    keyword=VDC problem cont.

    Left arm VDC readout missing U1 U2, V1 and part of V2.
    At first I thought it is a gas problem, since the Alarm in the gas shet argon box was making sound. Recall that last shift had to reset VDC voltage. Jack came over and we concluded that
    it could not be a gas problem at all, since right arm VDC is still fine.

    tried reset left FASTBUS SFI, and then AC, doesn't work. Analysis
    code give error: FASTBUS slot 16 extra hit.

    More like a DAQ problem on FASTBUS. Alex was called.
