A.1.2 Functional Test
For an initial functional test with the geometry scan unit, proceed as follows:
1. Carry out a functional test with the system as described in
SECTION
3.6
and in the software manual.
2. Make a distance measurement ( Geometry Point ) as described in your
software manual.
3. Check the determined stand-off distance (distance between scanning
head and scan point), e.g. with a measuring tape.
If the functional test has been successful you can now make measurements
with the system and the geometry scan unit as described in
SECTION
4.1,
SECTION
4.2,
SECTION
4.3 and your software manual.
If your system does not perform as described above, read through the
information on fault diagnosis provided in
CHAPTER
6 and, if necessary,
contact your local Polytec representative.
