Don’t know about Callisto, but a friend of mine with the previous software had a similar problem.
If he re-started the computer each day the problems were significantly reduced – like one of the buffers was only being cleared out on re-booting.
He then started to turn the source off then back on again each day and reckoned the problem went away completely. I could never work out why this should make a difference but he swore blind it did. The jury is still out on that one …
At the time I spent a significant amount of time examining his traces / data and could see no evidence of flashover – in fact it usually stopped during the CO2 analysis part of the run where the source was at 2500V, flashover usually occurs during the N cycle when the source is at 4500V.
Probably worth asking Andy / Wayne at Sercon if they can have a look at the software for you or tell you which buffers to check.

We have a Callisto software-powered 20/20 irms with electronics update and the software has taken to crashing, giving the error message:
EA N and C batch:
Plot buffered Data Graph:
Error Subscript Out Of Range
Select signal: a=1 b=1 c=1
Initial advice from Sercon was that flash-overs were occuring in the source to cause this. These stoppages continue to occur however after two re-builds of the source. We have taken to restarting the computer on a daily basis, which may have lowered the incidence – or may be a lucky streak.
Has anyone seen this before? (the stoppages, that is, not the lucky streaks)
Thanks very much
