Please see S-T Morrissey response. I didn't even know it had a period
adjustment until your message! After reading your email message I took a
closer look at the sensor. I took it offline to but it on the bench and I
swear to god no more then 2 minutes later we had a Ml 2.8 event near by.
Talk about Murphy's law....This would have been a nice event to record with
my new sensor (*.lc9 files)...

Dave Nelson, should I update Arie's station information or can you do it?
