Match the baud rate, parity, and data bits between your PC software and the TCR805 settings (accessible under MENU > SETTINGS > COMM ). Default settings are typically 19200 baud rate, 8 data bits, no parity.
The TCR805 features a user-friendly layout with a large, high-resolution LCD screen and a 31-key alphanumeric keypad. Key buttons include:
Look through the optical plummet (or activate the laser plummet).
: Clean lenses exclusively with anti-static microfiber clothes and professional lens fluid. Never use coarse paper or fingers. leica tcr805 total station user manual work
This comprehensive guide serves as an expanded, practical field manual to help you set up, calibrate, menu-navigate, and shoot data using the Leica TCR805. 1. Hardware Overview and Interface
Unlike older manual instruments that feature tangent screws with physical limits, the TCR805 utilizes endless horizontal and vertical drives. There are no clamps. You can rotate the instrument infinitely in either direction, allowing for rapid targeting. 2. Setting Up and Levelling the Instrument

5 arc-seconds, making it ideal for standard boundary surveys, construction layout, and topographic mapping.
Ensure that the optical or laser plummet aligns perfectly with the vertical axis. Set up the instrument over a fine cross drawn on a piece of paper. Rotate the instrument 180 degrees on its base. The laser dot should stay exactly on the cross center. If it tracks a small circle, the plummet requires physical calibration via the adjustment screws on its housing.
Before we dive into the user manual, let's take a look at some of the key features of the Leica TCR805: Key buttons include: Look through the optical plummet
: Turn on the electronic level by pressing the FNC key and selecting Level/Plummet . Align the housing parallel to two footscrews. Turn them in opposite directions until the electronic X-axis reads zero. Rotate the instrument 90 degrees and adjust the third footscrew until the Y-axis reads zero.
The TCR805 uses an RS232 serial cable (Leica GKL211). Modern laptops lack serial ports, so you need a with a Prolific chipset (cheap adapters cause parity errors).
Enter the Station Name (e.g., STN1 ) and input its coordinates ( E0cap E sub 0 N0cap N sub 0 H0cap H sub 0 ). Set instrument height ( ). Press . Select Orientation via Angle .
Up to 3,500m with a single prism or 400m in reflectorless mode using the integrated red laser.
Master the manual work, and the Leica TCR805 will reward you with decades of millimeter-accurate performance on every construction site, boundary survey, and topographic project you undertake.
