Data taken after we removed scaffoldings in the magnet and replaced Al shield plate with Al foil. Everything is in, with following electrical configuration: S1: Chambers are not tied. Chassis are jumped together. S2: By default, all chambers are tied together. Chassis are jumped. Al shield plates were replaced with Al foil. S3: Chambers are isolated. Chassis are tied within octant but not cross octant. HV: 10K Rs installed. Calib: cable shield wire is tied to chamber, the other end id free.
