CF-4700 FFT Comparator

A pass/fail judgement machine, perfectly suited to quality control on production lines.

The CF-4700 FFT comparator is a pass/fail judgment machine used on production lines, that is highly effective at accurate quality inspection by analysing sound or vibration from products. The CF-4700 enables pass/fail judgments by extracting the amount of fluctuation in signal size, focusing on a specific frequency band.


  •  Compact and lightweight with 1-channel FFT analyzer
  •  8.4 type touch-panel color LCD
  •  Offering 110 dB dynamic range. The real-time analysis is 40 kHz
  •  The Assist Function for setting the judgment block area from the difference between frequency characteristics of OK and NG products
  •  The Power Source Backup Function prevents loss of measurement data in case of a main power down. (Option)
  •  The binary, text and BMP file can be memorizes in the main unit at the same time
  •  Memory data or condition memory can be managed or backup in a PC by means of storing those data in USB memory
  •  Operating CCLD & TEDS.

* Note: If a TEDS supported sensor made by other companies is used, TEDS information may not be read depending on the type of a TEDS tip included in a sensor.

1. If you are considering the purchase of a TEDS sensor made by other companies, please consult to the manufacturer or dealer of the TEDS sensor, and perform the operation check.

2. When you want to use a TEDS sensor you already have with the TEDS supported measurement instruments made by Ono Sokki, please perform the operation check with a demonstration product of Ono Sokki. (Please consult your nearest distributor or Ono Sokki sales office nearby.)

* The TFT color LCD is created by the full use of advanced technology. However, the pixels (dots) of non-lighting or always lighting occasionally exist in the display. (The ratio of the number of effective dots: 99.999 % or more.) Also, unevenness of the color or brightness may be visible depending on the viewing angle or the temperature change. This is not a product failure, so please note that return or exchange of the product cannot be accepted.
