Hi Bob,
this jumping of the Volt-signal is something we also had here and there,
however, not any more since a year or so. It also only appereared in the
morning (after an overnight sequence) when we wanted to check linearity etc.
before the next run of samples. We never tried to follow the reasons for
that because it was always possible to "fix" it by just rebooting the
computer. I assume it is an electronic problem, however, would not like to
buy a new board.
Hopefully, your problem is the same we had.
Cheers
Maren
P.S finnigan had no clue of what the reason could be..
