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. |

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. |
