Let me ask SERUFUSESUTO of dataseet P31, please.
（１）Are they able to receive more in-depth material about self test?
（２） (1) but when it isn't possible, let me do the following question, please.
１: The time of a self-test mode changes the distance during a pole of each axis by the obctrostatic power,
2: How many G is the acceleration from which I can get ST1 when making Hi,ST2 Low, considerable?
3：When doing Hi/Low control of ST2, does X/Y/all Z axes change at the same time?
4:Is it possible of ST2 to do own dynamic acceleration check including a sine wave?
