This indicates that the mechanical system is errant. Use P388, initial span, judiciously and
only after a thorough mechanical investigation.
Find and rectify the cause of the increased or decreased deviation. Then re-try a span
recalibration.
If this deviation is still unacceptable, set P388 to 1 to invoke an initial span calibration.
Further deviation limits are now based on this new initial span.
Press
This is the end of span calibration. Remove the test weight and return to RUN.
Note:
To obtain an accurate and successful calibration, ensure that no material is
flowing through flowmeter and the test weight is applied
