The accuracy of the Laser Measurement System can be no better than the mounting of the plane
mirror reflector. To maintain system accuracy, the plane mirror reflector must be mounted flat. When
performing dual axis measurements, the plane mirror reflectors must be mounted perpendicular to
the plane of measurement and at 9 0 ' to each other.
Operation Test
For an operational test, refer to the Plane Mirror Alignment procedures in Section 2 of the 5501 Laser
Transducer System Manual.
