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

R

ight

or

L

eft 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.

&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.
