Q1: What is a theodolite?
A1: A theodolite is a precision optical instrument for measuring angles between designated visible points in the horizontal and vertical planes. It is commonly used in surveying and engineering to obtain precise angular measurements.

Q2: What are the types of theodolites?

A2: Theodolites, instruments used in surveying and engineering to measure horizontal and vertical angles, come in several types, each designed for specific applications:

• Vernier Theodolite: Uses vernier scales for reading angles.
• Micrometer Theodolite: Uses micrometer screws for more precise measurements.
• Digital Theodolite: Incorporates electronic components to provide digital readings and often stores data internally or transmits it to external devices.
• Transit Theodolite: Allows the telescope to be rotated through the vertical plane.
• Non-Transit Theodolite: Does not allow full telescope rotation through the vertical plane.

Q3: What is the difference between a theodolite and a total station?

A3: While both theodolites and total stations are used in surveying and engineering applications to measure angles and distances, there are key differences between them:

• Theodolite: Measures horizontal and vertical angles only.
• Total Station: Combines theodolite functions with an electronic distance measurement (EDM) device, allowing it to measure angles and distances, and often includes data storage and processing capabilities.

Tips: How do you calibrate a digital theodolite?

To calibrate a theodolite, set it up on a stable tripod and level it using the foot screws and spirit level. Perform a collimation test by sighting a distant object, reversing the telescope, and noting any differences in readings. Adjust the crosshairs if needed. Check the vertical circle for index error by comparing readings of a horizontal plane from both telescope positions and adjust if necessary. Ensure the horizontal circle is accurate by rotating the instrument and sighting a fixed point at various positions. Recheck the levels and adjustments to confirm accuracy.
