section B.3).
2)9 : If desired, exchange both mini sensors with fiber heads (refer to
section B.3) or for single point measurements exchange the mini sensor
of the reference fiber with a reference head (refer to section 5.6 and
section B.1) and the other mini sensor with a fiber head.
2. Make sure that the key switch on the controller is in position O.
3. Fix the mini sensor as appropriate to the flexible arm OFV-039 (refer to
section B.4) or to the OFV-036. This ensures a secure position and makes
it easier to focus on the object.
4. Position the mini sensor or fiber head according to the information on opti-
mal stand-off distances in section 4.2.4.
5. Align the mini sensor or fiber head such that the laser beam points along
the velocity vector to be measured, i.e. in general perpendicular to the
surface of the object.

by 10cm as it may be that the mini sensor or fiber head has been posi-
tioned at an unsuitable distance (refer to section 4.2.4).
