Summarized Results Recording
Use
When you record summarized statistics, you can process the following types of results:
Features
Number of Defects
For purely attributive results recording based on the number of defects, you enter the number of inspected single units for an inspection characteristic or a partial sample in the Inspected field. For each inspection characteristic in the task list, you can define how much the inspected sample size in the Inspected field can deviate from the predefined sample size in the Inspect field. When you close the inspection characteristic or partial sample, the system checks whether the conditions for adhering to the sample size have been met.
The confirmation of the number of defects is defined by a control indicator in the inspection characteristic in the task list.
To confirm the number of defects observed in the sample, enter the number of defects in the No. of defects field. When you confirm the number of defects for the first time, the number of inspected units is automatically recorded (= target sample size). You can confirm more than one defect for an inspected unit.
Number of Nonconforming Units
In the Inspected field, you enter data as described in the above section, "Number of Defects".
The confirmation of the number of nonconforming units is defined by a control indicator in the inspection characteristic in the task list.
To confirm the number of nonconforming units, enter the number of defective sample units in the Defective field. This number cannot be greater than the number of inspected units specified in the Inspected field. When you confirm the number of nonconforming units for the first time, the number of inspected units is automatically recorded (= target sample size).
Coded Characteristic Attributes for the Inspection Characteristic
You can confirm coded characteristic attributes for an inspection characteristic, if you have assigned a selected set to the characteristic in the inspection plan.
For more information, see
Assigning Code Groups or Selected Sets.
Quantitative Confirmation
For quantitative inspection characteristics with a single-sided or double-sided tolerance range and for which a summarized quantitative confirmation is defined, you can make the following entries:
Field Name |
Possible Entry |
Comment |
Inspected |
Number of inspected singles units |
|
No. above or No. below |
The number of inspected single units above or below the tolerance range |
After you enter the values and choose Enter, the system determines the number of nonconforming units from the number of inspected single units outside the tolerance range. The number of nonconforming units is displayed in the Nonconforming field. |
s |
Standard deviation for valid measured values |
|
x-bar |
Mean value for valid measured values |
For quantitative inspection characteristics without tolerance limits, enter the number of nonconforming units in the Nonconforming field. The fields No. above and No. below are not displayed.
If no quantitative confirmation is defined for a quantitative inspection characteristic with a single-sided or double-sided tolerance range, enter only the number of single units above and/or below the tolerance range.
