Switching the profile inversion on or off
Usually a profile is evaluated in the same way
that it is measured, i.e. profile peaks are also
handled as such.
However, for replica measurements profile in­
version should be switched on. This causes the
measured profile to be mirrored on the diagram
mean line so that the evaluation is based on a
profile in the correct position.
If a profile is evaluated with profile inversion, the
profile type is displayed in the "Result" view with
a minus sign (e.g. "P–").
For MOTIF parameters, the measuring
i
value is affected by profile inversion.
Setting the operators
for MOTIF evaluation
When calculating the measuring results for the
MOTIF parameters, operators are used which
define the maximum length (in mm or in) of the
roughness motifs (operator A) or the waviness
motifs (operator B).
ISO 12085 states that operators A and B are se­
lected according to the expected length of the
motifs. Unless otherwise specified, the default
values are A = 0.5 mm and B = 2.5 mm.

Setting the intersection lines
for zone widths
With the three­zone measurement, zone widths
CR, CF and CL are calculated. For each of these
parameters, two intersection lines are specified
(in %), which determine the position of the re­
spective zone in the material ratio curve (48).
