Spectra Precision Survey Pro v4.9 - Manual (Page 158)

Offset from CP: is the offset from the catch point specified in the previous screen.
From Instrument to Design Point: displays the angle and distance information from the total station to the design
point.
[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 the current target, 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 current target location.
3. To prevent errors if this button is used, the backsight set up is invalidated when exiting the Stakeout dialog. 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.
[< Back]: returns to the previous screen .
[Stake >]: opens the next screen, which is identical to the third Stake Points screen.
Point Slope Staking
[Stakeout] [Point Slope Staking]
The Point Slope Staking routine is a simplified version of the Slope Staking routine.
The Point Slope Staking routine determines the location of the catch point from a known hinge point and a specified
horizontal direction from the hinge point, whereas the Slope Staking routine determines the location of the catch point
from a perpendicular offset to a known centerline at a specified station.
The first screen is used to specify the hinge point and horizontal direction from the hinge point to the catch point.
[From Point]: is the hinge point.
[> Point] / [> Direction]: is either another point that lies in the same vertical plane as the hinge point and catch point,
or the azimuth from the hinge point to the catch point, respectively.
Fill Slope: is the desired slope, calculated from run over rise, between the hinge point and catch point when the area
requires a fill.
Cut Slope: is the desired slope, calculated from run over rise, between the hinge point and catch point when the area
requires a cut.
Height of Rod: is the rod height.
[Backsight…]: opens the Station Setup screen.
[Stake CP >]: opens the next screen .
