Precision begins with a stable setup. Follow these steps to ensure your instrument is ready for work:
Saves the current display data to the active job memory.
The TCR805 interface is menu-driven. Without studying the on key mapping, you will get lost. Here is the logic behind the keypad:
Ensure the tripod head is as visually level as possible before mounting the instrument. Mounting and Centering
Once the tilt errors are near zero (less than 5 seconds), press . leica tcr805 total station user manual work
Leica total stations feature an electronic guide and a physical circular bubble to streamline this process.
Open the or Leica Infinity software on your PC.
Set your starting Point ID (e.g., 100 ) and the Reflector Height ( hr = 1.500m ).
Before you see numbers on the LCD screen, you must physically prepare the instrument. The user manual dedicates an entire section to the : Precision begins with a stable setup
Select the job file from the instrument's directory tree via the software interface.
This program calculates the horizontal distance, slope distance, and height difference between two measured points without physically moving the instrument between them——ideal for checking diagonals on a building layout.
MENU → Prog → Survey → Enter ID → HT → Aim → ALL
Load your design points into the instrument memory via data transfer, or manually type in the coordinates of the point you want to find. Select the target Point ID. Without studying the on key mapping, you will get lost
Re-level using the electronic bubble; check tripod stability. Heavy fog, dust, or prism misalignment.
Data is transferred via an using a standard data cable, where the instrument acts as a DTE. The standard protocol for raw data is the Leica GSI (Geo Serial Interface) format, though the TCR805 can also export data in ASCII, DXF, and XML formats .
| Key | Function | |------|-----------| | DIST | Measure distance only | | ALL | Measure + store point | | REC | Store last measure | | EDIT | Change point ID / target height | | PARA | Change EDM, temp, pressure | | PAGE | Next screen (coordinates, angles) |
All field data must be stored within a specific project folder, known as a "Job." Navigate to MENU > > Job . Select New (F1). Input a job name using the alphanumeric keypad. Press Set (F4) to save and set the job as active. 4. Station Setup (Orientation and Backsight)
