About This Product

■For customers just starting to use frequency spectrum-based pass/fail judgments

The CF-4700A FFT Comparator is an ideal line judgment machine for precise quality inspections of product sound and vibration. Equipped with FFT-based frequency analysis technology, which we have cultivated over many years, it extracts characteristic problematic frequency components and performs pass/fail judgments. In addition to the judgment functions of our predecessor, the CF-4500, based on frequency component magnitude and waveform shape, the new model features a fluctuation component extraction function that extracts the amount of fluctuation in periodically fluctuating sound and vibration and makes judgments based on that amount of fluctuation. This function judges based on the amount of periodic fluctuation, rather than the frequency level of the sound or vibration. This function enables pass/fail judgments based on sounds such as muffled "groans" and rattles that occur when motor-driven equipment is operating. Furthermore, the fluctuation component extraction function's bandpass filter and envelope function enable bearing vibration monitoring, and the monitor function (headphone output) enables audible vibration confirmation. A new judgment assist function allows for easy setting of the judgment range. The difference in sound and vibration levels is read from each pass/fail measurement data file and a judgment block is set, so even customers who are trying to make a pass/fail judgment using the frequency spectrum for the first time can easily set up the blocks. Features

■ Four comparator functions determine product pass/fail.

- Block comparator function sets a pass/fail area and determines pass/fail based on the signal level of a characteristic frequency. - Shape comparator function (optional) determines pass/fail based on waveform shape. - Tracking function (optional) changes the rotation speed and determines pass/fail based on level changes of specific orders. - Fluctuation component extraction function (optional) extracts fluctuations in sound and vibration caused by periodic fluctuations such as humming and chattering, and determines pass/fail.

■ Other Features

- Judgment assist function sets the judgment range based on the difference in frequency characteristics between good and bad products. - TEDS sensor support with automatic unit calibration (compatible with accelerometers and microphones version 0.9 and 1.0). - Open circuit detection function automatically detects cable breaks and connector defects when using constant current drive (CCLD) sensors. - Copy measurement data and conditions to a USB memory stick.
