WP 12660

Last Tuesday, two 3T Gurulp seismometers in the Biergarten were powered down. A functional/huddle test was performed last November, alog 81097. Power supply and cabling was cleaned up. Before powering down, units were locked via the breakout/controller boxes. Units were left in the LVEA in the PEM area. Units are H1 spares.

Cabling and test equipment for a HS-1 geophone was also removed. This was part of the NN Seismic Array HS-1 testing down last year, alog 81257.
