Stakeout Menu

Stake Points – Screen Two
Design point: displays the name of the design
point that was entered in the first screen.
Description: displays the description assigned
to the design point.
Angle Right: is the horizontal angle to turn to
face the design point.
Horz. distance: is the horizontal distance from
the occupy point to the design point.
Vert Distance: is the vertical distance from the
occupy point to the design point.
ZE to Rod: is the zenith angle required to face the prism over 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 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.
