Curve and Offset – Screen Three
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.
