Measurement data
・
The sampling rate is fixed at 4000sps (samples per second).
・
Measurement is carried out at 4000sps, but the data kept in a waveform is 2000 pieces per the
Measurement Length. (Maximum data: 2048)
Therefore, the waveform resolution is the Measurement Length/2000.
When the Time/Displacement Change setting is Time
During measurement, the load is sampled at 4000sps, and after completion of the measurement, the
load by resolution is kept in a waveform.
Example) When the Measurement Length is 1.0s
When the Time/Displacement Change setting is Displacement
The load and displacement are sampled at 4000sps, and the load is kept in a waveform every time
the displacement advances.
Example) When the Measurement Length is 4000mm
When the displacement returns, all the data of the corresponding load is recognized as that of the
previous displacement.
Example) When the displacement returns
