8. Azimuth Dial
a. Performance Check
(1) Adjust azimuth tangent knob to superimpose telescopes azimuth reticule line to
collimator projector azimuth reticule line.
(2) Adjust altitude tangent knob to superimpose telescopes altitude reticule line to
collimator projector altitude reticule line.
(3) Adjust circle setting knob to 0.
(4) Adjust optical micrometer knob to 0.
NOTE
Check azimuth and vertical alignment of telescope and
collimator projector to insure they are still aligned. If not,
repeat (1) through (4) above.
(5) Unlock azimuth test fixture and rotate ccw to 800 mils. Lock test fixture.
(6) Realign telescope reticule to collimator projector reticule lines.
(7) Sight through microscope and observe reading. Reading will be 800, 0.05 mils.
(8) Repeat (5) through (7) above at 800 mil intervals throughout 6400 mils of
azimuth test fixture. Reading will be 0.05 mils of TI setting.
b. Adjustments. No adjustments can be made.
9. Final Procedure
a. Deenergize and disconnect all equipment.
