Vert Distance: is the vertical distance from the occupy point to the
design point.
ZE to Rod: is the zenith angle required to face the prism
over 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 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.
4. The first time Circle Zero is used during a stakeout session, a
dialog will appear to warn that the original backsight
reference will be lost.
Note: The Circle Zero button is not available when using a robotic
total station.
< Back : returns to the first screen.
Stake > : accesses the third and final Stake Points screen where the
shots to the stake point are performed.
