vb Data Structure

Instead of analyzing data onsite, you can also record the data on
your instrument and analyze the data later. If many machines need
to be analyzed recommend that recordings be taken of all machines
before any analysis is done. Analysis is best carried out away from
machines in safe, quiet environments.
The instrument uses the following hierarchical data storage structure:
Starting at the bottom of the diagram, a recording is the vibration
data collected at a particular location on a machine.
A parameter set defines a set of measurement parameter values
that can be used to take a recording. These are useful when you are
taking a large number of recordings, each using the same parameter
values.
The direction refers to the orientation of the sensor - horizontal,
vertical etc. Directions are grouped under points as each point can
have recordings taken in several axes.
A point represents a place on a machine that a measurement will be
taken. Points are grouped under the machine that they are located
on.
