The moisture meter is ignored during calibration. If inclinometer is used, then 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.
Note
To obtain an accurate and successful calibration, ensure that the required criteria are met.
Refer to Calibration Criteria (Page 199).
With the conveyor stopped and locked out, apply the test weight or chain to the scale as
instructed in the associate manuals; then start the conveyor.
