5.4.5.7 Setting Range With Multi-Range Scale

The setting of parameter 'Type' (=Scale Type; see Menu Item '442:Mode') defines if
your scale operates as multi-range or multi-divisional scale. Calibrate multi-range or
multi-divisional scale in the exact same way as you are accustomed to doing with a
standard scale.
Please note that the range calibration uses the range with the highest full scale value.
Partial ranges are not calibrated. Deviations can be corrected by linearization.

5.4.5.8 Fct. 4452:Linearization

The linearization function permits the scale characteristic to be corrected in three
spectrum points (25%, 50%, 75% of full scale value) by up to ± 9.9 increments.
Before performing linearization, calibrate scale dead weight and
range.
Determining characteristic
Determine characteristic deviation in each spectrum point and enter value.
•
Apply 25% of range as calibration weight.
•
Read actual weight and note value.
•
Calculate correction value in increments (increment e stands topleft on
display) using this formula:
Correction value = (Setpoint - actual weight) / Increment value
(with multi-divisional/multi-range scales, increment value of big range)
•
Enter correction value in increments at menu item '4452:Linearization'.
•
Check deviation. If necessary, repeat.
Resume from next spectrum point (50 %, 75 %).
Example
You have a scale with 600 kg weighing range and 0.2 kg increment value (i.e. with
3000 increments).
Upon linearization, scale at spectrum point 50 % (= 300 kg) shows a value of 300.28.
To linearize scale, calculate correction value in increments (not in kg) using above
formula and enter value:
Correction value = (300.00kg - 300.28kg) / 0.2kg = -0.28 / 0.2 = -1.4
The correction value to be entered is -1.4.
