Measurement
Measurement
Carry out the measurement by pushing the tip of the accelerometer PV-55 at a
right angle against the measurement object. Application pressure should be
between 0.5 and 2 kgf.
Use the START key and STORE key to control the measurement.
In time waveform display, only the first 128 data out of the sampled data are
shown. If required, these are compressed for display. When the zoom factor is
1, 256 data are sampled but only 128 data are displayed. When the zoom factor
is 2, 512 data are sampled, and the first 256 data are compressed and displayed
as 128 data. By setting the X axis zoom factor to 2, the compressed part can be
enlarged for display.
Overflow indication
Because only the first half of the sampled data is displayed, it is possible that
the overload indicator appears although the waveform shown on the display
does not exhibit overload. This means that overload has occurred in the second
half of the sampled data.
