3.5.5 Parameters and Tolerance Limits
To select the parameters that are to be evaluated
in the "Result" view and in the record:
1. Open the "Parameters" menu by pressing
the key.
2. Press the 1 key to display the parameters
in accordance with "ISO / ASME / JIS" or in
accordance with "MOTIF".
3. Select the parameters to be evaluated in
sequence by pressing the key (e. g. "Rmax"
with key 0) and activating the "Calculate"
check box.

4. To enter tolerance limits for the selected pa-
rameter:
Use the • 8 key to select the upper toler-
ance limit "
TOL" and enter the de-
sired value.
Use the • 9 key to select the lower toler-
ance limit "
TOL" and enter the de-
sired value.
5. Activate the
button by pressing the
key.
6. The selected parameters are displayed with
the tolerance limits in the "Parameters"
menu.
If the value "0.00" appears for "
TOL" or
" TOL", this tolerance limit has not been
defined.
When the value "0.00" is set for "
TOL"
and "
TOL", no tolerance monitoring oc-
curs for these parameters.
17 Or activate the "All" check box to evaluate all parameters
in accordance with "ISO / ASME / JIS" or "MOTIF".

Setting the intersection lines
for zone widths
With the three-zone meas urement, 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).
