Quantitative Data

For quantitative characteristics, you can define additional specific quantitative data, depending on the control indicators you have set. You call this function using the Quant. data pushbutton on the general data screen for the master inspection characteristic.

  • For example, when you set the control indicators, if you specified that a lower and an upper specification limit were to be inspected, the system displays a Quantitative Data dialog box, in which you can enter data for these specification limits.

  • If, however, you defined that only the upper or lower specification limit is to be inspected, the system only displays the fields that correspond to the limit you selected.

  • If you use a tolerance key, the system copies the values from this tolerance key into the master inspection characteristic. You can, however, overwrite these values.

Note Note

A tolerance key groups industry-standard tolerance specifications, or those used in a particular sector (for example for fit) for a quantitative characteristic. A unit of measurement, target value, the accuracy and upper and lower specification limit are defined for the tolerance key.

Your system administration can define nominal values for the tolerance keys in Customizing These nominal values are based on tables in the DIN standards. If nominal values were defined for a tolerance key, the specification limits can vary on the basis of these nominal values.

You call this function using the menu path Start of the navigation path Goto Next navigation step Tolerance keys… End of the navigation path on the general data screen for the master inspection characteristic. If you check the data after entry, the system also displays the values for the unit of measurement and target value that were defined for this key and determines whether the specification limits are relative values for the target value. This only occurs if you have set the relevant indicator in Customizing.

If you delete a tolerance key, the values that were defined by the tolerance key in the inspection characteristic are not deleted. They remain as characteristic specifications.

End of the note.
