After remounting the T240 on the BRSY table with through bolts, rather than just sitting on the table with pointed feet, we 'centered' the masses--this was Wednesday afternoon.  This morning I checked again and the mass centering positions were all  about 1 volt.  Not terrible but above action level had these been on an ISI mounted T240.  So I centered it again this morning.  A couple minutes after expressing the 5v required to initiate centering, the readings were at 1 to 7 percent of 1 volt.
