Assembly works

  • By Akutsu

Geophone pod assy

  • One pod was badly manufacutured, but anyway I succeeded to assemble a horizontal geophone.
  • See here.

  • Named GeoH1 (L-4C #15, the driver sn#164)

LVDT setup

  • Just connected all the relevant systems including one of the LVDT itself (today it was No.6 to LVDT-V1).
  • Adding an AC bias, the signal was somehow observed from the digital system... but I need more persons to tune the gain and the demodulation phase to do the calibration...
