'''Notes'''
 * We have to reboot standalone everyday.
 * I changed thresholds of WATCHDOG 800 for LVDT and 80000 for Geophone, because WATCHDOG always tripped during TF measurements due to the resonant peaks.

Activities

  • Set a calibration factor of each LVDTs.

Sensor

Efficiency [um/cnt]

LVDT H1

0.154

LVDT H2

0.146

LVDT H3

0.150

  • I measured TF in L, T and Y.
  • The results were saved at users/tanioka/TMS/TF/20180718.
  • The measurements were done by swept sine and the excitation amplitude was 3000.
