Inspection Point

Characteristics visible at the Inspection Point level are of the Inspection usage and Attribute or Variable type. They may be defined in the Process associated with the SOP or added directly in the SOP Designer. Characteristics defined in the Process cannot be unlinked, and they can be distinguished from Characteristics added directly in the SOP Designer by the following icons: (for Characteristics of the Variable and Attribute type) and (for Characteristics of the Variable type).

At the Inspection Point level:

The user cannotunlink the Characteristics defined in the Process associated with the SOP
The user canmanually link Characteristics of the Variable and Attribute type
The user canunlink Characteristics of the Variable and Attribute type which were manually added by the user (not defined in the Process)
The user canadd and remove Attributes to Characteristics of the Attribute type (both those added manually and those defined in the Process, unless the Inherited flag is selected, in which case the Attributes are inherited, are directly linked with the Process, and cannot be modified)
The user can edit Attributes, Attribute description, and conforming flag for Characteristics of the Attribute type (both those added manually and those defined in the Process, unless the Inherited flag is selected, in which case the attributes are inherited, are directly linked with the Process, and cannot be modified)
The user can edit Characteristic limits, target values, and UOM for Characteristics of the Variable type (both those added manually and those defined in the Process)

Characteristics of the Variable Type

Color codes for the font of Characteristics of the Variable type help the user make sure he or she stays within the limits defined in the Process. The color codes are applicable to the following fields: Upper Coherence Limits (UHL), Lower Coherence Limits (LHL), Upper Specification Limits (USL), Lower Specification Limits (LSL), Upper Control Limits (UCL), and Lower Control Limits (LCL).

Color	Description
Black	The value was not changed (Process value = SOP Value).
Green	The value was changed and is consistent with Process values.
Red	The value is not consistent with Process values.

The columns for the Characteristic of type Variable are by default populated with the values copied from the Characteristic properties, but some fields can be modified.

Column	Description
Characteristic	The unique ID of the Characteristic.
Revision	The revision of the Characteristic.
Type	The type of the Characteristic: Attribute, Variable.
Inherited	The flag indicating if the values of a given Characteristic are inherited from the Process. To modify, select or deselect the check box.
UHL	The Upper Coherence Limit: the most extreme (tolerant) limit that can be used to indicate a result as being extremely incorrect, not recordable, or requiring additional manual action to continue the measurement. To modify the value, click the field and provide the new limits.
USL	The Upper Specification Limit: the range threshold defining the highest possible value the Attribute being measured can have to fulfill the specification demands. This value is used to calculate the final test conformity. To modify the value, click the field and provide the new limits.
UCL	The Upper Control Limit: the range threshold defining the highest possible value the Attribute being measured can have to fulfill the demands of the current control. This value is meant to narrow the Upper Specification Limit and has only informative meaning. To modify the value, click the field and provide the new limits.
Target Value	The most satisfactory (expected) value of the Characteristic. To modify the value, click the field and provide the new limits.
LCL	The Lower Control Limit: the range threshold defining the lowest possible value the Attribute being measured can have to fulfill the demands of the current control. This value is meant to narrow the Lower Specification Limit and has only informative meaning. To modify the value, click the field and provide the new limits.
LSL	The Lower Specification Limit: the range threshold defining the lowest possible value the Attribute being measured can have to fulfill the specification demands. This value is used to calculate the final test conformity. To modify the value, click the field and provide the new limits.
LHL	The Lower Coherence Limit: the most extreme (tolerant) limit that can be used to indicate a result as being extremely incorrect, not recordable, or requiring additional manual action to continue the measurement. To modify the value, click the field and provide the new limits.
UOM	The unit of measure for the selected Characteristic. To modify the UOM, click the drop-down menu on the grid.
Ref UHL	The Upper Coherence Limit value defined in the original Process.
Ref USL	The Upper Specification Limit value defined in the original Process.
Ref UCL	The Upper Control Limit value defined in the original Process.
Ref Target Value	The target value defined in the original Process.
Ref LCL	The Lower Control Limit value defined in the original Process.
Ref LSL	The Lower Specification Limit value defined in the original Process.
Ref LHL	The Lower Coherence Limit value defined in the original Process.
Ref UOM	The UOM of the limits defined in the original Process.

Characteristics of the Attribute Type

Two grids exist for Characteristics of the Attribute type. The columns of the first grid are the same as in the case of Characteristics of the Variable type. However, the values of the limits are always displayed as null and cannot be edited, as these values do not apply to Characteristics of the Attribute type. To see and edit the details of Characteristics of the Attribute type, click

to expand the grid. To collapse it, click

Column	Description
Attribute	The name of the Attribute (e.g., the color) that identifies the feature of the sample being tested. To modify the name, click the field and provide a new name.
Conforming	A flag indicating if the attribute conforms to the accepted attributes. To modify, select, or deselect the check box.
Description	A description of the Attribute. To modify the Description, click the field and provide a new one.

These fields cannot be edited if the Inherited flag for a given Characteristic is selected. If the Attributes were added in the SOP and the user selects the Inherited flag, these Attributes will be removed. After deselecting the flag, the Attributes will be displayed again.

Actions

To add a new Characteristic of the Variable or Attribute type, click (Add) on top of the Inspection Point grid. The Characteristics pop-up window will be displayed where it is possible to choose an existing Characteristic or create a new one and add it to the SOP.

To remove a Characteristic which was manually added to the Inspection Point, select the Characteristic and click (Remove) on top of the Inspection Point grid.
To add a new Attribute to an existing Characteristic of the Attribute type, expand the given Characteristic grid and click (Add) on top of the Attribute grid. A new row will be added where it is possible to define the Attribute name, Conforming flag, and Description.

To remove an Attribute from a Characteristic of the Attribute type, select the Attribute and click (Remove).

Attributes cannot be added or deleted if the Inherited flag for a given Characteristic is selected.
