Depending  on  your  instrument  model  the  following  integration  methods  are 
available: - 
 

Method 

Description 

Acceleration 

A vector quantity which is the rate of change of velocity with 
respect to time.  Displayed in g on the GA2002 and in m/s

2

 

(metres per second per second) on the GA2003.   (g is the 
acceleration  due  to  gravity  on  the  earth’s  surface  and 
defined as 9.80665 m/s

-2 

 

Velocity 

The speed at which an object travels in a particular direction.  
Displayed in mms

-1  

(millimetres per second

) .

 

 

Displacement 

A measure of the movement incurred on an object from a 
resting position.   Displayed in µm (micro metres). 

 

 

 
Performing a mathematical integration function on Acceleration gives Velocity 
whilst integrating Velocity gives Displacement.
