Hi,
  When I tried to archive the vacuum data with
ChannelArchiver, I got some data like:

03/09/2004 15:58:23.254187014   0.000
03/09/2004 15:58:43.254186214   0.000
03/09/2004 15:59:00.000000000   0.000
03/09/2004 15:59:03.254185414   0.000
03/09/2004 15:59:20.000000000   0.000
03/09/2004 15:59:40.000000000   0.000
03/09/2004 16:00:00.000000000   0.000
03/09/2004 16:00:20.000000000   0.000
03/09/2004 16:00:40.000000000   0.000
03/09/2004 16:00:43.254181414   0.000
...

  I have retrievaled it with CGIExport or ArchiveExport many times, but
the results were disappointing.
  So, Why can't I get the same proper value(e.g. 1.324e-07) as using
"caget" instead of zero?
  Furthermore, why the time interval is not the value i set in the .cfg
file(20 seconds)?
  Is there something wrong with the configuration of the ArchiveEngine
or the retrieval tools?
  How can I get the data I want? 
  Help me, thanks!

Best Regards,
