 Description   

Hi Craig,

We have strange behaviour here with pressure gauge of R0 (CRA-R2).
It was working well, then during the night there was a jump in pressure.
Not much to test while under vacuum so we decided with Rudy to unplugged it but it was still returning a value (the exact same value 9.751e-5), then we plugged it back or pressure change but after a while it reached the same pressure.
