7. As a final adjustment, use an inclinometer to measure the angle. Place the
inclinometer as depicted in the photo below. Adjust the eye bolt so that the inclinometer
reading is 90 – Mount Latitude_Angle degrees with respect to horizontal.
Example 50.3 degrees.
Figure 18 – Placement of Inclinometer for Adjustment of Latitude Angle
Example:
Mount Latitude Angle = 39.7 degrees
90 degrees - Mount Latitude Angle
90 degrees - 39.7 degrees= 50.3 degrees (Mount Latitude with respect to horizontal as seen
with an inclinometer)
