Step 2
1. A specific quantity of material is now conveyed by the belt.
Before the material reaches the scale, activate the command "Start span calibration with
material batch" (67).
2. The material flow is recorded. The status display indicates that the calibration is running.
When the belt is empty, terminate the calibration using the command "Stop span
calibration with material batch" (68).
3. Enter the complete quantity of conveyed material before or after the calibration in DR3 in
the parameter "Calibration quantity (span calibration with material batch)".
Step 3
1. Calculate the scale characteristic using the command "Calculate span calibration point
after material batch" (69). The result is displayed in DR4.
2. Import the working point into DR3 using the command "Apply span calibration digits" (89).
The characteristic curve has thus been determined. The scale can calculate the weight
values for the complete load range.
