The Category Limits Dialog is used by the Category Limits Section to add, remove, and edit the composition limits which will be used in a graphical or combinatorial mixture design.
The dialog is activated by clicking the left mouse button on the section's table control or by clicking the right mouse button on the table control and selecting the 'Edit Data' command from the field's commands menu.
The Category Limits Dialog enables you to edit the compositions for each component category. (The component categories must be entered first in the Design Categories Section.)
|
1
|
Category Limits Table: lists the composition limits and increment for each component category. Note that one and only one component category must have an increment of 'q.s.', i.e., quantum sufficit. |
|
2
|
Minimums Total Control: displays the total of all entered minima. This total must be less than or equal to 100 wt%. |
|
3
|
Maximums Total Control: displays the total of all entered maxima. This total must be greater than or equal to 100 wt%. |
|
4
|
Edit Button: activates the Edit Category Limit Dialog which enables you to add or modifiy the limits, increment, reference, and comment of the currently selected component category. |
|
5
|
Commands Button: pressing the dialog's Commands button or clicking the right mouse button on the table control displays the commands menu. This menu provides standard commands for copying, pasting, and clearing category limit values. See the documentation on Common Menu Commands for details. |
Pressing the Edit button activates the Category Limit Dialog. This dialog enables you to enter limits, an increment, and supporting information.
|
1
|
Category Control: displays the currently selected component category whose limits are being edited. |
|
2
|
Description Control: displays the description of the current component category. This value is retrieved from the values entered in the Design Categories Section. |
|
3
|
Minimum Limit Control: enables you to enter the minimum concentration limit for the current component category. |
|
4
|
Maximum Limit Control: enables you to enter the maximum concentration limit for the current component category. |
|
5
|
Increment Control: enables you to enter either the incremental concentration the mixture design will use to generate compositions or the term 'quantum sufficit'. See below for additional documentation. |
|
6
|
Reference Control: the Reference control enables you to enter the identifier of the reference from which you obtained category limits. You can type in a value or use the dropdown list to select a recently entered value. Entering a reference is optional but highly recommended. |
|
7
|
List Button: pressing the List button displays the Reference Selection dialog. This dialog enables you to select the identifier of any reference in the current document. (See the All Entities dialog documentation for more details on selecting references.) |
|
8
|
Comments Control: the Comments control enables you to enter general information to describe the entered limits. Very often comments document the date of entry, the name of the person who entered the value, assumptions about the entered value (e.g., use level restrictied to less than 1 wt%). |
|
9
|
Date, Phrase, Set Buttons: these buttons provide standard operations to help you enter comments. Pressing the Date button inserts the current date and time into the comment control. Pressing the Phrase button inserts the stored 'common phrase' into the comment control. Pressing the Set button enables you to change the 'common phrase'. (See documentation on the Set Phrase dialog for details. |
|

|
Show Ref Button: pressing the Show Ref button will display the document associated with cited reference. The location of this document is stored in the reference's Document Location Section. |
Selecting or entering quantum sufficit as the increment for a category limit means that the mixture design will assign composition values to all the other categories first, and then assign the residual value, i.e., the value that brings the total concentration to 100 wt%, this is category. One, and only one, component category must have quantum sufficit selected as its increment.
