Repetition Shots Screen
After the repetition settings are configured, the Repetition Shots
screen is accessed where the actual shots are performed.
1. Select . Survey , Repetition Shots from the
Main Menu. If you have not already set up
your backsight, you will need to do so
before you can access the Repetition Shots
screen.
2. Enter the Foresight point name, Number of
Sets
and HR in the appropriate fields.
3. Tap the All button to start the process of
shooting all of the sets using the sequence
selected in the Repetition Settings screen.
4. Prompts will open after every shot that instruct you on which
point to shoot next and when you when you need to flop the scope.
If at least three sets were performed, the Average and Worst Residual
fields will be filled in after the final shot is taken. The Average
values are simply average measurements for all of the shots taken.
The Worst Residual is the angle or distance measurement that varied
the most from the average of all shots taken.
5. Optional – The particular measurement with the worst residual
can be removed and consequently not used when computing the
coordinates for the foresight point by tapping the corresponding
Toss button. After tossing a measurement, the Average (of) and
Worst Residual
values are recomputed (assuming there is still
data from at least three shots remaining).
6. Optional – You can re-shoot the specified number of sets, and only
collect the horizontal angle, zenith angle, or slope distance from
all the shots by tapping the HA, ZA, or SD button, respectively.
This will replace all of the current shot data only for the selected
data type with new data. You can even change the number of
sets before shooting the new data.
7. Once you are satisfied with your shot data, tap Side Shot to store
the new foresight point as a side shot, or tap Traverse to store it
as a traverse shot.
