To determine if the mounting locations magnetic field is within the dynamic range of the compass, the
following test should be performed:
With the compass mounted, rotate and tilt the systems in as many positions as possible. While doing so,
monitor the magnetometer outputs, observing if the maximum dynamic range is exceeded. It is
preferable to have some margin before hitting the dynamic range limit of the module.
3.3 Mechanically Mounting the TCM
Refer to the TCM Dimensional Specification later in this manual for the TCM board dimensions and the
orientation of the reference frame.
The TCM is factory calibrated with respect to the mounting holes, as shown below, thus it must be aligned
within the host system with respect to these mounting holes, not the board edges.
