Following up on the RICH S4 nitrogen (N2) volume humidity sensor issue from June 1, 2025 (https://logbooks.jlab.org/entry/4388418):

The 5 V power supply for the N2 volume humidity sensors was fine and working as normal.

I swapped the cRIO module reading the humidity sensors for a new one and rebooted system; no effect.

Work on system in the hall is done for today and it is operating as it was before the work. N2 volume humidity sensors are all reading 0.33% and not changing. All other sensors are reading as normal.

The next step will be more remote debugging to be able to find a solution for the next maintenance day.
