We located 4 accelerometers and 2 shakers for the PR3 chamber.
I checked these ACCs' signals. The ACC on the leg ("BNC1" channel) is quite smaller than others.
It looks like it is not working, but it also responded when I jumped nearby.

Yokozawa-san turned off the FFU on the pre-booth of the PR3 at 15:02 today.
I compared the accelerometers' ASDs before and after this work. There are no significant changes.
