Using TSCe With Conventional Surveying Instruments

In Conventional, Surveying & Materials Testing | on August, 11, 2011 | by | 0 Comments

1. Setup the instrument over a point. Use the bulls-eye level on the tribrach to level the instrument. Remove the Geodimeter/ Trimble control unit.

2. Turn on the TSCe data collector. Ensure you are using the correct job.

3. From the main menu select Survey then select the appropriate survey style for your instrument.

4. Connect the TSCe to the instrument at the battery connector on the tribrach.  Wait for the TSCe to initialize the instrument.
TIP: If using an external battery, connect to the battery holder. If using a battery triple-pack, connect the TSCe to the same side as the battery cable is connected.

5. When the level instrument screen appears, level the instrument then tap Accept to engage the compensator.

6. Enter the appropriate barometric pressure and temperature. Tap Accept.

7. You are sent to the Survey Controller Basic screen. To set your plates to zero, tap Zero, then point at the center of your backsight target and tap Measure. Once the distance is measured, tap Esc.

8. From the main menu, select Survey\ (Survey Style)/ Station setup.  Check your corrections on the display, then tap Accept.
NOTE: 2 methods will be described here: Known coordinates for the occupied station and Unknown coordinates. 

Known Coordinates for Both Instrument Point and Backsight Point if the instrument and backsight points are already stored in the TSCe:

8. In the Instrument point name field, enter the station name, OR tap the arrow in the Instrument point name field, then select from the List.

9. In the Instrument height field, enter the HI.

10. In the Backsight point name field, enter a point number or select from the List. Trimble Survey Controller calculates the Azimuth and inserts it in the Azimuth field.

11. Choose an option in the Method field. (normally Angles and distance.)

12. Sight the center of the backsight target and tap Measure. The deltas shown are the differences between the calculated position and the observed position of the backsight.

13. Press Store to accept the station setup. Press ESC to return to the main menu.

Unknown Coordinates for Both Instrument Point and Backsight Point Coordinates to be provided later

14. In the Instrument point name field, enter the station name. The Survey Controller warns that the point is not in the database. Tap Continue.

15. In the Instrument height field, enter the HI.

16. In the Backsight point name field, enter a point number. Trimble Survey Controller warns that the point is not in the database and asks if you want to key it in. Tap Continue.

17. The value in the Azimuth field is null.

18. Choose an option in the Method field. (normally Angles and distance.)

19. Sight the center of the backsight target and tap Measure. The measurement information is displayed on the screen.

20. Tap Store to accept the Station setup. Station setup is complete. Tap ESC to return to the main menu.

NOTE: Coordinates may be keyed into the TSCe later, or may be entered into the software after downloading.
