Jim & I shifted the instrument back to the 40m hole.  It was not reading centered still when we left it at 1030PST but when I went back at 1200 all legs were reading under 1V.  There was one leg at 0.9 so I centered the masses again but it was still at 0.9V ten or so minutes later.  I may need to tweek the level to change this but action level is +-1.5 or 2V depending on manual source.  So, I deem the seismo ready to use and that time starts at 2100 utc 26 Feb.
