CAUTION
• For purchasing optional measuring equipment, please contact your dealer or your local Ono Sokki sales office to let us help
you choose the equipment that suits your application and purpose.
• Connecting instruments other than those recommended by Ono Sokki or making modifications to the CF-4700 FFT
comparator may not only compromise the product performance but also result in failure or malfunction of the product, a fire or
an electric shock.

Inputting signals to signal input terminal (INPUT/EXT SAMP/EXT TRIG)
To execute the basic FFT analysis or tracking analysis, or making a judgment using the CF-4700 FFT comparator,
connect signals to the signal input terminal (INPUT/EXT SAMP/EXT TRIG) located on the rear panel. For details about
the specifications of signals to be input, refer to
“Input” on page 51
.
z
Connection of signals to be input to signal input terminal (INPUT)
Connect the signals from the sensors or measuring equipment to the signal input terminal (INPUT) so as to allow the
FFT analysis or the comparator function to make judgments on the input signals. A condition for the input signals can be
configured on the Input Condition Setting dialog box that is displayed after touching the following soft keys in the order
mentioned: Home, Input and Input Cond . (For details, refer to the Reference Guide included in the attached CD-ROM.)
z
Connection of the revolution signals to be input to the external sample signal input terminal (EXT SAMP)
To measure the signals in proportion to revolutions, input revolution signals to the external sample signal input terminal
(EXT SAMP) so as to enable the order analysis.
The revolution signals can be input through our MP-981 electromagnetic detector (to which signals are input through the
TM-3100 series digital tachometer) or HT-5000 series handheld digital tachometer.
To execute analysis for the external sampling signals, the optional CF-0471 tracking function is required.
A condition for the input sampling signals can be configured on the
Rotation Condition Setting
dialog box that is
displayed after touching the following soft keys in the order mentioned: Home, Input and Ext Sample . (For details, refer
to the Reference Guide included in the attached CD-ROM.)
z
Connection of a trigger signal to be input to external trigger signal input terminal (EXT TRIG)
To start executing measurement or judgment via an external device, a trigger signal must be input to the external trigger
signal input terminal (EXT TRIG).
A condition for the input external trigger signal can be configured on the External Trig Setting dialog box that is displayed
after touching the following soft keys in the order mentioned:
Home, Input, Trigger, and Ext Trigger.
(For details, refer
to the Reference Guide included in the attached CD-ROM.)
