Daily control charts

About the Daily Control charts:

·   Each control result is plotted on a Levey-Jennings type chart.

·   A maximum of 200 control sample results are managed. If additional control samples are run, the oldest control sample results are replaced with the newer results. Omitted control results are colored red.

·   Select the Test Name button  to view the detailed information.

·   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 Daily QC SD entry at the Control Data Setup window.

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