4.4.2 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 S
ECTION
3.5
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 S
ECTION
4.1,
S
ECTION
4.2, S
ECTION
4.3, and in your software manual.
If your system does not perform as described above, read through the
information on troubleshooting provided in C
HAPTER
6 and contact your local
Polytec representative.
< 1.5 m Cover the retro-reflective film in any
case. With optically poorly reflective
surfaces treat the object with white
paper and carry out the distance
measurement.
≥ 1.5 m Treat the object with retro-reflective film
and carry out the distance measurement
on the retro-reflective film.
