: Before first use, fully charge the batteries using the official Leica charger. The TCR805 offers flexible battery options; using a high-capacity battery (such as the GEB121) can support an entire day of work, powering approximately 4,000 standard measurements. Step 3: Fine Levelling via the Electronic Dual-Axis
Use this method when your instrument sits directly over a known control point. Select > Station Setup > Set Orientation . Enter the coordinates of your current station point ( ) and the instrument height (
Measures the distance and displays the coordinates on screen without saving. REC: Saves the current data directly to the memory.
Press . The instrument will measure the distance, compute the Easting ( ), Northing ( ), and Elevation ( ), and immediately save the data point to memory. Stakeout (Setting Out Points) Go to Programs > Stakeout . There are no clamps
The Leica TCR805 User Manual provides detailed steps for instrument setup and basic functions:
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.
