: Verify the red laser dot matches the ground point exactly. Slide the instrument across the tripod head to adjust if necessary, then re-verify level. 3. Job Creation and Station Orientation
In the age of robotic total stations and GPS rovers, the Leica TCR805 remains a workhorse in the construction and surveying industries. Known for its rugged durability, reflectorless measurement (hence the "R" in TCR), and reliable angle accuracy, this instrument is still widely used for topographic surveys, construction layout, and monitoring projects.
Adjust the tripod legs to shift the laser dot directly onto the ground point. 3. Precision Leveling
After powering on the instrument, press the key from the surveying menu. Here, you can either "Select a Point" from the coordinate file or manually enter the coordinates of your survey station (X, Y, Z). leica tcr805 total station user manual work

, which automatically corrects leveling inaccuracies, ensuring precise vertical and horizontal angle measurements even on uneven terrain. Its key features include: 30x magnification for clear long-distance sighting. Internal memory capable of holding up to 18,000 points , reducing the need for external data loggers in the field. Versatility: Supports both prism and reflectorless (RL) modes
Press (F4). The TCR805 will display its calculated position alongside the statistical accuracy errors (Standard Deviation). If acceptable, press Set to store the station coordinates.
