4. Preparation for Surveying
4.1 Setting up the instrument
1Adjust the tripod legs so that a height suitable for surveying is obtained when the instrument is set on the tripod.
2A Set the tripod and fix the metal shoe firmly into the ground so that the tripod head is as level as possible and centered above the station point. If the tripod head is disturbed by the action of fixing the metal shoe into the ground, correct the level by extending or retracting each leg of the tripod.
