Curve and Offset – Screen 3
Station: displays the current station that is being staked.
H. Offset: displays the offset distance of the curve being staked from the specified curve and if it is on the Right or
Left side of the specified curve.
Angle Right: is the horizontal angle that the total station must aim toward so that it is facing the current station.
Horz. distance: is the horizontal distance from the occupy point to the current station.
Vert Distance: is the vertical distance from the occupy point to the current station.
ZE to Rod: is the zenith angle that the total station must aim toward so that it is facing the current station.
[Circle Zero]: is used to modify the circle on the total station so that the angle right reading will be zero when it is
facing toward the design point, which can sometimes be easier than turning to an obscure angle value. When this
button is tapped, the following actions will occur:
1. A new backsight circle value is computed, sent to the instrument and stored in the raw data.
2. The Angle Right value is changed to zero to reflect the change. The instrument now needs to be turned
horizontally to zero to face the design point.
3. To prevent errors, the backsight set up is invalidated when exiting the Stakeout dialog if this button has been
used. A circle zeroed on a design point is meaningless once the design point has been staked.
Note: The [Circle Zero] button is not available when using a robotic total station.
[Stake >]: opens the next screen, which is identical to the third
