• Analysis during some events revealed vibration
  spikes believed to be integration noise generated
  from the double integration process of the
  Velomitor acceleration signal into a displacement
  signal.
• Transducer systems that employ double integration
  of signals are not recommended for this reason
  and it is recommended the station not use the
  absolute (double-integrated) signal for trip
  relay activation.
