Accelerometer Types, Removal and Fitting
Accelerometer types for use with the Excieo produce a Voltage Output
proportional to the signal being measured.
Below is a table which shows the output voltages and specifications of the Hand
Arm Tri-Axial Accelerometer (KD1006), the Whole Body Tri-Axial Accelerometer
(KD1007 & KD1009) and the Single Axis Accelerometer (KD1003): -

Where g is the acceleration due to gravity on the Earth’s surface and is defined
as 9.80665 ms

.
Acceleration is defined as the rate at which an object changes it velocity.
Velocity is measured in metres per second (m/s) and therefore acceleration is
measured in metres per second per second (m/s/s) which can be written as
either of the following: -
