Step 1: Initial Setup

1. Leveling and Centering: Begin by setting up the Total Station. Ensure it is properly leveled and centered at the station point.
2. Access the Menu: The Total Station menu has two main pages:
   • Start (includes options like setup, survey, apps, settings)
   • Manage
3. Navigate to Setup: Using the cursor, select the Setup option from the Start page, then press OK to proceed.

Step 2: Selecting Recession Mode

1. Press AF and Continue: After selecting setup, press the AF button to continue.
2. Select Recession: Use the cursor to navigate and select the Recession option. This mode allows you to establish station points by taking multiple measurements.

Step 3: Enter Station Point and Setup Parameters

1. Input Station Point Details: The Total Station will prompt you for the station point number or code. Enter the required code or let it auto-fill.
2. Select the First Point: If the first point is saved, you can enter its ID or select it from the list. This will be your primary point for setting up.

Step 4: Aligning with the Rod and Measuring Distance

1. Position the Instrument: Aim the Total Station toward the main rod on the first point and ensure the crosshairs are accurately aligned with the prism on the rod.
2. Measure Distance: Press the distance button to measure the distance to the rod. Once you have the measurement, press F3 to store the reading.

Step 5: Adding More Points for Recession

1. Select Additional Points: After storing the first measurement, your screen will display options for further points:
   • A1, F2, and F3 are options to measure additional points if needed.
2. Input ID for Second Point: If your second point has an ID, enter it directly. Otherwise, find it in the list.
3. Adjust to the New Point: Aim the instrument toward the rod at the second point, align the crosshairs, and press the distance button to measure.

Step 6: Store and Compute Measurements

1. Store Measurements: After measuring the second point, store the reading. You’ll see options like A2, A3, and A4 to add further points.
2. Select Tolerance and Compute:
   • F3 is for setting tolerance levels.
   • F4 is for computing the final values for your recession setup.

1. Finalize Recession: If you don’t need more points, select A4 to proceed. The screen will display the accuracy data, giving you insight into the precision of the measurements.

Step 7: Verifying Recession Accuracy

1. Stake Out to Check Accuracy: Go to the Stake Out mode and select a point from the recession survey.
2. Measure and Compare: Hit Distance to check if there is any difference. The Total Station will display the difference (in millimeters) to help you verify accuracy.
3. Re-adjust if Necessary: If there’s a significant discrepancy, you may need to re-target and measure.

Conclusion

Once you’ve checked the recession data and verified it, your setup is complete. You’re now ready to proceed with further measurements or site tasks.
