What is a Theodolite and How Does It Work?
A theodolite is a device that measures horizontal and vertical angles between two points. It consists of a telescope mounted on a horizontal axis (called the trunnion axis) and a vertical axis (called the vertical axis). The telescope can rotate around both axes independently, allowing it to point at any direction in space. The angles are read from graduated circles attached to each axis, which can be magnified by a micrometer for more precision.
The basic principle of a theodolite is simple: it uses trigonometry to calculate distances and heights based on angles. For example, if you know the horizontal angle between two points on the ground (such as two landmarks) and the distance between them (such as measured by a tape or a chain), you can use a formula to find out their elevation difference. Similarly, if you know the vertical angle between two points (such as a point on the ground and a point in the sky) and their horizontal distance (such as measured by a theodolite), you can use another formula to find out their height difference.
Theodolites can be used for various purposes, such as mapping, surveying, engineering, construction, geodesy, astronomy, meteorology, and more. They can also be combined with other instruments, such as levels, transits, compasses, plumb bobs, tripods, and electronic devices, to enhance their functionality and accuracy.

and a dust cover for protecting the instrument from dust and moisture.
How to Use Carl Zeiss Jena Theo 010A and Theo 010B?
Carl Zeiss Jena Theo 010A and Theo 010B are easy to use once you get familiar with their parts and functions. Here are some general instructions and tips on how to use them properly.
How to Set Up the Theodolite
To set up the theodolite, you need a stable and level tripod and a point on the ground that you want to center the instrument over. Follow these steps:
Attach the theodolite to the tripod by screwing the base of the instrument onto the tripod head.
Adjust the height of the tripod legs so that the instrument is at a comfortable level for your eye.
Loosen the horizontal clamp and rotate the instrument until the plumb bob is directly over the point on the ground. Tighten the horizontal clamp.
Loosen the vertical clamp and tilt the telescope until it is horizontal. Tighten the vertical clamp.
Check if the bubble levels are centered. If not, use the leveling screws to adjust them until they are centered.
The instrument is now set up and ready for use.
How to Level the Theodolite
To level the theodolite, you need to make sure that both bubble levels are centered. This ensures that the horizontal and vertical axes are perpendicular to each other and to the gravity vector. Follow these steps:
Loosen the horizontal clamp and rotate the instrument until one of the plate levels is parallel to a pair of leveling screws. Tighten the horizontal clamp.
Use the pair of leveling screws to adjust the plate level until it is centered.
Loosen the horizontal clamp and rotate the instrument by 90 degrees until another plate level is parallel to another pair of leveling screws. Tighten the horizontal clamp.
Use the other pair of leveling screws to adjust the other plate level until it is centered.
Repeat steps 1-4 until both plate levels are centered in all directions.
Check if the circular level is also centered. If not, use any of the leveling screws to adjust it until it is centered.
The instrument is now leveled and ready for measuring angles.
How to Measure Horizontal and Vertical Angles
To measure horizontal and vertical angles, you need to point the telescope at two points in space and read their angular difference from the graduated circles. Follow these steps:
Loosen the horizontal clamp and rotate the instrument until the telescope points at one of the points (such as a landmark or a star). Tighten the horizontal clamp.
Loosen the vertical clamp and tilt the telescope until it points at one of the points (such as a landmark or a star). Tighten the vertical clamp.
Read and record all four micrometer readings from both circles. These are called the first readings.
Loosen both clamps and move the telescope to point at another point in space.
Tighten both clamps and read and record all four micrometer readings from both circles again. These are called the second readings.
Subtract each first reading from its corresponding second reading. The results are called the angular differences.
Average each pair of angular differences from each circle. The results are called the mean angular differences.
The mean angular difference from the horizontal circle is the horizontal angle between the two points. The mean angular difference from the vertical circle is the vertical angle between the two points.
How to Read the Micrometer
To read the micrometer, you need to align your eye with one of the verniers and one of the micrometers. Follow these steps:
Look through one of the eyepieces of the micrometer and find the vernier that corresponds to it.
Note the number on the graduated circle that is aligned with the zero mark on the vernier. This is called the coarse reading.
Find the mark on the vernier that is aligned with a mark on the graduated circle. Note the number on the vernier that corresponds to it. This is called the fine reading.
Add the coarse reading and the fine reading together. The result is called the micrometer reading.
Repeat steps 1-4 for all four micrometers.
How to Adjust the Theodolite
To adjust the theodolite, you need to calibrate and correct some of its parts and functions. This ensures that the instrument is accurate and error-free. Follow these steps:
Adjust the eyepiece of the telescope until you can see the reticle clearly and sharply.
Adjust the focus of the telescope until you can see the object clearly and sharply.
Adjust the illumination device until you can see the graduated circles and the micrometers clearly and brightly.
Check if the telescope is collimated (i.e., if its optical axis is aligned with its mechanical axis). To do this, point the telescope at a distant object and read its horizontal angle. Then, invert the telescope by 180 degrees and read its horizontal angle again. If the two readings are equal, the telescope is collimated. If not, use the collimation screws to adjust it until they are equal.
Check if the horizontal circle is oriented (i.e., if its zero mark is aligned with the north-south direction). To do this, use a compass or a known direction to find the north-south line. Then, loosen the horizontal clamp and rotate the instrument until the zero mark on the horizontal circle is aligned with the north-south line. Tighten the horizontal clamp.
Check if the vertical circle is zeroed (i.e., if its zero mark is aligned with the horizontal plane). To do this, loosen the vertical clamp and tilt the telescope until it is horizontal. Then, read and record all four micrometer readings from the vertical circle. If they are all zero, the vertical circle is zeroed. If not, use the zeroing screws to adjust it until they are all zero.
