Leveling
When you level the instrument, you make the vertical axis of the instrument exactly
vertical. To level the instrument, use the plate level.
To level the instrument:
1. Loosen the upper plate clamp.
2. Rotate the alidade until the plate level is
parallel with any two of the leveling screws
(B and C).
3. Use leveling screws B and C to move the
bubble into the center of the level.
4. Rotate the alidade approximately 90°.
5. Use leveling screw A to move the bubble into
the center of the level.
6. Repeat Step 1 through Step 5 to center the
bubble in both positions.
7. Rotate the alidade 180°.
8. If the bubble in the plate level remains
centered, the instrument is level. If the
bubble moves off center, adjust the plate
level. For detailed instructions, see Checking and Adjusting the Plate Level,
page 142.
