Check Shots - Leica DNA 10 Manual

DNA 10 Digital Level
Once the foresight shot on a benchmark or control point has been stored, continue the line
toward the next point or complete the loop by returning to the starting point. The instrument
person will move to a new location to take a backsight while the rod person stays at the
benchmark or control point.

3. Check Shots

While on the way back to close the loop, perform check shots on control points or flight line
targets that were collected on the first leg of the run. These check shots are also referred to
as intermediate shots or side shots. The purpose of the check shot is to verify that a level
"bust" has not occurred somewhere along the run. When the instrument is ready for the
foresight reading, the rod person will set the rod on the check point. After the check shot has
been taken, continue with the run by taking the next foresight.
When making a side shot measurement, make sure the low and high staff readings are within
set tolerances. Since the check shot will not affect the distance balance, the distance to the
side shot does not matter as long as it is less than the maximum distance. To perform a side
shot press the INT button (red oval).
