Array format
The values are stored as follows within the array (all
values 4 Byte):
Designation Content Meaning
version 000 Version of the data
structure
ms 1 Interval between two mea-
surements in ms
vi1 i Value, recorded at point 1
(Index)
vi2 i Value, recorded at point 2
(Index)
vi3 i Value, recorded at point 3
(Index)
number nn Specifies how many mea-
surements follow
data ... Measurement data
... ... (total nn*3)
number 0-mm Number of measurements
(if others are present)
data ... (see above)
NB!
Please make sure that the size of the array
is sufficient for the recording. You need 6
elements for the header, 1 element for the number,
and 3 elements for each measurement. Thus for
100 measurements you need 307 elements.

available for this.
