Rt
(PosiTector RTR-3D probes only)
Rt Total profile height: the distance between the highest peak and the deepest valley
within the evaluation length.
Rz
(PosiTector RTR-3D probes only)
Rz Average maximum height of the profile: arithmetic average of the successive values
of the maximum peak to deepest valley within each sampling interval calculated over
the evaluation length. The length of the sampling interval is equal to the cutoff length
and the number of sampling intervals is the number of whole cutoff lengths that can fit
within the evaluation length.
Rq
(PosiTector RTR-3D probes only)
Rq RMS roughness: root mean square average of the profile heights within the
evaluation length measured from the mean line.
Rp
(PosiTector RTR-3D probes only)
Rp Maximum profile peak height: the distance between the highest point of the profile
and the mean line within the evaluation length.
3D Parameters
(PosiTector RTR-3D probes only)
3D parameters are calculated across the image area. When calculating 3D parameters,
an evaluation area is determined by removing an area around the outside edge of the
image area equal to the width of the discard length.
The 3D Parameter Menu allows the operator to select 3D analysis parameters to be
displayed by the gage (a maximum of 6 parameters can be selected from the 2D and
3D Parameter lists).
