Hi all, I placed a resistance parallel with the coil, but the damping = does not seem to occur. The problem is, the pendulum keeps swinging = (sometimes even visibly!) and for now it did not had any plans to = cease its motion. My coil has a resistance of ~500 Ohm and I am using a 1000 Ohm resistor. A 'diagram' would look like the following: )------R--------> to the amplifier ) R ) R )------R--------> to the amplifier )=3Dcoil R=3Dresistance ----=3Dwiring To show the output of the instrument, I have connected it to an old PC via an old amplifier and 8 bit A/D card (I will have Larry's card in the near future), but the motions of the pendulum keep = saturating the A/D card. Any input? Thanks in advance. Best regards, Marchal van Lare _____________________________________________________________________ Public Seismic Network Mailing List (PSN-L)
