8. Run the sensor and check that 3Ddata acquisition is satisfactory.
If 3Ddata acquisition is not satisfactory, adjust the exposure values manually. Switch to Video mode to use
video to help tune the exposure; see Exposure on page 83 for details.
When the sensor is set to Video mode, you can use a special "line" focus pattern to aid in focusing the
sensor. A focused sensor produces more accurate scans, which in turn results in more reliable
measurements.
To use the focus pattern:
1. Place a representative target in view of the sensor.
The target surface should be similar to the material that will normally be measured.
2. Go to the Scan page and choose Video mode.
3. Expand the Sensor panel by clicking on the panel header or the button.
4. Click the Exposure tab.
5. In Pattern Sequence, choose Focus Pattern.
A vertical line pattern is projected onto the surface (see next).
6. Move the sensor up and down until the dark lines are as sharp as possible.
