Hi Jessica,

I have seen this before (although not with the same pattern you're reporting)
and I don't think it has anything to do with the actual nitrogen level. My
recollection is that this was due to a transient interruption in communication
between the sensor and BSMS. Assuming you have already updated your BSMS to
the latest firmware for all components, I would reseat the cables connecting
the nitrogen sensor to the ELCB and then reboot the latter. If this is on an
instrument with a BSNL I would also check the logs on the CCU to see if anything
strange seems to be happening there; that should narrow down whether the issue
is with the sensor or BSMS.
