Frequency filter Frequency filter OFF (default value) Frequency filter is not used.
Lowpass filter:
0.040 to 23735.000
(default value: 0.040)
Ignores frequency components larger than the
spe
cif
ied cut-off frequency. (Only gradual changes
are captured.)
Highpass filter:
3.000 to 23725.000
(default value: 23725.000)
Detects frequency components smaller than the
spe
cif
ied 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 Refer to the table below. Set this item when a low pass filter or a high pass
filter is sele
cted.
