    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.

    High accuracy
    The theodolite is aways!! Plenty of features and accuracy for most any commercial construction site. Easy to use and just does what we wanted.
