Select the required characteristics
With the cursor keys select a class.
Display the histogram for the chosen characteristic.
The width of the each bar depends on the number of
classes processed and is adapted automatically. The
dotted lines indicate the tolerance limits (the tolerance
limits are not shown if the measuring values lie outside
the specified standard deviation - sigma range).
Nominal value :
in mm or inch.
Upp. all
:
Upper allowance.
Low. all
:
Lower allowance.
Width
:
Class width – computed on the basis of the tolerance window divided by the number of
classes.
Class
:
Number of classes.
< low. tol
:
Number of measuring values below the lower tolerance limit.
> upp. tol
:
Number of measuring values above the upper tolerance limit.
Mean value
:
Mean of all the measured values of a characteristic.
Up. relia.
:
Upper reliability limit of the mean value. Shows the limits within which the mean value of the
population lies. The reliability is 95%.
