You can improve the results for your system even further following completion of the
calibration or also during subsequent operation by means of a flow correction by material
test ( → Determination of a correction factor (Page 57)).
7.3.2.9 Span by material batch
With this type of calibration, a previously or subsequently weighed amount of material is
conveyed over the scale. The span is subsequently calculated according to the amount of
material.
Prerequisites are a successful calibration of the speed and a zero calibration.
Navigate in the span calibration menu to item "1.2.3.3 Span by material batch".

1. If you wish to convey a known amount of material, enter this in the "Conveyed amount of
material" field.
Alternatively you can also enter the amount of material following conveyance.
2. Make sure that the belt is running and empty.
3. Start the calibration procedure using "Start calibration". Allow the material to be conveyed
on the belt.
4. When the complete amount of material has passed the scale and the belt is empty again,
terminate the procedure using "Stop calibration".
Enter the amount of material in the "Conveyed amount of material" field if it has not yet
been recorded. To do this, weigh the conveyed amount of material on a separate scale.
5. Start the required calculations using the "Calculate new span digits" button. The
calculated calibration weight and the calculated span digits are displayed.
6. Import the values using "Apply new span digits". Commissioning has then been
completed.
