Setting the Frequency Filter
Set a filter to ignore or detect the changes in a specific frequency in the measured data.

Task Settings window : [Filter]
• Set the cut-off frequency to a value smaller than one-half of the sampling frequency. Otherwise, the frequency filter
will not function properly. If a value outside of the appropriate range is set, the frequency filter will be applied with
the values included in the range.
• If the cut-off frequency values (upper/lower limits) are too close, the frequency bandwidth to be detected cannot be
properly detected.
• The sampling frequency is the inverse of the measuring cycle.
• The measuring cycle can be viewed in the "System Information" menu on the Sensor Controller.

Description
Frequency filter
Frequency filter
OFF (default value)
Frequency filter is not used.
Lowpass filter
Ignores frequency components larger than the specified
cut-off frequency. (Only gradual changes are captured.)
Highpass filter
Detects frequency components smaller than the specified
cut-off frequency. (Sudden changes are captured.)
Bandpass filter
Detects the frequency components between the cut-off
frequency (lower limit) and the cut-off frequency (upper
limit).
Cutoff frequency
0.001 (default value) to
999.999 [Hz]
Set this item when a low pass filter or a high pass filter is
selected.
Cutoff frequency (Upper
limit)
0.001 (default value) to
999.999 [Hz]
Set this item when a band pass filter is selected.
Cutoff frequency (Lower
limit)
1
Select the frequency filter type from
[Frequency filter].
2
Set the cutoff frequency from [Cutoff
frequency]. When a band pass filter is
selected, set [Cutoff frequency (upper limit)]
and [Cutoff frequency (lower limit)].
The frequency filter can also be set by the operating keys on the Sensor Controller.
