- Adjustment of Vertical cross hair: The vertical cross hair should lie in a plane perpendicular to the horizontal a×is.
- Adjustment of plate level a×es: The a×is of each plate level should lie in a plane perpendicular to the vertical a×is.
- Adjustment of line of sight: In a properly adjusted instrument, the line of sight is perpendicular to the horizontal a×is.
- Adjustment of horizontal a×is: The horizontal a×is is required to be perpendicular to the vertical a×is.
- Adjustment of the a×is of the telescope
- Adjustment of vertical circle inde×: The object of this adjustment is to set the vertical circle to zero when the line of sight is horizontal and the altitude bubble is centered.

Explanation:
When the theodolite is properly adjusted, the tangent to the plate bubble must be perpendicular to the vertical axis. This means that the bubble is centered between the two leveling screws, which ensures that the line of sight is vertical.
Theodolite adjustment involves aligning the horizontal and vertical axes of the instrument with the true horizon and the true zenith, respectively. Here are the steps involved in adjusting a theodolite:
1. Leveling the theodolite: The first step is to ensure that the theodolite is leveled using the two leveling screws. This is done by centering the bubble in the circular bubble vial, which is located on the base plate of the instrument.
2. Adjusting the vertical axis: The next step is to adjust the vertical axis of the theodolite by centering the bubble in the plate bubble vial. This is done by adjusting the two leveling screws located on the plate that holds the telescope.
3. Adjusting the horizontal axis: The final step is to adjust the horizontal axis of the theodolite by centering the bubble in the circular bubble vial again. This is done by adjusting the two leveling screws on the base plate of the instrument.
When the theodolite is properly adjusted, the following statements are true:
- The horizontal line passes through the center of the horizontal circle.
- The vertical line passes through the center of the vertical circle.
- The tangent to the plate bubble is perpendicular to the vertical axis.
In conclusion, the correct statement when the theodolite is properly adjusted is that the tangent to the plate bubble must be perpendicular to the vertical axis.
