Leica Tcr805 Total Station User Manual Work Upd Access

Rotate to the second control point, input its details, sight it, and press + REC .

: This powerful onboard program allows you to set up the instrument over an unknown point. You measure distances and angles to at least two known points, and the instrument automatically computes your station's coordinates and orientation.

Adjust the tripod leg heights to center the circular bubble vial.

Enter the target bearing/Hz-angle into the screen (e.g., 0.0000 for North) and press . The horizontal circle is now locked to that orientation.

Aim the telescope crosshairs perfectly at the center of the backsight prism. leica tcr805 total station user manual work

Once the circular bubble is centered, the instrument is coarsely level, and the laser plummet should still be hovering very close to your ground point.

[Step 1: Position Tripod] ➔ [Step 2: Coarse Level (Legs)] ➔ [Step 3: Fine Level (Tribrach)] Step 1: Centering over the Ground Mark

Target your second known control point, enter its ID, and repeat the measurement. Rotate to the second control point, input its

Rotate the total station until dHz = 0° 00' 00" . Lock the horizontal motion screw. Direct your prism bearer onto this line of sight. Look through the telescope and sight the prism. Press . Read the screen feedback: Length Correction ( ): Tells the prism bearer to move closer to ( ) or farther from ( ) the instrument.

Internal memory capable of storing up to 10,000 fixpoints or measurements. Step 1: Tripod Setup and Instrument Levelling

To establish a coordinate system, the total station must know its own position (Station) and the direction it is facing (Orientation). Step 1: Input Station Coordinates Go to MENU > . Select Set Station (F1). Enter the Station Point ID, instrument height (

Re-level using the electronic bubble; check tripod stability. Heavy fog, dust, or prism misalignment. Adjust the tripod leg heights to center the

Input the known coordinates of your current point: Northing (Y), Easting (X), and Elevation (Z). If you are using an arbitrary local system, you can use 1000.000, 1000.000, 100.000 .

Carefully take the TCR805 out of its hard case, place it onto the tripod head, and secure it firmly using the central fixing screw.

If the TCR805 fails the calibration check, it may require adjustment by a certified Leica service center.

Utilize the built-in electronic level for maximum accuracy, accessible via the display menu, rather than relying solely on the circular bubble. 2.2 Leveling Procedure Center the tripod roughly over the point.
