Figure 7-12. Detection

Configuration screen for

Coefficient of Variation

Standard Deviation Sensitivity, Mean Sensitivity

Shows the current sensitivity level for detecting changes in standard deviation

or mean. Users can choose from preset values of High, Medium, and Low.

Custom sensitivity levels can also be configured.

Coefficient of Variation Sensitivity

Shows the current sensitivity level for detecting changes in the coefficient of

variation. Users can choose from preset values of High, Medium, and Low.

Custom sensitivity levels can also be configured.

Figure 7-13 illustrates the differences in preset sensitivity limits of High,

Medium, and Low. The preset High sensitivity setting (e.g. 20%) will cause the

SPM diagnostic to be more sensitive to changes in the process profile. The

preset Low sensitivity setting (e.g. 80%) will cause the SPM diagnostic to be

less sensitive as a much greater change in the process profile is needed to

trip the alert.
