Leica Tcr805 Total Station User Manual 【Linux】

Leica TCR805 Total Station is a professional-grade surveying instrument known for its precision, reliability, and versatile measurement capabilities. As part of the TPS800 series, it is widely used in engineering, building, and construction for tasks such as setting out, volume determination, and tacheometry. The following essay details the core components of its user manual, ranging from technical specifications and setup to data management and maintenance. 1. Technical Specifications and Key Features Leica TCR805

is designed for high-accuracy surveying, offering specific features that balance field performance with data integrity:

It provides 5-second angular accuracy and is equipped with a dual-axis compensator to automatically correct leveling inaccuracies. EDM Technology:

The instrument features an Electronic Distance Measurement (EDM) module capable of reflectorless measurement up to 400 meters using a visible red laser beam. Memory and Storage: leica tcr805 total station user manual

It includes internal memory capable of storing between 10,000 to 18,000 points, depending on the specific model and data configuration. Build Quality: The device is rated at

for water and dust protection, ensuring it can operate in diverse environmental conditions. 2. Instrument Setup and Leveling According to the Leica TCR805 Manual (Scribd) , proper setup is the foundation of accurate measurement: Centering and Leveling:

The instrument uses a built-in laser plummet for easy centering over a station point. Users must ensure the tripod is level before fine-tuning with the electronic levels and tribrach foot screws. Station Setup: Leica TCR805 Total Station is a professional-grade surveying

The manual details procedures for "Setting Station," where users enter station coordinates and orientation. A "Free Station" (resection) method is also available to calculate the instrument's position based on measurements to multiple known points. Datum Tech Solutions 3. Operational Procedures and Software Programs

The TCR805 features an alphanumeric keyboard and a large LCD for navigating its on-board software. Key software routines include: Measurement Modes:

Users can switch between "IR" (Infrared) for prisms and "RL" (Reflectorless) modes. On-board Programs: The manual outlines specialized programs for Area Computation Tie Distance (missing line measurement), Reference Lines Rapid Measurement Chapter 5: Resection and Setup Routines The manual

Fast coding facilities allow surveyors to assign attributes to measured points efficiently in the field. 4. Data Management and Transfer

Data collected by the TCR805 can be managed internally or exported for office analysis: TCR805 UserManual 3.0 English | PDF | Ascii - Scribd

Chapter 5: Resection and Setup Routines

The manual dedicates 15 pages to Station Setup and Resection. Unlike modern total stations that automate resection, the TCR805 requires you to manually select whether you are solving for orientation only (with known coordinates) or for both coordinates and orientation (free station). The manual’s step-by-step examples show exactly how many points are needed (min. 2, recommended 3) and how the program calculates residuals.

Key Sections in the Manual You Need to Know

If you are downloading the manual for quick troubleshooting, these are the chapters you will likely reference the most:

Step 1: Centering

  1. Place the tripod over the survey point.
  2. Mount the TCR805 on the tripod head and screw it in loosely (leave it slightly loose for adjustment).
  3. Turn on the instrument.
  4. Look through the Optical/Laser Plummet. Adjust the tripod legs until the crosshair/laser dot is roughly over the ground point.
  5. Use the footscrews on the tribrach to perfectly center the crosshair over the point.
