Guide the rodperson until the distance discrepancy is zero, then mark the ground. 6. Data Transfer and Office Processing
Set a descriptive code for the object (e.g., TREE , CURB , WALL ). Sight the target using the optical crosshairs.

Use the leveling screws and the electronic bubble shown on the display to level the instrument. The TCR805 has an electronic level for high precision.
Use a tape measure to measure the distance from the ground peg to the center mark on the side of the TCR805. Input this value into the instrument. Orientation via Backsight Select Set Orientation from the menu.
