Parameter assignment/addressing
6.5 DR03 Calibration parameters
The maximum number of legal-for-trade scale intervals depends on the load cells used (e.g.
6000d with C6 load cells or 3000d with C3 load cells) and may not be exceeded in any of the
set ranges in the case of legal-for-trade scales. Only when OIML is set in DR03.
Multi-interval scales
Single-range scales can be set as multi-interval scales with two or three different weighing
ranges or scale intervals.
Example
Triple-division scales with:
Weighing range 1: 10 kg – 1500 kg / 0.5 kg
Weighing range 2: 1500 kg – 3000 kg / 1.0 kg
Weighing range 3: 3000 kg – 6000 kg / 2.0 kg
The weighing range and the corresponding scale interval is automatically changed depending
on the load applied both during loading and unloading.
After taring, the net weight of the scales is displayed with the scale interval of the smallest
weighing range, so that low weights can also be recorded with maximum precision with already
loaded scales. The maximum tare value is limited to the maximum load of the smallest weighing
range.
When defining a multi-interval scale, the individual ranges must seamlessly connect to one
another:
Min2 = Max1; Min3 = Max2
6.5.8 Calibration weights 0, 1, 2, 3, 4 [calibrationWeight] and calibration digits
[calibrationDigit] 0, 1, 2, 3, 4
The calibration weights with the associated calibration digits define the scale characteristic.
The calibration weights must be specified in ascending order. Normally, it is enough to calibrate
the scale with two calibration points. Setting further calibration points is therefore optional.
Typically, calibration weight 0 = 0, because the calibration point 0 is normally set with the scale
empty.
If a scale has been modified and the current content is known, this value can be entered and
set as the calibration weight. A larger calibration weight 1 is then specified and set.
The calibration weights must be at least 5% of the nominal load of the scale and must differ from
one another by an amount of at least 5% of the nominal load:
● Calibration weight 0 = 0 kg
● Calibration weight 1 = at least 5% of the nominal load of the scale
● Calibration weight 2 = at least 10% of the nominal load of the scale
The calibration digits are determined automatically by the calibration commands and assigned
to the respective calibration weights. Therefore, the calibration digits do not have to be
specified.
