Relationship between the maximum measurement range and frequency
The maximum measurement range of this instrument is, as shown in the vibration monograph
(rms value) below, dependent upon the acceleration (ACC) and frequency. Setting of the range
at velocity (VEL) and displacement (DISP) modes shall be made by acceleration (ACC).
If acceleration (ACC) exceeds 20 m/s
2
, make sure to use 200 mm/s range for the velocity (VEL),
and 2000μm range for the displacement (DISP).
* Relationships between acceleration, velocity and displacement are expressed per following
equations.
When the maximum measurement range of acceleration (ACC) is 200m/s
2
rms, the
maximum frequency that can measure the maximum measurement range of 200mm/s rms
for the velocity (VEL) is approx.159 Hz
When the maximum measurement range of acceleration (ACC) is 200m/s
2
rms, the
maximum frequency that can measure the maximum measurement range of 2000μm p-p
(707μm rms)for the displacement (DISP) is approx. 85 Hz.
