 Values for the Master Inspection Characteristic

You can display or change values for master inspection characteristics (for example, inspection specifications, such as, decimal places, specification limits, unit of measurement, or data for the characteristic ID and data origin) in the following ways:

  • You select the required master inspection characteristic and choose Detail under the table.

  • You choose Detail in the line of the table that contains the required master inspection characteristic.

Changing Values

You can only change the inspection specifications for a master inspection characteristic, if

  • It is not assigned to a class characteristic in the material specification

  • The reference to a master inspection characteristic has been cancelled. This means that the master inspection characteristic has been unlocked.

If you change inspection specifications, they are stored directly in the material specification. The advantage of this is that you can define material-specific tolerance limits without having to create several master inspection characteristics.

You define an additional characteristic description in the field Characteristic ID or change the existing characteristic description in the master inspection characteristic. This description is used to identify a characteristic during the electronic exchange of characteristic values.

You specify in the field Data origin from which data source (for example, handheld application, quality certificate) the results data should be copied.

Entering a sampling procedure

If the control indicator Sampling procedure is set in the inspection characteristic, you can enter the following sampling procedures:

  • Sampling procedure for a lot-based inspection

This sampling procedure is used for an inspection with a task list and material specification, if a lot-based inspection is specified in the task list and the master inspection characteristic is only used in the material specification. If the master inspection characteristic is also used in the task list, the sampling procedure specified in this task list is used. If no sampling procedure has been defined in the material specification or task list, the sampling procedure defined in Customizing is used in the inspection.

  • Sampling procedure for an inspection point-based inspection

This sampling procedure is used for an inspection during production with a task list and material specification, if an inspection-point-based inspection is specified in the task list and the master inspection characteristic is only used in the material specification. If the master inspection characteristic is also used in the task list, the sampling procedure specified in this task list is used.
