Hi Meredith,  I have seen a similar test, using a small folded piece of =
paper on a thread.  The thread was pulled which removed the small piece =
of paper from the pendulum arm.
This was one of the AS1 wed sites, I think.

  Hi all,

  Quite some time back, their was a reference (text) regarding a rough =
"deflection" test;=20
  where a small item (feather or something similar), was placed upon the =
mass of a
  vertical seismometer, and that displacement was a rough measure of (I =

  Anybody have a knowledge of such; or a exact PSN email reference...or =
their
  experiences?

  Thanks, Meredith Lamb
