keyword=reference cell system fix
16:53 Access to the hall reveals that the hydrogen part of the control box for the reference cell is not working. The hydrogen was switched to the nitrogen plumbing and the nitrogen is disconnected. 3He should still be working fine but the gas bottle still needs to be opened prior to use.
The first step in repair will involve disconnecting the control box and removing it from the rack to allow the problem to be diagnosed. Scot Spiegel is the expert and estimates several hours to get the box opened, diagnosed and re-installed.
