In case you cannot perform a digital height reading, you can take an
optical height reading and add it to the levelling line. For more
details, refer to 5.4 Manual Input Screen for Optical Height Reading.

It is recommended to perform a compass calibration before taking an
angle measurement. Refer to 14.6 Calibrating the Digital Compass.
1.
To access the digital compass, select Tools from the main
menu, then Compass.
2. Within the Compass screen, the red arrow of the digital compass
shows the current viewing direction of the instrument. In the output
eld Current Azimuth, the exact angle in reference to north is dis-
played.
The LS15 instrument uses the digital compass to calculate the
coordinates of a measured point. Together with the ofce software
Leica Innity, these coordinates can be used to visualise the position
of a levelling line.
Both the LS10 and LS15 are equipped with a rotatable horizontal circle. The
angle unit is 360° subdivided into 1° intervals. The graduation in gon is printed
in steps of 50 gon below the graduation in degrees.
