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.
Press the following buttons on the specified instrument to operate using the
stated method: -
