To acquire data and export it, follow the procedure below:
Select the parameters you wish to log in the window on the left. Use Shift -Click and
Ctrl-Click to select multiple items. In the screen shot above, “Heading”, “Pitch”,
“Roll”, and “Heading Status” were selected. Note that Heading Status can be 0, 1, or
2, corresponding to “green”, “yellow”, or “red”.
Click the button to start logging. The button changes to a
button after data logging begins.
Click the button to stop logging data.
Click the button to save the data to a file.
Click the button to clear the data from the window.
Note that the “Distortion” log indicates if the magnetic field is > ±125 µT for any of the
magnetic sensors. It is only applicable in Compass Mode, and will always read “FALSE” in
AHRS Mode.
6.8 Graph Tab
The Graph Tab provides a plot of the measured field strength on the x-axis and y-axis
magnetic sensors.
The “Filt” data and plot (blue) provides magnetic field strength measurements after the FIR
filter taps are applied, but prior to applying the user calibration coefficients. The “User” data
and plot (red) provides data after applying the user calibration coefficients. In AHRS Mode
the data and plots are identical, while in Compass Mode there is an offset which represents
