Collecting Elevations in a Simple Level Loop
After creating/selecting a loop, Survey Pro prompts you to start collecting
elevations in the loop. A new screen is displayed providing the list of possible
actions. The name of the open level loop is indicated in the upper bar.
NOTE: The button provides access to the level settings (see Level Settings on
page 35).
Follow the procedure below to complete a typical level loop:
1. Set up your instrument midway between the opening CBM and the first
turning point and have your rods ready for backsight and foresight
observations.
2. Unless already done, select Survey from the main menu, then Level.
3. Tap Turn to Turning Point. Based on the shooting sequence you have chosen,
Survey Pro will prompt you successively to take all the necessary direct and
reverse shots to the backsight point (the opening CBM) and the foresight
point (the first turning point in the level loop).
If in manual leveling, you will be requested to enter the following
parameters measured with your standalone instrument:
4. After completing the shooting sequence, Survey Pro will show the results.
Tap Store Observation if you are satisfied with the results. If these are of poor
quality you can remove some of them (use the Toss button) or add new
backsight ( BS) and/or foresight (FS) observations.
5. After you have tapped Store Observation, thus accepting the results, Survey
Pro will prompt you to start a second level turn.
NOTE: As you move along the loop, at the end of each level turn, Survey Pro provides
an up-to-date summary of the measurements made so far (total number of level
turns made, etc.)
If you tap on the Notes vertical tab, you will see a summary of all the measurements
made so far.
