LI-COR LI-710 - Terrain, Slope, and Tilt

Section 2. Deploying the LI-710
Terrain, slope, and tilt
You can expect good results as long as the sensor is within a few degrees of per-
pendicular to the slope of the area-of-interest. The grade can range from 0 to 10%.
Measurements from the sensor are not highly sensitive slopes up to 10° from level.
The level application on many mobile phones is adequate to confirm that the tilt of
the sensor matches the grade. Tilt from vertical is recorded in data group 2 (see
Group 2: Air, humidity, and instrument information on page7-3).
Figure 2-8. On sloped terrain, install the LI-710 perpendicular to the predominant slope of
the area-of-interest. A few degrees of difference is acceptable.
Figure 2-9. On level ground, install the LI-710 with 0° tilt, although a few degrees of dif-
ference is acceptable.
