Overview and features
The CF-4700 FFT comparator analyzes the frequencies of the sound and vibration coming from products and parts on
the manufacturing line and is thus the best FFT analyzer for acceptance judgment and quality inspection.
•
Setting up to 20 blocks that judge at the level of characteristic frequency signal is feasible (Further, setting six
different judgment approaches for each of the judgment blocks is feasible).
• An 8.4-inch color TFT-LCD (resistance film type touch panel unit) employed in this system helps the operator
readily watch waveforms and judgment results, and enables intuitive operations on the touch panel.
• The USB interface and SD card slot mounted enables measurement data and evaluation results to be saved to the
USB flash memory and SD card.
• The shape comparator function (optionally installed) allows the user to give a pass/fail judgment by waveforms.
• The tracking function (optionally installed) facilitates judgments from the level variation of a specific degree while
varying the revolution speed.
• The installed optional CF-0473 amplitude modulation component extraction function (bandpass envelop monitoring
function) enables checking the sound with headphones, thus operators can distinguish characteristic abnormal
sounds and make a judgment on them.
• In consideration of line measurement, the power source backup function (optionally installed) enables a normal
termination of units even in case of an instantaneous power failure or outage of the main power supply.
