For the webopi version

  1.  go to RICH Overview from the main menu
  2.  then click on the Hard Interlocks button in the upper right and select Interlock Controls
  3.  click on the Details button near the middle of the screen in the N2 Volume and Gas section
  4.  finally click on the N2 Volume Sensor Locations

Here's a direct link to that screen once you've already logged in to the webopi page if you don't want to go through those steps.

https://hallbopi.jlab.org/webopi3.3/w?opi=https://hallbopi.jlab.org/opis/apps/cRioIntlkApp/RICH_S1_N2.opi

When I go to that page I get non-zero values for the humidity sensors, like in the attached image.

Hello,
thank you everyone for this work.
But I have one question now, how can I check the status of the N2
system? From the web OPI interface it looks that all the humidity values
are at 0.
