CHAPTER 3 Operating Procedures
3 - 39
(e) Number (of data)
You can specify the number of FFT computation points for mechanical system
diagnostics. The larger the number of points, the higher the measurement
accuracy. However, the time required for a data upload will increase with an
increase in the number of points. You can use a relatively low setting for
making initial rough measurements and raise the setting for final detailed
measurements to reduce the required measurement time. In principle,
measurements should be at a maximum setting of 4096 points.
(f) Window (function)
A window function can be exercised for the data. If a measured waveform is
messy, it may become clean when you change the window function option.
You should basically use the "Hunning" setting for measurement purposes.
(g) Operation (range adjustment)
When you decrease the setting, the operation range for measurement
decreases, but the waveform of a low-frequency region becomes messy. If the
waveform of a low-frequency region is disordered at a default setting, you
should increase the setting.
