Figure 16. RiverPro/RioPro Compass Calibration Screen – Pitch/Roll
The Pitch/Roll calibration requires eight rotations while pitching the RiverPro/RioPro up and down.
• For the bottom row of squares, pitch the RiverPro/RioPro between -22.5 to -45 degrees.
• For the second row, pitch the RiverPro/RioPro between -22.5 to 0 degrees.
• For the third row, pitch the RiverPro/RioPro between 0 to 22.5 degrees.
• For the top row, pitch the RiverPro/RioPro between 22.5 to 45 degrees.
Each row can be completed during one rotation or you can vary the pitch as you rotate. A
good compass calibration requires slow, smooth movement to allow the compass to collect
data at each point.
