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.
Note: The Circle Zero button is not available when using a robotic
total station.
