Loosen the central fixing screw slightly and slide the instrument on the tripod head to fine-tune the laser dot over the ground mark. Retighten and re-verify level. 3. User Interface and Menu Navigation
Rotate the alidade until the integrated electronic or plate vial is parallel to two of the tribrach footscrews.
Computes the surface area and perimeter of a polygon defined by real-time measurements or stored coordinates.
If you’re upgrading from an older manual total station, the TCR805’s interface will feel familiar but more powerful.
Before you can pick up topo points or stake out a grid, the total station must know where it is and which direction it is facing. Method 1: Orientation with Coordinates (Known Backsight) Go to the menu and select Surveying . Select Station Setup . Enter your Station ID, Instrument Height ( ), and the known Northing ( ), Easting ( ), and Elevation ( ) coordinates of the point the instrument is sitting on. Select Orientation and choose With Coordinates . Input the Backsight Point ID and its coordinates.
Open data transfer software, such as or modern open-source surveying transfer tools.

Regular maintenance protects your investment and ensures daily measurement integrity. User Field Calibration (Checking Errors)
If you cannot set up over a known point, you can set up anywhere and determine your position by measuring to two or more visible known control points. From the Programs menu, select .
Up to 200 meters (depending on target reflectivity and ambient light) using Leica’s PinPoint laser technology.
The Leica TCR805 saves data in the proprietary Leica GSI format. Exporting Files
To help you get the most out of your survey setup, could you share a bit more context? Please let me know:
The TCR805 features an alphanumeric keyboard and a large LCD for navigating its on-board software. Key software routines include: Measurement Modes:
Ensure the communication settings (Baud rate, Data bits, Parity) on your PC software match the settings inside the TCR805 menu (Standard is usually 9600 Baud, 8 Data Bits, No Parity).
Select the design point you wish to find from the internal memory or enter its coordinates manually. The screen will display
Connect the cable to the instrument's serial port and your computer's USB port. Power on the TCR805.
