3.6.4 Text Format Data File Examples – Figs. 3.5 to 3.8
Text format archived data is stored in a comma separated value
(*.csv) format so that it can be imported directly into a standard
spreadsheet, e.g. Microsoft Excel™ and Lotus 1-2-3™. The
files can also be read as an ASCII text file by a text viewer. When
imported into a spreadsheet, the files appear as shown in Figs.
3.5 to 3.8.
Alternatively, detailed graphical analysis of the data can be
carried out on a PC using the Company's DataManager data
analysis software package.
3.6.5 Text Format Data File Digital Signatures – Fig. 3.5
A digital signature file is created for each channel data file using
the same filename but with a *.S** extension. The file contains a
unique 'fingerprint' of the contents of the data file that can be
used to prove if the data has been tampered with or corrupted.
Data validation can be carried out on a PC using the Company's
DataManager software package.
