Sensor Control Commands
The main reasons for compass calibration are installation of the instrument into a new mount or boat or
moving to a new location for data collection. Each new mount or boat potentially carries a different mag-
netic signature, and the earth’s magnetic field characteristics vary from location to location even over rela-
tively short distances. The compass calibration algorithm corrects for the distortions caused by these ex-
ternal field changes to give an accurate measurement.

Compass Command Descriptions
SA – Compass Cal
Purpose Calibrates the compass to remove hard and soft iron effects.
Format SAx
Range x = 0 to 4 (0 = help)
Default N/A
Recommended Setting. Use WinRiver II to calibrate the compass. The compass must be calibrated if
the boat and/or mounting have changed or the RiverPro/RioPro is moved to a new location.
Description Command used to display compass module information, enter calibration mode, and set
compass module parameters.
For details on how to calibrate the compass, see the WinRiver II User’s Guide.
