1. Choose a suitable location for setting up the theodolite, ensuring it is on stable ground and free from obstructions.
2. Level the theodolite using the built-in bubble level or a separate leveling device. Adjust the tripod legs as necessary to ensure the theodolite is perfectly level.
3. Secure the theodolite to the tripod using the mounting screw or clamp, making sure it is firmly attached and stable.
4. Set up the tripod at the desired height, making sure it is secure and stable.
5. Attach the optical plummet to the theodolite and use it to center the theodolite over the point where measurements will be taken.
6. Turn on the theodolite and calibrate it according to the manufacturer's instructions. This may involve setting the horizontal and vertical zeros, adjusting the focus, and setting the desired units of measurement.
7. Use the theodolite to take measurements by sighting through the telescope and reading the angles displayed on the horizontal and vertical scales.
8. Record the measurements accurately and use them to calculate distances, elevations, and other surveying data as needed.
9. When finished, carefully pack up the theodolite and tripod, making sure to protect them from damage during transportation.

Procedure for Setting Out a Theodolite:
1. Preparation:
- Check the theodolite for any damage or defects.
- Set up a stable and level tripod at the desired location.
- Attach the theodolite to the tripod and tighten it securely.
2. Levelling the Theodolite:
- Use the built-in spirit level or external level vial to level the theodolite in both directions (horizontal and vertical).
- Adjust the foot screws of the tripod to bring the bubble centered.
3. Centering the Theodolite:
- Use a plumb bob or laser plummet to center the theodolite exactly over the survey station.
- Adjust the tripod legs or telescope to ensure that the plumb bob or laser dot is directly over the mark on the ground.
4. Orienting the Telescope:
- Sight on a distant, well-defined object or mark in the direction of the desired survey line.
- Rotate the alidade of the telescope to zero the horizontal circle (or vernier).
5. Setting the Vertical Angle:
- Depending on the requirements, set the vertical angle of the telescope to the desired elevation (e.g., for level work, set it to 0°).
- Use the vertical circle (or vernier) to align the crosshairs with the target.
6. Checking and Re-Adjusting:
- Recheck the leveling, centering, and orientation of the theodolite.
- Make any necessary fine adjustments to ensure accuracy.
7. Reading the Angles:
- Once the theodolite is correctly set out, take readings from the horizontal and vertical circles (or verniers) as required for the survey work.
- Note the values carefully and record them in the field book.
8. Dismantling the Theodolite:
- Carefully dismantle the theodolite in the reverse order of setup.
- Protect the instrument from damage during transportation.
