7.3.2.7 Span calibration by weight
Navigate to menu item 1.2.3.1.
Figure 7-11
1. Enter the mass of the used calibration weight in the field "Calibration weight".
2. Attach this weight with the belt stationary or place it onto the scale.
3. Switch the belt on again and select "Start calibration". The procedure is automatically
terminated following the set number of belt revolutions. The new span digits are then
displayed in the right-hand column as well as the percentage deviation from the
previously used calibration digits (if applicable).
4. Import these values using the "Apply new span digits" button. Commissioning has then
been completed.
Additional parameter settings can also be made, for example:
● Setting of limits for belt load, speed, and material flow rate
● Filter settings
● Parameterization of the inputs/outputs of your weighing module
Further information on these and all other parameters can be found in chapter → Scale
parameters and functions of the belt scale (Page 59).
You can return to the main screen using the "Home" button (house symbol).
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)).
