Hi all,
 
Quite some time back, their was a reference (text) regarding a rough "deflection" test; 
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 think) of its
crude sensitivity?
 
Anybody have a knowledge of such; or a exact PSN email reference...or their
experiences?
 
Thanks, Meredith Lamb
