◆ When calibration results are received on the display, they are saved as calibration
data and not received as sample results.
◆ Calibration results are not transmitted to a host computer, they are kept in the
calibration “Results Grid”.
◆ If a calibration cycle is rejected, it will not be displayed or stored. An error mes-
sage will be displayed on the screen indicating that the calibration sample was
rejected.
