For example, the new test load value is displayed.
Verify the results of the span adjust by material test or return to normal operation.
Where parameters have been changed with a resultant impact on the calibration, they do not
take effect until a recalibration is done.
If significant changes have been made, an initial zero (P377) and/or initial span (P388) may be
required (See, under P377 (Page 171) or P388 (Page 171)).
To maintain the accuracy of the weighing system, periodic zero and span recalibration is
required. Recalibration requirements are highly dependent upon the severity of the application.
Perform frequent checks initially, then as time and experience dictate, the frequency of these
checks may be reduced. Record deviations for reference.
The displayed deviations are referenced to the previous zero or span calibration. Deviations are
continuously tallied for successive zero and span calibrations, and when exceed their limit
(+12.5 and -12.5 from the initial zero or span), indicate an error message that the deviation or
calibration is out of range.
Note
To obtain an accurate and successful calibration,
ensure that the required criteria are met.
