Introduction
1. The Official Source (Leica myWorld) The safest and most reliable place to get the PDF is the official Leica Geosystems website. You will want to search for the "User Manual for TPS1200 Series". Note that Leica often groups the TCR, TCA, and TC versions into one comprehensive manual. Total Station Leica Tcr 1203 Manual
Once leveled, the instrument must be "told" where it is in space. Through the Manage menu, the user inputs the coordinates of the occupied point. The next step is the "Backsight" — sighting a second known point to establish the horizontal orientation (Azimuth). The TCR 1203 software calculates the error between the measured and theoretical distance, allowing the surveyor to verify the setup before proceeding. 3. Measurement Modes The TCR 1203 offers various measurement programs: Surveying: For standard point collection. Introduction 1
The manual’s first critical section covers startup. If you skip these steps, your data may be corrupted. In the Manual: Look for the section titled "EDM Settings"
Reflectorless Measuring: Using Leica’s PinPoint technology, the TCR series can measure to inaccessible objects (like building corners or rock faces) with a small, visible red laser dot. Standard reflectorless range is typically around 400m (R400 model), though some variants reach further.
Based on the manual’s navigation logic (Leica SmartWorx interface via keyboard and function keys F1-F6):
IR Mode: For measuring to a glass prism with a coaxial red laser beam.
