Your Colibri GUI should look like this:
Use "Tools">" Multiorientation" to test the tracker.
Magnetometer calibration
The Colibri sensors are factory calibrated and tested before being shipped. However, the magnetic
calibration is very sensitive to environmental changes. Especially metal and electromagnetic fields
emitted by other devices can influence the quality of the tracking results. To obtain the best
possible orientation estimates, the Colibri should have its magnetometers recalibrated once it has
been mounted in the way it is intended to be used. Not doing so will result in degraded orientation
estimates.
