[Dsg-rich] [EXTERNAL] Re: [New Logentry] RICH compressor ON after maintenance

[Marco Mirazita]

Hi Tyler,
I completed this first test on the RICH (elog 
https://logbooks.jlab.org/entry/3733786) and the detector is now off.
I would ask you to turn the compressor also off, unless you need to make 
some further test.
The compressor on and electronics off is a condition we want to avoid, 
because it generates an increase of the humidity inside the RICH.
Thank you,
Marco
