Repeat the above procedure for the other axis of the X-Y translation stage 90 degrees to the first one.

After centering, adjust the theodolite height as indicated below.

2.4 Adjust Height:

The height adjustment of the theodolite is accomplished with the precision lift (refer to Figure 18). This device can lower or raise the theodolite to the desired height by rotating the large rim located at the center of the upper body of the device. Ensure torque tube does not rotate when adjusting precision lift.

After the leveling and centering is accomplished, the theodolite must be adjusted to be in line with the scribe line of the alignment stick.

With the stick located at rib #10, first adjust the elevation angle of the theodolite to exact- ly 90 degrees 00 minutes and 00 seconds. Then, while the theodolite is set to this angle, focus to the scribe line and make any up or down adjustment with the lift. Record this as H1 (90 degrees).

Relocate the stick to rib #2. Focus and adjust the elevation to align to stick scribe line, record as H2.
