3. PREPARATION FOR SURVEYING

3.1 Centering and leveling of the instrument

[Setting up the instrument and the tripod]

Adjust the tripod legs so that a height suitable for observation is obtained when the

instrument is set on the tripod.

Hang the plumb bob on the hook of the tripod,and coarse center over the station on

the ground.At this time,set the tripod and fix the metal shoes firmly into the ground

so that the tripod head is as level as possible,and the plumb bob coincides with the

station on the ground.

If the tripod head is mis-leveled by the action of fixing the metal shoes into the

ground,correct the level by extending or retracting each leg of the tripod.
