[Dsg-rich] RICH status

[Tyler Lemon]

Hi Marco, 

The Forward Carriage is being moved today, so we are unable to get access to the compressor for the tests and to power it down. 

We will perform the tests tomorrow. 

Best regards, 
Tyler

Hi Tyler, 
tests are welcome but please keep attention to the 
humidity level inside the RICH. The compressor flow 
leakage brings humidity, in particular when not warmed 
up by the electronics (with LV off). 
Thanks, Marco.
