beam shutter on the sensor head is in position OFF.
2. Fix the sensor head as appropriate with the M6 or 1/4" threaded mounting
holes onto a universal tripod with a fluid head. This ensures secure sup-
port and makes it easier to focus on the object.
3. Position the sensor head according to the information on optimal stand-off
distances in section 4.2.4.
4. Align the sensor 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.

9. If the signal level is low or highly fluctuating, change the stand-off distance
by 10cm as it may be that the sensor head has been positioned at an
unsuitable distance (refer to section 4.2.4).
