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
Turn Screws A and B simultaneously in opposite directions (both in or both out) until the electronic X-axis sensor reads 0° 00' 00" (or within a few seconds). leica tcr805 total station user manual work
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.
