Electronic Digital Level

Quiz Question

1. The NA2000 represented a breakthrough in leveling techniques, using the innovative concept of reading a bar-coded staff. Due to its ease of use and high performance the digital level was quickly adopted by the market, which soon demanded a high accuracy instrument.
True
False
2. Figure 1 represents the _____________________.
Leica DNA03
Leica DNA06
3. The most conspicuous element of the DNA03/DNA10 is not the front panel, which accommodates an 8-line LCD display and a keyboard with full alphanumerical capabilities.
True
False
4. The position of the measure button on the right hand side of the instrument Leica DNA03 was moved to the centre of the instrument body in order to minimize the impact on the instrument when pressing the button.
True
False
5. The DNA03 and DNA10 do not use a magnetically damped compensator based on the model used in the NA3003.
True
False
6. In the DNA03staff image is captured by a new high sensitivity CCD linear sensor that is sensitive in the visible light spectrum. The incoming light is split into a portion for the visual measurement (visual path) and a portion for the electronic measurement (CCD).
True
False
7. The light from incandescent or halogen lamps is not suitable for the staff illumination when measuring in dark conditions.
True
False
8. The process of the single measurement consists of __________________ events.
Two
Three
Four
9. The typical time for the coarse and fine correlation is about_________________.
1.5seconds
1.5 micro seconds
10. The resulting typical time for a single measurement is 3sec.
True
False
11. There is a different field of view for coarse and fine correlation – For the fine correlation the full field of view of 2° is required in the distance range up to 50m. For the coarse correlation a typical field of view angle of 1.1° is used.
True
False
12. The measure modes implemented in the NA3003 were well accepted by the users. These modes are also found in the DNA03 and DNA10. They consist of the single measurement, the mean mode, the median, and the mean mode with predefined standard deviation.
True
False
13. The DNA03 and DNA10 are the first digital levels that are equipped with a display with the dimensions of 8 lines at 24 characters..
True
False
14. The displays of the DNA10 and DNA03 are not identical to the one of the TPS700 instruments.
True
False
15. The keyboard structure of the DNA03 and DNA10 is not similar to the TPS700 series.
True
False
16. Differences between the DNA10 and DNA03 from the TPS700 include-
• ESC being on a single key for fast exiting of the displays and
• DATA being on a single key for immediate access to the data manager.
True
False
17. The data storage concept of the DNA10 and DNA03 is based on the TPS700. The measurement data is automatically stored in a binary format in an internal memory with a capacity of approximately 6000 measurements.
True
False
18. When the DNA03 and DNA10 are turned on the instruments will immediately be ready for measuring a back sight or simply measuring a staff reading repeatedly. Due to the large display all the necessary information of the measurement can be shown on one screen, which is very comfortable as toggling to other displays is not necessary anymore.
True
False
19. Figure 5 represents the __________________.
Measure & Record display
Keyboard of the DNA03 and DNA10
20. The DNA10 does not have the four established line leveling applications BF, aBF, BFFB and aBFFB built in.
True
False
21. The DNA03 and DNA10 offer __________ possibilities for storing codes.
Two
Three
Four
22. Figure 8 represents _____________________.
NA3003 single measurements at dusk
DNA03 single measurements at dusk
23. The DNA03 and DNA10 do not store information like: job, line, measure mode, corrections, start point, measurement, target point, station results and more.
True
False
24. The_____________ are implemented as standard formats.
XML
GSI-8
GSI-16
All of the three
None of the three
25. LevelPak-Pro is the latest generation of software for importing, processing, reporting and exporting Leica digital level data.
True
False
