1.5 “Clock" the Theodolite Assembly:

Refer to Figure 20. The theodolite support assembly must be 'clocked' to the brass rod holders such that two of the tribrach leveling screws run parallel with ribs 2 and 10 (see enlarged view in Figure 20). This can be accomplished by rotating the top flange of the torque tube which will rotate the entire theodolite assembly.

Calibration:

Note: Before adjustments, make sure that all the hardware connecting the torque tube to the reflector are fully tightened. Any loose hardware will cause improper theodolite align- ment.

2.1 Calibration Sequences:

1)Leveling (sect. 2.2)

2)Centering (sect. 2.3)

3)Adjust Height (sect. 2.4)

4)Repeat 1-3 as necessary (typical 4-5 times) to achieve calibration specifications.

5)Ready for reflector alignment.

2.2 Leveling:

After installation onto the torque tube, it is necessary to level the theodolite to the reflec- tor. This can be accomplished by adjusting two of the three leveling screws of the tri- brach.

With the stick at rib #2, focus and adjust the theodolite elevation to the scribe line and record this reading as R1.
