Actiwatch Guide to Getting Started 7.2 (July 2009)
Please note that certain models of Actiwatch, although
compatible with series 5 software will only work with a specific
version or later. Specifically this includes the new Actiwatch Mini
and the ActiLight. For full details please contact CamNtech.
Actiwatch activity is measured in counts. This is a term used to
denote the amplitude of the signal produced by the
accelerometer in the Actiwatch. The number of counts is
proportional to the intensity of the movement.
The accelerometer in the watch checks or samples the
amplitude of the movement thirty two times per second and it
captures the highest amplitude in that second.
This represents the peak intensity of the movement in that
second. The peak intensity values are summed into a user
selectable epoch (epoch range between 2 seconds and 15
minutes depending on the model of Actiwatch used). Activity
values can be viewed in counts per epoch in the software or
exported and viewed in Microsoft Excel. Full technical details on
the operation of the Actiwatch can be found in the appendices
of the Actiwatch User Manual.
