4. Judge if the error is within allowable range:
Note: You can calculate the horizontal collimation error by formula (Fl - F2 ±
180°) / 2 .
o
If the error is less than 8'', press F4 NO to exit.
o
If the error is greater than 8'' but less than 30'', press F3 YES to view
calibration data:
o
If the error is greater than 30'', press F4 NO to exit and do reticle adjustment:
i. Rotate the instrument at telescope right, and turn the horizontal
tang
ent screw until F2′ = F2 + C.
ii. Loosen the shield of the reticle of the telescope:
iii. Do the following to adjust the screws of reticle until the vertical hairs of
telescope’s reticle coincides with the cross-hairs of collimator or
target:
1. Loosen the screw on the moving direction of reticle.
Anticlockwise turning is for loosening, and clockwise turning is
for tightening.
2. Tighten another screw by the same mount.
iv. Repeat the whole adjustment process of the horizontal collimation
error until the error is less than 30''.
