Slope Staking Offset Stake
The following screens are only accessed if you choose to stake a point
at a specified offset away from the catch point.
Station: displays the current station being
slope staked.
Offset from CP: is the offset from the catch
point specified in the previous screen.
From Gun to Design Point: displays the angle
and distance information from the total station
to the design point.
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 the current
target, 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 current target location.
3. To prevent errors if this button is used, the backsight set up
is invalidated when exiting the Stakeout dialog. 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.
< Back : returns to the previous screen.
Stake > : opens the next screen, which is identical to the third Stake
Points screen, described on Page R-276.
