Waveform
Waveforms show how vibration levels change with time. A vibration waveform chart represents a series of equally spaced discrete sample points connected by straight lines. The chart shows the vibration level (amplitude) at each time interval during the measurement period. The more sample points in a spectrum the higher the resolution of the waveform (but the more memory used).
The key parameters you need to set are the duration and number of samples.
The duration determines the equivalent Fmax value. If the waveform is later transferred to the Ascent program and displayed as a spectrum this Fmax value will be used on the chart.
The number of samples controls the number of spectral lines used when the waveform is transferred to the Ascent program and displayed as a spectrum.
- From the Main Menu press
Measure then press
Spectrum Waveform. - Use the left-hand arrow keys to select a parameter set or create a new one by pressing
and setting the parameters as required. - Press
to begin measuring.
