9 Preparing for a MOTION recording
9.1
Mounting
The Actiwave MOTION may be mounted in any required
position on the subject. The quick release belts /
mountings are available in several sizes to allow
comfortable fitment to the waist, torso, upper arm, thigh or
ankle. Adjust the length of the mounting strap to keep the
device from moving but without causing discomfort for the
subject.
9.2
Orientation
The figure below shows the orientation of the three axes
relative to the case markings.

Sampling
The sampling rate is very dependent upon the application.

more limited recording time. The table below shows the
