3. Make the cut-off/length and parameter selections required
4. Position the display-traverse unit and pick-up so that
the stylus contacts the surface and the pick-up is
approximately parallel to the surface. Make sure that the
length of surface is sufficient for measurement,
remembering that the traverse motion is inwards towards
the display-traverse unit.
5. Press the Measure key. When the traverse is completed,
the results are displayed and the pick-up returns to its
extreme outward position.
6. If an error message is displayed, identify the cause,
correct it and repeat the measurement.
On other surfaces
On a cylindrical surface:fit the optional roll and bore plate
On a vertical surface:If necessary, hold the display-traverse unit by
hand on the surface, making sure that it does not move during the
measurement
In a small deep bore:Fit the optional extension rod between
pick- up and holder.
Cut off
A few trial measurements made on different surfaces will soon
demonstrate that on some, the results obtained are very dependent
upon the cut-off selected. This shows that it is important to choose
the cut-off to suit the surface. In general, fine surfaces require
short cut-offs and rough surfaces a longer one. The table on the
following page gives some guidance on suitable cut-offs.
