Hi,

I finally have my instrument up and running again to an extent.  I have =
converted to the Dataq 154RS and Amaseis.  I have some questions on =
Amaseis and my results.  First is I expected and set a zero level of =
2048 from the 12 bits.  On my display the data value shows as 30800 =
approximately.  In Windaq the trace runs very close to zero voltage and =
is not offset significantly.  Next, on the helicorder display I get =
large spikes and about 2 minutes of missing data on each hour.  If I =
extract an event across the hour the event does not show the spikes.  It =
seems to be only the helicorder view.  A screen shot can be seen at =

content on the page. =20
