The mounting
4.6.2.3.1 Mounting bracket for dioptometer
bracket shall consist of a sleeve and mandrel joined by a
connecting arm. The geometric axis of the sleeve and mandrel
shall lay in the same vertical plane within .001 inch. The
geometric axes of the sleeve and mandrel shall also be horizontal
and parallel to each other with .001 inch. The geometric axis of
the sleeve shall be l.50 + .25 inch above the geometric axis of
the mandrel. The inside diameter of the sleeve shall be capable
of accepting the dioptometer, 7680631 (outside diameter 1.18
-.01 inch). The sleeve shall secure and maintain the dioptometer
in a horizontal position. The mandrel shall have a length of
1.000 + .250 inch and an outside diameter of .624 - .001 inch.
Install the dioptometer in the sleeve of the bracket. Rotate the
dioptometer until its vertical reticle line lays in the same
vertical plane that contains the geometric axes of the sleeve and
mandrel. Lock the dioptometer in this position.
4.6.2.3.2 Wall tarqet. A calibrated wall target shall be
utilized in measuring the elevation accuracy requirements of the
mount. The wall target shall contain a vertical and horizontal
crossline pattern together with limiting displacement marks
needed to determine line of sight deviations (azimuth shift)
during elevation travels. This wall target shall be calibrated
for a measured distance between 6.0 and 9.0 feet, as measured
from the mechanical rotational axis (elevation) of the mount.
