Shoot From Two Ends
The Shoot From Two Ends screen is used to provide more accurate
vertical closure to a traverse. The routine requires that after the
foresight is shot, its location is not computed until after the
foresight point is occupied and a second shot is taken to the
previous occupy point. Once the second shot is complete, the
coordinates for the original foresight are computed from an average
of both shots.
1. From the Main Menu, select
6XUYH\ , 6KRRW )URP (QGV . If
you have not already setup your backsight, you will need to do
so before the Shoot From Two Ends screen will open.
2. Fill in the screen, including the number of sets that
you want to shoot from each point in the
Number of
Sets field.
3. Tap 7UDYHUVH , aim toward the backsight and tap
7DNH 6KRW .
4. Shoot the specified number of sets to the backsight and
foresight. When finished, the Move To Other End
dialog box will open, shown here. At this point you
need to move the total station over the current
foresight point, place a prism over the current occupy
point, fill in the dialog and tap OK. A new screen will
open.
5. Aim at the prism located over the previous occupy
point and tap
7DNH 6KRW . You will then need to shoot
the specified number of sets to the previous occupy point.
When the final set is complete, a screen will inform you of your new
occupy and backsight point and the new point will be computed and
stored.
