The following demonstration procedure familiarizes you with the Main and Configuration screens and the
calibration functionality.

1. Launch the sensor toolbox software by using the procedure in
2. Rotate the device in a figure-eight motion as advised.

The main eCompass screen appears with a red magnet warning icon in the Calibration frame,
indicating that the compass is out of calibration. Text at the bottom of the frame advises Rotate in
figure of 8 to measure geomagnetic field.
When a minimum of 16 magnetic measurements are stored in the Smart FIFO, the compass
software uses those measurements to calibrate the device. The default, 10-element calibration is
composed of:
— Three elements in the Hard Iron frame
— Six elements in the Inverse Soft Iron Matrix frame (There are not nine elements because the
