Leica Tcr805 Total Station User Manual Work Jun 2026

Triggers the EDM to measure a distance without saving the data point.

: To configure for external software like Carlson SurvCE , hold the Menu button for 2 seconds, navigate to Rec Data or Communication Parameters , and set the Baud rate (e.g., 19200) and Parity. Integrated Software Programs

: If you are set up over a point with known coordinates, you select Set Station from the Surveying menu. You then enter the station coordinates, instrument height, and target height. The final step is to orient the instrument to a backsight point with a known direction, setting the horizontal circle to the correct azimuth.

is a high-precision surveying instrument designed for construction, engineering, and tacheometry. : Offers 5-second angular accuracy. Magnification : 30x telescope magnification.

Temperature swings can shift the relationship between the telescope's optical axis and the electronic encoders. Go to ➔ Calibration . leica tcr805 total station user manual work

Example: Control setup for small site (assume metric)

The TCR805 is not just a measuring tool; it is a field computer with several onboard programs to enhance productivity and reduce post-processing work.

If you need a specific checklist for setting up on a new site, or help with the data transfer process, just let me know!

: The TCR805 allows users to perform their own calibration using the "Check & Adjust" function. This simple, guided process determines and corrects for minor instrument errors (e.g., in the compensator or line of sight) that can develop over time. A user calibration is recommended every three to six months , before high-precision surveys, or after long or rough transportation. Triggers the EDM to measure a distance without

Mount the TCR805 onto the tripod head and secure the central fixing screw.

: Place the TCR805 on the tripod head. Secure the central fixing screw underneath.

Use this method when you cannot set up over a known point, but have visibility to two or more distant known control points. Set up the instrument at an arbitrary, convenient location. In the menu, select Resection .

Create a new "Job" or select an existing one to store your points. You then enter the station coordinates, instrument height,

Use the foot screws to level the instrument until the electronic level shows all parameters within an acceptable range.

Press (Record) or DIST + REC . The instrument calculates the orientation orientation angle. Method 2: Resection (Free Stationing)

: 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.
