LEVEL TRAVEL AND LIFT INSPECTION
Line of sight shall not deviate in elevation from a horizontal target line by more than + 1.0 mil (total
excursion of 2 mils) when head is rotated through at least 2 full revolutions of travel.
Displacement of the horizontal line of sight, due to reversing direction of head rotation, shall not exceed
0.5 mil while observing reticle.
Set azimuth ring (1) to "0" coincidence on azimuth testing fixture (2).
