Calibration Points
Select the number of points to take during a calibration. The minimum recommended
number of points for an initial magnetic calibration is 12, although a Hard-Iron-Only
(re)Calibration can be performed with only 6 recommended samples. The TCM will
need to be rotated through at least 180° in the horizontal plane with a minimum of at
least 1 positive and 1 negative Pitch and at least 1 positive and 1 negative Roll as part
of the 12 points.
Calibration Method Buttons
Full Range Calibration - recommended calibration method when >45° of tilt is
possible. The minimum recommended number of calibration points is 12.
HI Only Calibration - serves as a hard iron recalibration to a prior calibration. If the
hard iron distortion around the module has changed, this calibration can bring the
module back into specification. The minimum recommended number of calibration
points is 6.
Limited Tilt Range Calibration - recommended calibration method when >5° of tilt
calibration is available, but tilt is restricted to <45°. (i.e. Full-Range Calibration is
not possible.) The minimum recommended number of calibration points is 12.
2D Calibration - Recommended when the available tilt range is limited to ≤5
°. The
minimum recommended number of calibration points is 12.
Accel Only Calibration – Select this when only an accelerometer calibration will be
performed. The minimum recommended number of calibration points is 18.
Accel Calibration with Mag – The user should select this when magnetometer and
accelerometer calibration will be performed simultaneously. The minimum
recommended number of calibration points is 18.
