[Fig. IV-2-21] Display-FFT in VLM
[Fig. IV-2-22] Display-Octave in VLM
But octave and FFT graph is shown only in the WBCombined Filter. The 1/1, 1/3 and 1/6 Octave
analysis which is selected in FFT option window is supported. So after you changed to FFT mode,
you have to press the FFT option button
to set octave. If you want to see the detailed contents, see
the chapter V-5.
The FFT and Octave Graph of the Vibration Level Meter are supported in the
Human Vibration Filter, BW 1.6kHz, BW 200Hz and BW 100Hz. They are not
supported in another Filter. Also, the option of octave is set in the FFT option
window.
3. Display Option
3. 1 Trace Graph
If you press the
button, the display option window appears as [Fig. IV-3-1]. The option in the
red square is only for vibration level meter. The range of y-axis in the trace graph is defined at
[Range] as [Fig. IV-3-1] or you can input this range with keyboard. If user clicks the Y-Axis by
stylus pen, the range of Y-Axis is automatically adjusted.
