Reviewing Calibration and Verification History
If you need to review the results summary of past calibrations, follow these steps:
1. Press the Menu button and select the Maintenance tab.
2. Press the Calibrate button.
3. Press the Cal/Ver History button.
•Press the Print History button to output the calibration history to the printer.
•Press the Export History button to output the calibration history to the USB port or the serial port in
text (.csv) format.
If you want to review specific measurements from calibration or verification, you can display the data history as
you normally would. The Mode column lists TC Cal and IC Cal for calibration results, TC Ver and IC Ver for
verification results, Sys Suit for system suitability results, and Linearity for Linearity results. These results also
are included when you export the data history.
The Analyzer’s Cal/Ver History is divided by protocol type, and a finite number of result summaries for each
type will be stored (see Table 12). Once the maximum number of stored result summaries is reached for a
particular protocol, the oldest result summary is overwritten by the newest result summary of the protocol type.
For calibrations, result summaries are stored in Cal/Ver History memory only if the calibration was applied.
