- Set a calibration factor of each LVDTs.
- 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.
- I changed thresholds of WATCHDOG 800 for LVDT and 80000 for Geophone.

Geophoneの伝達関数が高周波でフラットになっている。 本来は周波数の1次で落ちていくはず。
