Updating the QC Cumulative window

  1. Review the daily control results.

If necessary, omit invalid control results you do not want included in the cumulative QC data. You must select Save after omitting control results.

  1. Select QC Cumulative Calculation.

  2. Read the displayed message box.

  3. Select Yes if the daily QC results are valid.

The results are included in the cumulative QC data.

  1. In the Control (C) list of the QC Cumulative Calculation dialog box, select the controls you want to update.

By default all controls are selected.

  1. Select OK.

As a data point for the current day, the system saves the daily mean and fluctuation range (R) for every test in each selected control in the QC cumulative window.

 caution

To avoid losing QC statistics, please observe the following:

·   Update the QC Cumulative window before more than 200 daily control samples are run.

·   The QC Daily Precision Control window can manage a maximum of 200 results for each control product (level). The system saves only the most current QC data when more than twenty controls are run in a day. (If an additional control sample is run, the oldest control sample is deleted to make room for the new one. Similarly, if you request multiple repetitions (up to 5) of a control when 200 results are already stored, the system aspirates the sample multiple times and saves the results as the last ones in the sequence, discarding the same number at the beginning of the sequence.)

·   To avoid losing control results, you must perform a QC cumulative save on the QC Daily Precision Control window at the end of each day, and perform a New Start when you turn on the system the next day.

·   Do not update the QC Cumulative window more than once each day.

·   If you return to the QC Daily Precision Control window after performing a "QC cumulative save," you must not perform another update.

·   You must not perform an update when no daily control data is available. If you do, the cumulative data point is deleted for today and you cannot save additional control data for the day.
