Editing a Control
Introduction
The assigned mean, standard deviation (SD), constituent code and control ID of a
previously defined control can be edited. In addition, individual chemistries can be
added or deleted.
Editing Precautions
When editing control information, the following should be considered:
• Changing the mean and/or SD may affect subsequent QC statistical data.
• Changing previously defined mean and/or SD to zero will set the mean to zero and
the SD to 99999.
• Subsequent data points will be compared to the new mean and SD.
