7-12. Performing a Calibration Check
A calibration check is similar to the calibration, with the primary difference being that no
changes are made to the stored constants, and the internal check standards are used as the
reference points. A calibration check produces a report similar to the normal calibration
report, and shows any proposed changes.
This procedure can be performed from an external computer, and can be set to run
automatically, with no assistance (there is no need to enable the CALIBRATION switch,
since no constants are changed).
You can use the calibration check at any time to confirm the integrity of the calibrator
without connecting external standards. The calibration check is also useful for collecting
a performance history.
Before you begin this procedure, make sure the calibrator is powered on and has
completed the appropriate warm-up period. Then follow this procedure to check the
calibration.
