Turn to Benchmark
11. This option should be used whenever you will be
shooting any benchmark other than the starting
benchmark. (The starting benchmark is always
the backsight for the first shot in a level loop.)
Enter the benchmark point in the BM Point field.
If this is a closing benchmark, this point must
already exist in the current job.
Shooting a benchmark other than the closing
benchmark is similar to shooting a turning point,
except the benchmark will either be stored as a
new point, or if the point already exists, the
elevation, or the elevation and coordinates can be
overwritten with the values from this routine.
12. Tap Next > to continue.
Note: If you are intend to shoot your closing benchmark and
accidentally tap Turn to Turning Point instead of Turn to Benchmark,
you can simply cancel out of that screen to return to the Level
screen and then make the correct selection.
13. If shooting a point that already exists, the Point
Exists screen will open.
If you are not shooting your closing benchmark,
tap Overwrite to overwrite the existing point
with the new computed elevation, or tap Use
Next to store the benchmark as a new point. You
will then return to the Level screen and will not
continue with the following steps.
If you are closing your level loop to this
benchmark, tap Close Loop By Existing Point to
continue.
14. The next screen will prompt you to take the
necessary shots as described in Step 7. Take the
shots and store the observation to continue.
