Wrench Quality Rundown Stage Parameters
The parameters shown in the tables are available if one of the STwrench strategies are used. There are several combinations of strategies. Some of the parameters are only available for certain strategies and may not be visible in other strategies.
Parameter rules are automatically checked. If a violation occurs, the error indicator 
is displayed beside the incorrect parameters. Select the error indicator to display more information about the error.
Switching between strategies can result in the error indicator being shown. This indicates that the chosen combination is invalid, and needs to be corrected.
