Optics Adjustment (professional technician only)1. Use the tangent screw to adjust the horizontal angle to the right reading whichhas been eliminated C, R+C=190°13′40″-15″=190°13′25″2. Take off the cover of the reticle between the eyepiece and focusing screw.Adjust the left and right adjusting screws by loosening one and tightening theother. Move the reticle to sight object A exactly.3. Repeat inspection and adjustment until｜2C｜<20".4. Replace the cover of the reticle.Note: After adjustment, need to check the photoelectricity coaxiality.10.5 VERTICAL INDEX DIFFERENCE COMPENSATIONCheck1. Mount and level the instrument and make the telescope parallel with the lineconnecting the center of the instrument to any one of the screws. Lock thehorizontal clamp screw.2. After turning on the power, zero the vertical index. Lock the vertical clampscrew and the instrument should display the vertical angle value.3. Rotate the vertical clamp screw slowly in either direction about 10mm incircumference, and the error message “b” will appear. The vertical axis inclination
