- 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.

Measured TFs when we excite in Y direction. 
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。
Geophoneの共振ピーク付近でディップ（？）のようなものがみられる。
