Test the electronic level and the plummet periodically.
is a high-precision surveying instrument designed for construction, engineering, and tacheometry. : Offers 5-second angular accuracy. Magnification : 30x telescope magnification.
At the end of the day, your field data needs to be safely transferred to a computer for CAD drafting or GIS analysis.
Aim the telescope precisely at your backsight target (e.g., a reference pin or distant landmark).
: Offers 5-second angular accuracy and can measure up to 12,000 feet with a single prism or 300–984 feet in reflectorless (prismless) mode.
The TPS800 series manual highlights several embedded programs: Standard data collection.
: The unit is noted for its ability to withstand wet weather and tough field conditions, reducing downtime during inclement weather.
Download and export the data into your required format, such as , DXF (for CAD processing), or TXT/CSV (for spreadsheet analysis). 8. Maintenance and Calibration Tips
The TCR805 is designed for high-performance field applications, with specifications that balance range and accuracy: Leica Total Station 805 - sciphilconf.berkeley.edu
The TCR805 uses Leica GEB111 or GEB121 NiMH batteries. Avoid leaving them completely drained for long periods. Store them with a partial charge in a cool, dry place.
Input the Point ID (e.g., 100 ) and the Point Code/Description (e.g., TREE , CURB , WALL ).
The Leica TCR805 User Manual provides detailed steps for instrument setup and basic functions:
With setup complete, you are ready to collect data using either Topographic Surveying or Stakeout modes. Topographic Surveying (Data Collection) Navigate to the program from the main menu.
