Calibration Adjust (InCal models)
Calibration Adjust may be used to adjust the result of the internal calibration by ±100 divisions.
Note::::: Before making a calibration adjustment, perform an internal calibration. To verify whether an
adjustment is needed, place a test mass on the platform and note the difference (in divisions)
between the nominal mass value and the actual reading. Refer to Section 3.7.2 and use the
highest value from the Span Calibration Points column as the test mass. If the difference is within
±1 division, calibration adjustment is not required. If the difference exceeds ±1 division, calibration
adjustment is recommended. Following a calibration adjustment, repeat the internal calibration
and verification procedures.
