Initially it was found that the 2.5" screws were to long and would not put any compression on the load cell.

For the final tests it we reverted back to the 2" screws, but two of them had a washer to make the screw even shorter.

Attached is a PDF of the notes that were taken as the tests were being done (they're admittedly terse) as well as screen shots from the Mya Archive for the associated timestamps from the notes since attaching a bunch of pictures made this entry pretty busy.

I will note that during the tests when the strip charts were being displayed we saw changes in some of the radial load cells for a few of the tests, but this isn't captured in the archive data. I suspect this is because the dead-band is to small (but only for these tests it's fine for normal operations). I will see if I can recreate the plots with the data that was pulled directly from the cRIO offline.
