4. Based on +/- 6 SIGMA
Enter the number of classes (3-20)
Decide whether the tolerance limits or the sigma
values
are to be the criteria for sizes to be considered for the
histogram.
Based on allowances means that no sizes
are classified that are more than one class width
outside the tolerance limits.
Based on +/- 3 (6) SIGMA
means that no sizes are classified which are beyond
± 3 or ± 6 standard deviations.

The number of printed classes agrees with the number
entered in the „Histogram parameters“ menu. The
specified number of classes lies within the tolerance
limits and one extra class is added for sizes both above
the upper tolerance limit and below the lower tolerance
limit. Class limits are shown as dotted lines.
Next to the histogram, the probability net is also shown,
this illustrates the deviation from a standard
distribution.
Below, the histogram, a table of output which contains
the limits of each individual class, the number of parts
within each class and the percentage which represents
of the total number of workpieces.
