Hi Aaron,

   I was wondering if a delay between the readout of each sensor (eg. ~0.5
second) may also help. I don't understand the origin of the problem, so I'm
just guessing. Or we could try one thing at a time to better understand the
effect.

Maybe there is something related to the way these variables are then dumped
into the EPICS system. Are these put one by one in EPICS as they are
scanned, or 'at once' at the end of each cycle?

Thanks,
Carlos
