1. Set up the theodolite at the starting point of the traverse and level it using the built-in bubble level.
2. Sight the first point in the traverse and record the horizontal and vertical angles measured by the theodolite.
3. Move the theodolite to the next point in the traverse and repeat the process of sighting and recording angles.
4. Continue this process for all points in the traverse, ensuring that the theodolite is properly leveled and sighted at each point.
5. Calculate the coordinates of each point in the traverse using the measured angles and distances between points.
6. Check the closure error of the traverse by comparing the calculated coordinates of the starting and ending points. Adjust the angles and distances as necessary to minimize the error.
7. Make any necessary adjustments to the angles and distances in the traverse to ensure that the closure error is within an acceptable tolerance.
8. Repeat the process of measuring angles and distances, calculating coordinates, and adjusting as needed until the closure error is minimized and the traverse is accurately completed.
9. Record the final coordinates of each point in the traverse and create a final map or drawing of the traverse.

Sequence of Steps for Computing and Adjusting Theodolite Traverse:
1. Measure and Record Field Data: Measure the horizontal angles, vertical angles, and distances along the traverse lines using a theodolite and tape or EDM. Record all observations in a field notebook.
2. Compute Azimuths: Compute the azimuths of each traverse line using the observed horizontal angles and the starting azimuth.
3. Compute Coordinates: Calculate the easting (X) and northing (Y) coordinates of each traverse station using the azimuths and distances.
4. Balance the Angles: Check for any angle closures or errors. If the angle closure is significant, adjust the measured angles using the least squares method to obtain balanced angles.
5. Balance the Distances: Check for discrepancies in the measured distances. If significant, adjust the distances using the least squares method to obtain balanced distances.
6. Compute Adjusted Coordinates: Recalculate the easting and northing coordinates using the adjusted angles and distances.
7. Computations of Latitudes and Departures: Obtain the latitudes (Lf) and departures (Df) for each traverse line using the adjusted coordinates.
8. Adjustment of Latitudes and Departures: Check for any closure errors in latitudes and departures. If significant, adjust the latitudes and departures using the least squares method.
9. Final Adjusted Coordinates: Compute the final adjusted coordinates (Easting and Northing) using the adjusted latitudes and departures.
10. Closure Calculation: Determine the linear and angular closures to assess the accuracy of the adjusted traverse. The linear closure should be less than 0.05%, and the angular closure should be less than 30".
