continue to Span
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:
In order to obtain an accurate and successful calibration, ensure that the required
criteria are met. Refer to Calibration Criteria on page 139.
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.
