24.3 Inclination of Reticle
·
Inspection
1. Aim at object A through the telescope and lock the horizontal and vertical clamp screws.
2. Move object A to the edge of the field of view with the vertical tangent screw (point A′)
3. No adjustment is necessary if object A moves along the vertical line of the reticle and point A′ still in the vertical
line.
As illustrated
，Ａ
′offsets from the center and the cross hair tilts, then need to adjust the reticle.
·
Adjustment
1. First remove the eyepiece cover to expose the four reticle adjusting screws.
2. Loosen the four reticle adjusting screws uniformly with an adjusting pin. Rotate the reticle around the
collimation axis and align the vertical line of the reticle with point
Ａ
′.
3.Tighten the reticle adjusting screws uniformly
，
Repeat the inspection and adjustment to see if the adjustment is
correct.
4. Replace the eyepiece cover.
24.4 Perpendicularity of Collimation Line to Horizontal Axis (2c)
Inspection
1. Set object A at a far distance the same height as the instrument, then level and center the instrument and turn on
the power (horizontal angle L=10°13′10″).
2.
Aim at object A in left position and read the horizontal angle value (horizontal angle R= 190°13′40″).
3
.
Loosen the vertical and horizontal clamp screws and rotate the telescope. Aim at object A in right position and
read the horizontal angle value.
