10.20 System wide checks ok (except naida07 ADC calibration failure)

FEE temperatures ok (attachment 1)

good event statistics ok (attachment 2)

detector bias and leakage currents ok (attachment 3)

DAQ stopped

10.40 pulser switched off

slow comparator threshold raised to 0x64
      
      DAQ, merger, TapeServer started - all ok (attachments 4 and 5)

good event statistics (attachment 6)

16:11 Tapeserver and merger still ok
      DAQ still running
      System wide checks all ok *except nnaida7 fails ADC calibration*
      Bias and leakage currents ok - attachment 7
      FEE Temperatures ok - attachment 8
      Statistics still ok
      
      Spectrum are showing alpha events (Layout 4) - attachment 9

18:25 Tektronix clock accidentally unplugged. DAQ has stalled as a result.
      Clock reset to 50MHz 5V TTL signal

18:29 System wide check of clock status shows error message in attachment 10

DAQ Reset
      With slow comp at oxa statistics are still good - attachment 11
      System wide checks all ok *except nnaida7 fails ADC calibration*
      Resync to the ASIC clock
      All histograms zeroed

18:37 Slow comp threshold raised to 0x64 for alpha run
