If the profile was evaluated with profile inversion,
the profile type is displayed with a minus sign
(e. g. "R–" or "P–").
To change the vertical scale VER for the profile
diagram and the material ratio curve:
21
Activate the •
+
button by pressing the
key to increase the vertical scale.
Activate the •
–
button by pressing the
key to decrease the vertical scale.
To display the material ratio curve MRC:
1. Activate the "PRF" button by pressing the
key.
Use the "MRC" button to display the profile
diagram again.
Meas uring results of the parameters
The parameters switched on in the "Parameters"
menu are displayed below the profile diagram.
If the tolerance is exceeded for one of
the selected parameters, this parameter
is displayed first and a plus or minus sign
appears between the meas uring result
and the unit.
To display the meas uring results for the other se­
lected parameters:
1. Using the arrow keys and the slide in
the scrollbar can be moved down or up.
If "*****" is displayed instead of a meas uring re­
sult the result cannot be calculated because the
conditions for calculating the result for this pa­
rameter were not fulfilled (see Section 7).
21 The vertical scale set in the "Record" menu is not modi­
fied.

5. After the meas urement has been carried
out, the pick­up travels back to its starting
position and the "Result" view is displayed
(see Section 5.2.1).
Ensure that the upper meas uring range
limit is not exceeded during return travel
as this can damage the pick­up!
Aborting the meas urement
Meas urement can be aborted at any time by
pressing
START . The traverse is stopped imme­
diately. When starting a new meas urement the
pick­up travels back to its starting position.
Invalid meas urement
Pick­up deflection is monitored during the meas­
urement. If the meas uring range is exceeded, the
traverse is stopped immediately. An error mes­
sage is displayed. When starting a new meas­
urement the pick­up travels back to its starting
position.
5.2 Evaluation
"Result" View 5.2.1
After an error­free meas urement is carried out,
the "Result" view is displayed with the profile
that corresponds with the standard and the se­
lected parameters.
The meas urement can be evaluated immediately
if the evaluation conditions (see Section 3.5.3)
and some of the basic settings (see Section 3.5.2)
are set correctly.
Profile diagram and material ratio curve
Depending on the standard selected, the profile
diagram of the R­profile (ISO / ASME / JIS) or
the P­profile (MOTIF) is displayed.
