5. Sight the angle of the CRU face and read off the template This gives the angle as seen from
the underside. You may wish to attach a rod through the mounting bracket of the CRU so that
the direction of the CRU is more readily readable. Mark the angle with a non-permanent
marker.
6. Translate the reading onto the Survey Form. To do this place the template with the underside
on a piece of paper (i.e. all text appears backwards.) The view now observed is the same as
that from above the CRU. Mark the survey form with the correct panning angle and hinge
orientation. Note: The sketches on the survey form show the orientation traditionally from an
overhead view.
