Section 8 Calibration
This instrument is calibrated at the factory. No user calibration is
necessary.
8.1 Standard calibration adjust
Use the standard calibration adjust (SCA) option when a calibration
must be adjusted to meet regulatory requirements. The factory
calibration is adjusted slightly with the standard calibration adjust
(SCA) option so that the instrument shows the expected value of the
standard solution. The adjusted calibration is then used for all test
results. This adjustment can increase the test accuracy when there are
slight variations in the reagents or instruments.
Note: For instruments with factory-calibrated ranges or methods, the standard
calibration adjust (SCA) feature is disabled when a user-entered calibration is
entered into the instrument. To set SCA back to on, set the instrument to the
factory default calibration. Refer to
on page 20.
