Note:
calibration is adjusted based on incline angle.
Span Calibration
When performing a Span Calibration where the test reference is ECal (P002 = 3), the
supplied test weight or test chain must not be applied, and the conveyor must be run
empty.
To obtain an accurate and successful calibration, ensure that the required
