Stake Spiral and Offset – Screen
Three
Station: displays the current station that is being
staked.
H. Offset: displays the offset distance of the spiral curve
being staked from the specified spiral curve and if it is
on the Right or Left side of the specified spiral curve.
Angle Right: is the horizontal angle that the total
station must aim toward so that it is facing the current
station.
Horz Dist: is the horizontal distance from the occupy
point to the current station.
Vert Dist: 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.
