Since Hall B is in restricted access, we checked RICH humidity sensors #6 and #14. The interlock override switch was used to prevent HV/LV from being disabled during the debugging.

While debugging, all humidity sensors were disconnected from the cRIO to check the screw terminals on the module connector. This is why there were a few periods where all humidity sensors dropped to zero.

The wiring in the cRIO chassis appeared to be fine. The power and ground leads of each sensor were secure in the terminal block and module screw terminals. The +5V power supply was also verified to make sure it is providing a constant +5V to power the humidity sensor.

Since nothing was found wrong in the cRIO chassis, the next steps would be to check the feed through connectors at the RICH. Since this will require a lift, this task could be done over the summer shutdown.

The override switch for the interlock system has been disabled. The cRIO is now back running as normal.
