This completes installing the measuring head.

3.5. Preliminary Approaching and Selecting Scan Area

1. Watch from aside and rotate the approach knob 1 (Fig. 3-14) counterclockwise to
approach the sample to the probe to distance of ∼0.5 mm.
1 – approach knob; 2 – fine focusing screw of the objective
2. Switch on the illuminator of the videomicroscope, the CCD-camera, and the monitor
of the optical viewing system
3. Turn the fine focusing screw 2 (Fig. 3-14) to focus the objective on the sample
surface. Watch quality of the focus with the image on the monitor of the optical
viewing system. With proper focusing, the monitor displays a contrast image of the
sample surface.
4. To select an area for investigation, rotate the microscrews of the positioning device to
move the scanner with the sample to a position where the desired area is in the
viewing field of the objective. Monitor the surface by inspecting image on the monitor
of the optical viewing system.
This completes preliminary approaching and selecting the scan area.
