Note 2: A mobile phone often has a loudspeaker which contains magnets itself.
For best performances of your system, you must respect conditions of use and rightfully choose the
site where you carry out measurements:
-
You must carry out sessions of measures at a usual chosen place, where magnetic
disturbances are minimal.
-
When various postures or positions are carried out by the subject, it is necessary to avoid
translations higher than 1m of amplitude. The static magnetic field must be constant and
uniform inside the area of work.
-
Keep any ferrous objects far from measurement site (approximately at a distance twice the
largest dimension of the ferrous object) ; for example :
o
Scissors : 30 cm
o
Laptop battery : 50 cm
o
Keys : 15 cm
o
While using the MOTIONPOD™ for measurement or calibration (see further below),
see to it that there isn’t any object likely to disturb measurements (ferrous objects,
watches, mobile phone…)
o
MOTIONPOD™ should be used far from motorized chairs or beds.
o
Only small magnets are accepted in the same room (i.e. whiteboard magnet), but
must be kept far from the MOTIONPOD™ (>50 cm), as they might cause a serious
decrease in the systems accuracy.
o
DO NOT TO PUT THE MOTIONPOD™ IN CONTACT WITH A MAGNET AS IT WILL
MAKE IT PERMANANTLY USELESS.
o
The presence of strong magnetic field generating machines (like MRI) is not adapted
to the use of MOTIONPOD™.
