[Dsg-htcc] HTCC O2 Concentration

[Jennifer Williams]

Yes, please use the oxygen monitoring to measure at the exhaust.
Before you open the HTCC please contact me, I will bring another meter 
to provide a second check of oxygen levels.

We don’t currently have an estimated time for the O2 concentration to reach a safe level as of this moment, but as soon as we know anything we will let you know. Also, we currently only have one way to measure the O2 concentration, the safety monitor, so we will attempt to use this to measure the concentration at the exhaust unless you advise otherwise.
