Centering using a plumb bob

Set up the instrument on the tripod. For detailed instructions, see

Tripod, page

Hang the plumb line on the hook of the tripod mounting screw.

Adjust the length of the plumb line so that the tip of the plumb bob is at the

height of the station point.

Loosen the tripod mounting screw slightly.

Using both hands to support the outer side of the tribrach, carefully slide the

instrument about on the tripod head until the tip of the plumb bob is positioned

over the exact center of the station point.

Note – To confirm that the instrument is precisely aligned, check its position from two

directions at right angles to each other.

When you level the instrument, you make the vertical axis of the instrument exactly

vertical. To level the instrument, use the electronic level. In the leveling work, always

set the instrument in face 1 direction (please refer to the Fig.1.1 in page 3).

To level the instrument:

Move the bubble into the circle drawn on the

circular level and then turn on the power.

Rotate the alidade until the bottom edge of

the keyboard panel is parallel to the two of

the leveling screws (B and C).

Use leveling screws B and C to move the

bubble into the center of the electronic level.

Rotate the alidade approximately 90°.

Use leveling screw A to move the bubble into

the center of the electronic level.

Repeat Step 1 through Step 5 to center the

bubble in both positions.

Rotate the alidade 180°.

If the bubble in the electronic level remains

centered, the instrument is level. If the

bubble moves off center, adjust the electronic

level. For detailed instructions, see

the Electronic Level, page
