Unloading the Sample
When a scan routine is complete, the stylus automatically lifts off the surface. To remove the sample,
from the fixture, click the
Unload Sample button to make the system move the sample-
positioning stage forward. You can now lift your sample off the fixture.
TOWERING UP AND DOWN
You must slowly lower the tower assembly to bring the feature that you want to measure into focus in
the Live Video Display. To do this, click the
Tower Down button on the toolbar above the Live
Video Display.
To raise the tower assembly, click the Tower Up button
.
To bring the tower all the way up to its home position, click the Tower Home button
.
NOTE –
The DektakXT profiler automatically towers down to bring the stylus into contact
with the sample whenever you start a single-scan measurement, 3D map scan, or automation
program.
ADJUSTING THE ILLUMINATION
After lowering the tower to focus the camera on your sample, you must adjust the illumination level
of the video image displayed on the monitor. To do this, move the slider on the Intensity Bar at the
bottom of the right pane of the Live Video Display (see
Figure 3-7 ). Move it to the right to increase
the illumination and to the left to decrease it. The feature that you want to scan should be clearly
illuminated.
NOTE –
When you save a Vision recipe, the illumination level is automatically included
along with the other measurement settings.
