■ Setting the frequency filter
Set a filter to ignore or detect the changes in a specific frequency in the measured data.
Setting [Display]
Lowpass Filter [LO.PASS]
Highpass Filter [HI.PASS]
Bandpass Filter [BD.PASS]
Off [OFF]
(Default value)
*1
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.
*2
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 sampling cycle.
• The measuring cycle can be viewed in the "System Information" menu.

Setting the Output Conditions
Description
Ignores frequency components larger than the specified
cut-off frequency. (Only gradual changes are captured.)
Range of cut-off frequency: 0.001 - 999.999 Hz
(Default value: 0.001)
Detects frequency components smaller than the
specified cut-off frequency. (Sudden changes are
captured.)
Range of cut-off frequency: 0.001 - 999.999 Hz
(Default value: 0.001)
Detects the frequency components between the cut-off
frequency (lower limit) and the cut-off frequency (upper
limit).
Sets the upper and lower limits of the frequency
bandwidth to be detected.
Range: Upper limit 0.001 - 999.999 Hz
(Default value: 999.999)
Lower limit 0.001 - 999.999 Hz
(Default value: 0.001)
Frequency filter is not used.
