If the span adjust value is within the accuracy requirements of the weighing system, the material test was successful and normal operation can be resumed. If the span adjust value is not acceptable, repeat the material test to verify repeatability. If the result of the second material test differs considerably, consult Milltronics or its agent. If the span adjust values are significant and repeatable, perform a manual span adjust: refer to Maneuvering, page 18 for parameter selection and value change PROGRAM mode, P019 if % span adjust is negative, be sure to enter as negative value enter % span adjust, e.g. 0.05 jumps to P017 adjusted test load, e.g.
97.95 Verify the results of the span adjust by material test or return to normal operation Design Changes Where parameters have been changed with a resultant impact on the calibration or do not take effect until a recalibration is done, the parameter warning icon is displayed. In order to clear the icon, perform a zero and span recalibration after the reprogramming session is complete. If significant changes have been made, an initial zero (P377) and/or initial span (P388) may be required. Recalibration Recalibration In order to maintain the accuracy of the weighing system, periodic zero and span recalibrations are 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. 7ML19985DJ01 Milltronics BW100 - INSTRUCTION MANUAL Page 31
