Hi all

I got new hardware from larry today and I was setting it up. I have
problems setting up the gain for Channel 1 (Z). I don't get it up as hig
as I want. This can be seen on my online plot now, when a earthquake
appears on E-W and N-S, it doesn't appear on Z.

I might be wrong on this, but I don't think that the gain is as hig as I
want it to be. But I won't really know until I get a desent size
earthquake to mesure it with. But I did recored a mag 2.8 (IMO automatic
system tells the that was it's size) and I did see it on all channels,
uncluding Z, but Z only had 110nm top, but n-s had 290nm top and e-w had
410nm top. I want to put the gain settings for all the channels on the
same level. I don't think that is the case at the moment.
