[dsg-hallb_rich] [EXTERNAL] Re: RICH Humidity sensors

[Marco Mirazita]

Hi Tyler,
in principle it is ok to have zero RH inside the detector.
But with the compressor off the humidity inside the electronic panel 
cannot be zero because that volume is basically open to the outside air. 
I would expect to see values well above few percent, like for the other 
module.
And the fact that the sensors read zero in the electronic panel makes 
suspicious also the zero readout inside the detector.
Could you please check what is going on?
Thank you,
Marco
