Instrument Problems:

1. The acquisition system is still enduring many periods of cyclic reboot while running with no problems during other long periods.
2. POLDER shutdown at 18:26 and didn't restart.
3. System has been modified to allow reset of POLDER haed and reboot in case of system hang-up. This worked for a while but the system finally shutdown improperly and never came up again. At this point, Scaled doesn't recognize any problem in their electrical configuration. POLDER team will pursue investigations on potential instrument failures.
