(11) The tendency management of the
acceleration, speed and displacement of the
vibration can be performed by using the OA
Trend.

(12) FFT cf. displays FFT spectrums of the past 3
times with overlapping them.

(13) Both of FFT spectrum and time waveform,
after tapping cursors 1 and 2 at the bottom of
the graph, swiping them on the graph moves
the cross cursor, and by releasing the finger,
the position is established. The displayed
cursor coordinates are the coordinates of the
cross intersection of cursors 1 and 2 and the
difference. The waveform graph can be
expanded or reduced by pinch-out or pinch-
in. Moreover, by swiping in horizontal
direction, the scroll in horizontal axis can be
performed.
