Note
The moisture meter is ignored during calibration. If inclinometer is used, then calibration is
adjusted based on in
cline 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 o
btain an accurate and successful calibration, ensure that the required criteria are met.
Refer to
Calibration Criteria (Page 199).
