Operating conditions
The recommended operating temperature of the motion trackers is between -10°C
and +50°C. If operated outside this temperature range performance may decrease
or the motion trackers might be damaged. Fast transient temperature fluctuations
may cause significant temperature gradients across the device.
The motion trackers contain the absolute possible minimum amount of
ferromagnetic materials. Nonetheless, some minor components can be magnetized
permanently by exposure to strong magnetic fields. This will render the calibration
of the magnetometers useless. Therefore, it is necessary to prevent exposure of
the motion trackers to strong magnetic fields, such as close proximity of
permanent magnets, speakers, electro motors, among others. It is also advisable
to ensure that measurements, in particular calibration steps, are conducted in an
area free of or with minimal magnetic distortions.
The motion trackers should be protected from electro static discharges or sources
of radiation, as exposure to such sources will damage the internal electronics. The
motion trackers should be protected from violent handling such as drops on hard
surfaces. Excessive shocks or violent handling may damage the motion trackers.
The motion trackers, cables and must be kept dry at all times. Condensation and
water may damage the internal electronics.
The motion tracker is intended to be used on clothes.
