| Warning Limits

Use this dropdown list to select the
Warning limits type:
- None. If selected, the analysis will not generate any warning limits on the
X chart.
- Use defined UWL and LWL
- If
Use defined UWL and LWL option is selected, the analysis will look for variables named
*_UWL and
*_LWL for each characteristic (where '*' is the name of the characteristic) and use the values in the respective variables as the
Upper warning limit and
Lower warning limit values.
- Each time the value in the
*_UWL or
*_LWL variable changes moving downward in the column, the system will create a new set on the
X chart.
- If a value in the
*_UWL or
*_LWL variable is blank, the system will use the previous valid value found in the respective column.
- If no valid values are found in the
*_UWL variable, the
Calculated UWL will be used as the
Variance chart UWL value if the
Calculate if defined limits are blank checkbox. If this option is not selected, the chart will not have a UWL.
- If no valid values are found in the
*_LWL variable, the
Calculated LWL will be used as the
Variance chart LWL value if the
Calculate if defined limits are blank checkbox is selected. If it is not selected, the chart will not have a
LWL.
