Leica: Tcr805 Total Station User Manual

Aim at a sharp, well-defined target roughly 100 meters away in Face 1 (Telescope normal). Take an angular reading.

Connect the proprietary Leica LEMO-to-USB or LEMO-to-RS232 serial cable to the instrument and your PC. Turn on the total station.

For land surveyors, civil engineers, and construction professionals, the represents a pivotal piece of heritage technology. Known for its robust build, accurate EDM (Electronic Distance Measurement), and onboard software, the TCR805 was a workhorse of the early 2000s. However, two decades later, one of the biggest challenges owners face is locating and interpreting the original Leica TCR805 Total Station user manual .

Select Prism if shooting a standard glass target, or Reflectorless if shooting directly at walls, rocks, or structures.
