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
R ight or L eft 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.
&LUFOH =HUR : 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 &LUFOH =HUR button is not available when using a robotic
total station.
%DFN : returns to the previous screen.
