Dennis,
I think you should be able to run with a gain of 20 or so. The trace
should always show some vibration.

I just recently received and as1 and was wondering what is the
optimal gain for the helicorder to where you get earthquakes but not
as much kid noise. I have mine set to 1 currently but is that
sensitive enough to pick up events?

Hi All,Dennis Griner
I am having trouble with my computer clock. Every morning when I
come in I ping "atomic clock sync" and my clock is off by about 3.5
minutes. I have the program set to ping automatically but that only
happens once a day. Is there a way to automatically ping more
often? Why is my clock so inacurrate?

Hi Dennis,
I have had my AS-1 on a counter in a 2nd floor classroom (gain = 25), under
my desk (gain = 30), on the floor at the side of the classroom next to the
wall (gain = 40), and currently in the corner behind a display case (gain =
80). Use whatever it takes so that the background noise is 1-2mm.
