Leica Tcr805 Total Station User Manual Work [extra Quality] May 2026

The Leica TCR805 Total Station is a cornerstone of the Leica TPS800 series, known for its precision, durability, and user-friendly interface. Whether you are a seasoned surveyor or a student, understanding how to operate this instrument effectively is crucial for accurate data collection. This guide serves as a comprehensive overview of the Leica TCR805 workflow, covering everything from initial setup to data export. Understanding the Leica TCR805 Interface

Reflector Mode (IR): Used with standard prisms. This provides the highest accuracy and longest range. It is ideal for boundary surveys and high-precision construction layout.Reflectorless Mode (RL): Allows you to measure distances to almost any surface (walls, power lines, cliffs) without a prism. This is a game-changer for measuring inaccessible points or increasing speed on a busy site.

Secure the TCR805 onto the tripod head using the centering screw. leica tcr805 total station user manual work

Turn on the instrument and use the electronic level (digitized bubble) for fine leveling. Adjust the tribrach footscrews until the tilt error is within acceptable limits (usually less than 5 seconds).

Extend the tripod legs to a comfortable height and ensure the tripod head is roughly level. The Leica TCR805 Total Station is a cornerstone

To maintain the TCR805’s accuracy, regular maintenance is required. Always store the instrument in its hard case when not in use. Avoid exposing it to extreme temperature fluctuations or moisture.

The TCR805 typically uses a serial connection (RS232) or a specialized Leica USB data cable. Using software like Leica Geo Office (LGO) or Leica Infinity, you can "Download" the job file. Common export formats include GSI, DXF, and CSV. Maintenance and Calibration This is a game-changer for measuring inaccessible points

Before taking measurements, you must define where the data will be stored and where the instrument is located in space. Navigate to the "Programs" menu and select "Setup."

To switch between modes, use the "EDM Settings" menu. Always ensure the correct "Prism Constant" is entered when using reflectors to avoid systematic errors. Common Surveying Workflows

Precision begins with a stable setup. Follow these steps to ensure your instrument is ready for work:
