3 First Steps
Switch on
5. Switch on the front-end by turning the key switch to position I.
The POWER L
ED
on the front of the front-end lights up. If all the
connecting cables are correctly installed, then the LASER L
ED
on the
scanning head lights up. Laser light may not be emitted yet as the beam
shutter is still closed.
6. Switch on all optional peripheral devices.
7. Switch on the PC.
NOTE!
After the PC has been switched on, at first all system components are initialized. This
initialization takes about 30 seconds. Not till then you can start the software.
8. Start the data acquisition as described in your software manual.
NOTE!
Before working with laser light, read the information on laser safety in
SECTION
1.2!
9. Open the beam shutter on the front of the scanning head.
The laser beam is now emitted from the scanning head.
WARNING!
Danger of injury caused by laser light! Do not look directly into the laser beam!
Do not use any reflective tools, watches etc. when you are working in the beam path of the
laser!
Wear suitable laser adjustment eyewear when you have to look at the target area of the laser
beam long and hard to set it up!
Test
10. Test the scanning head control (position and focus of the laser beam,
zoom and focus of the video camera) as described in your software
manual.
11. Put a matt, white test surface, such as a piece of paper, approximately
50cm away from the front of the scanning head in the beam path.
12. Focus the laser beam on the test surface.
The scanning head works correctly if the signal level display on the
scanning head lights up.
NOTE!
The instrument does not reach its optimal metrological properties until a warm-up period of
approx. 30 minutes. For measurement tasks with high angular stability requirements we
recommend a warm-up period of 120 minutes. This applies especially when you are working
with imported 3D geometries.
If this functional test was successful, you can now make measurements with
the system as described in
CHAPTER
4 and
CHAPTER
5 and your software
manual.
