          A warning message displays that updating the QC database will take some time.

       4. Click OK to proceed.

4. To select an analysis code:

   Note: The analysis code allows you to input the Target Initial Measurement, Allowable Variance, and Target Final Measurement when utilizing reference materials during pre-analysis.

   1. Select the reference standard and click Setup » Analysis Code.

      The Standard Analysis Codes screen displays.

   2. Select the analysis code from the Available Analysis Codes list.

   3. Click the Add Code icon to add the analysis code to the Selected Analysis Code list.

   4. Click the Edit Client Package icon.

      The Edit Standard Analysis Code screen displays.

   5. Enter values for the following fields as required:
