      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
