 data record.
Send DR 3 to the scale
With an empty scale, give the command "Valid adjustment weight = 0"
Load the scale with the defined calibration weight
Give the command "Valid adjustment weight = 1"
Receive DR 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) produces 5 800 000 digits
Adjustment weight 1 = 100 kg produces 10 100 000 digits
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 maximum value for adjustment digits is 15 379 113 and the value for
completely empty load cells (without the weight of the construction itself) is
1 398 101 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 of the scale.
