Hello,
I have just built and setup a Lehman design seismometer. I built it for =
my school science fair, so keep in mind when replying that I am not in =
tune to all of the technical stuff. My questions have to do with =
adjusting the seismometer to record correctly.
Attached is a sample of the data that I am currently getting. I was =
wondering if I need to damp more or if I need to turn down the gain or =
adjust the offset. I am using Larry Cochrane's Amp/Filter board and his =
16 bit A/D converter board. I have also read about changing the period =
length, but I am not sure how to change it. Any help getting this data =
to look right would be appreciated.=20
thank you,
