Operating frequency range
Frequency range 0.5 Hz to 315 Hz
Acceleration and velocity, displacement signal select
band limitation such that the frequency range is as
follows.
lower: 0.5 Hz, 1 Hz, 4 Hz
upper: 80 Hz, 100 Hz, 250 Hz,
or Sensor dependent
However, when frequency weighting Wb, Wd specifi ed
by ISO is selected, the frequency range of acceleration
signal processing automatically ranges from 0.5 Hz to
80 Hz. 1 Hz to 80 Hz for Wm.
Measuring range
For setting the measurement frequency range, specify
the following measurement range from 1 Hz to 80 Hz.
