The Leica TCR805 Total Station is a cornerstone of the Leica TPS800 series, known for its precision, durability, and user-friendly interface. Whether you are a seasoned surveyor or a student, understanding how to operate this instrument effectively is crucial for accurate data collection. This guide serves as a comprehensive overview of the Leica TCR805 workflow, covering everything from initial setup to data export. Understanding the Leica TCR805 Interface

The TCR805 features a clear, monochrome display and an alphanumeric keyboard. The interface is menu-driven, allowing users to navigate through various functions using the arrow keys and function buttons (F1-F4).

The "Measure" screen is your primary workspace. Here, you can view horizontal angles, vertical angles, and slope distances. The function keys at the bottom of the screen change depending on the active menu, providing quick access to distance measurements (DIST), data recording (REC), and electronic leveling tools. Initial Instrument Setup and Leveling

Precision begins with a stable setup. Follow these steps to ensure your instrument is ready for work:

Extend the tripod legs to a comfortable height and ensure the tripod head is roughly level.

Secure the TCR805 onto the tripod head using the centering screw.

Use the circular bubble level on the tribrach for initial leveling by adjusting the tripod legs.

Turn on the instrument and use the electronic level (digitized bubble) for fine leveling. Adjust the tribrach footscrews until the tilt error is within acceptable limits (usually less than 5 seconds).

If you are setting up over a specific point, use the laser plummet to align the instrument exactly over the ground mark. Setting the Job and Station

Before taking measurements, you must define where the data will be stored and where the instrument is located in space. Navigate to the "Programs" menu and select "Setup."

Create a new "Job" or select an existing one to store your points.

Select "Set Station" to input the coordinates (X, Y, Z) and instrument height of your current location. If you are working on a local grid, you can start with arbitrary coordinates like 1000, 1000, 100.

Perform a "Backsight" measurement. This involves sighting a known point or setting an orientation angle (Azimuth) to establish the direction of the coordinate system. Measurement Modes: IR vs. RL

One of the standout features of the TCR805 is its Reflectorless (RL) capability.

Reflector Mode (IR): Used with standard prisms. This provides the highest accuracy and longest range. It is ideal for boundary surveys and high-precision construction layout.Reflectorless Mode (RL): Allows you to measure distances to almost any surface (walls, power lines, cliffs) without a prism. This is a game-changer for measuring inaccessible points or increasing speed on a busy site.

To switch between modes, use the "EDM Settings" menu. Always ensure the correct "Prism Constant" is entered when using reflectors to avoid systematic errors. Common Surveying Workflows

The TCR805 is equipped with several onboard software programs to streamline common tasks: Data Management and Export

Data is stored internally on the instrument's memory. Once your field work is complete, you will need to transfer this data to a computer for processing in CAD or surveying software.

The TCR805 typically uses a serial connection (RS232) or a specialized Leica USB data cable. Using software like Leica Geo Office (LGO) or Leica Infinity, you can "Download" the job file. Common export formats include GSI, DXF, and CSV. Maintenance and Calibration

To maintain the TCR805’s accuracy, regular maintenance is required. Always store the instrument in its hard case when not in use. Avoid exposing it to extreme temperature fluctuations or moisture.

Periodically perform a "Check and Adjust" routine, which is an onboard program that guides you through calibrating the horizontal collimation and tilting axis inclination. If the instrument suffers a significant bump or drop, it should be sent to a certified Leica service center for professional calibration.

It is part of the Leica TPS800 series, which also includes the TCR802 and TCR803. Core Operations and Setup

The Leica TCR805 User Manual provides detailed steps for instrument setup and basic functions:

Setup and Leveling: Use the detachable tribrach and integrated electronic level to stabilize the unit. The display will show arrows indicating which foot screws to rotate until a checkmark appears, confirming the unit is perfectly leveled. Measurement Modes:

IR Mode: Uses a visible coax laser for measurements with a reflector.

RL/RL-Prism: Provides reflectorless measurement up to 984 feet (300m) using a narrow red laser beam.

Keypad Navigation: Use the sidecover on/off key to power the unit. Navigate menus using the alphanumeric and function keys, which correspond to softkey commands at the bottom of the screen. Data Management and Connectivity

The TCR805 includes internal memory and interface options for external data handling:

Internal Storage: Can store up to 8,000–16,000 points depending on the specific model and firmware.

Data Transfer: Connect to a PC or data collector via the RS-232C serial interface.

Communication Settings: 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

The unit comes with onboard programs for standard surveying tasks:

Orientation and Stationing: Setting coordinates and horizontal circle orientation.

Surveying Tasks: Includes area computation, tie distance (missing line), and reference line offsets.

Setting Out: Direct guidance for positioning points on a construction site. Leica Builder Series How to Guide - FLT Geosystems

Method A: Known Point Orientation (Occupation)

  1. Enter PROG > Survey > Set Orientation.
  2. Enter your station coordinates (N, E, Z).
  3. Enter the backsight point coordinates.
  4. Aim at the backsight prism. Press ALL (All measure).
  5. The instrument calculates the horizontal angle difference. Press SET to lock.

Manual Warning: Always check by sighting a third known point. Measure the distance. If the error is >0.02 m + (5 ppm × distance), redo your setup.

Conclusion: From Manual Work to Professional Excellence

The Leica TCR805 total station user manual work is not a one-time read. It is a living document that you will reference throughout the instrument’s life. By systematically working through the chapters on leveling, soft key logic, reflectorless safety, data management, collimation, and COGO, you elevate your surveying from guesswork to guaranteed precision.

Remember: A total station is only as smart as its operator. The TCR805 is a classic, robust machine, but it demands respect for its procedures. Keep a printed copy of the quick-reference card in your vest pocket. Practice the two-face test every morning. And when an error code appears, resist the urge to guess—open the manual.

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.

Leica TCR805 Total Station — Quick User Manual & Practical Work Tips

Part 1: Understanding Your Leica TCR805 – A Manual-First Approach

Before pressing a single button, the manual emphasizes a hierarchy of knowledge. The TCR805 is a non-robotic, manual total station with a 5-second angle accuracy (5") and a reflectorless EDM range of up to 80 meters (to a white surface) and 150 meters with a prism.

Why "User Manual Work" Matters for the Leica TCR805

The TCR805 is not a "point-and-shoot" device. It is a sophisticated piece of optical-electronic engineering. The official user manual spans hundreds of pages, covering everything from basic leveling to advanced coordinate geometry (COGO) routines. Skipping the manual work leads to common errors: misinterpreting EDM errors, losing data during transfer, or damaging the vertical axis.

User manual work refers to the disciplined process of:

  1. Reading and understanding the operational sequences.
  2. Practicing the button sequences (soft keys, hot keys).
  3. Troubleshooting errors using the manual’s reference tables.
  4. Applying the correct formulas for atmospheric corrections.
  5. Performing routine checks (calibration and collimation).

Ignoring these steps results in wasted time on site and unreliable data. Let’s dive into the core components of the TCR805 that every user must master.
