Hi All, 
            Does anyone have any usefull (easy) advice on setting up the damping on a 
  Mini Lehman.  I`ve read Loads of articles on this subject ,And as far as I can see
  The ideal amount is 0.7 - 0.8 and that means that if I walk up to the seismograph
  and the pen deflects 10mm ,then the pen should return 0.5mm in the opposite direction
  then back to zero. Is it me, or does this seem like too much. I feel i`m going to miss 
  the more distant Quakes, on the other hand ,I dont want the machine swinging wildly
  after every bump. Im just after general advice. Any would be much appreciated!.
   
          Thanks In advance
