Daily control averages (upper chart)

·   The daily control averages are plotted on the upper chart.

·   An omitted daily control average is colored in red.

·   Guidelines extend from the vertical axis at concentrations corresponding to the control mean (X), the ±2 SD limits, and the ±3 SD limits.  

·   The ±2 SD and ±3 SD limits    are calculated from the QC Cumulative SD entry at the Control Data Setup window.

·   The control mean value  is obtained from the QC Cumulative Average entry at the Control Data Setup window.

·   A maximum of 63 data points from the daily QC are displayed in cumulative QC graphs.

Daily fluctuation ranges (lower chart)

·   The daily fluctuation ranges are plotted on the lower chart.

·   Each data point represents the difference between the daily QC and the established cumulative QC mean.

·   Guidelines extend from the vertical axis at concentrations corresponding the +2 and +3 SD limits.  

·   The +2 and +3 SD limits  are calculated from the QC Cumulative SD entry at the Control Data Setup window.
