17:30 or so... noted in preflight that 180/400 MED setpoints wouldn't work at sea level. Changed to 170/450, but PBy looked low, so sticking with 130/580 for this flight... 18:15 noted that flows are low, around 96/97 sccm for AO2. This appears to be because we are now at sea level to start? Miscommunication meant that these were not adjusted up before flight. AO2 LAG WILL BE GREATER FOR RF02. 18:43 changed to auto control of AO2 cals. O2 spikes briefly at this point. 19:28:20-19:29:30 AO2 inlet breath test, saved 110616_AO2_breathtest1_2820_2930.png 20:04 fantastic sudden change in O2 and NOT CO2 over open water. Change on order of 30 per meg increase. 22:11 Forced cal to get full profile at northernmost point. 22:11 Reset calint to 50 after purges started 22:52:19 Changed to 90/690 MED P setpoints 23:00 Forced AO2 cal in anticipation of ACTUAL northernmost point previous was miscommunication. 23:18 But realized that forgot to reset to 50. Reset to 50 This means AO2 got two cals almost back to back. 21:00 MEDUSA continuing to make more noise than previously. Concern that the pump may have a diaphragm problem or an even more serious internal problem. 00:53 Cal started, and we started ascending to 41kft. Set to manual control, deselected purges. Will reset to auto after we reach 41kft and have 5 mins flow 01:07 Restarted Cal just after reaching, and then almost immediately descending from 41Kft
