Manual scaling of axes
If you disable the Automatic scaling option, you can select one of the preset,
equivalent units for axis scaling. The available scaling units depend on the type of
diagram (e.g. Hz or kHz with FFTs for frequencies, g, mg, m/s² or mm/s² for
acceleration values, "orders" for order spectrums, rotations for angular signals, s
or ms for time signals, etc.). The scaling for the axes can be set independently of
one another, i.e. you can specify any desired unit for the x- and y-axes individually.
1. Click the "Auto" checkbox to deactivate it.
2. Select one of the units provided in the X unit field.
3. Select one of the units provided in the Y unit field.
The axes are scaled independently of one another and can be modified
according to the settings that are selected.
Logarithmic scaling of the y-axis
It may be possible under certain conditions to present signals more clearly using
a logarithmic scale if they do not contain zero values or negative values. You can
therefore switch over to logarithmic scaling in the diagram.
1. Click on the Log checkbox to activate the logarithmic scaling of the y-axis.
The scaling of the diagram will be modified according to the settings selected.
Displaying y-axis integrations
You have a number of display options for the integration of signals in FFT
diagrams that contain an acceleration signal, for example:
No integration: Acceleration
Velocity
Displacement
1. In the Integration field, select the Acceleration option to not integrate the
signal.
2. In the Integration field, select the Velocity option to display the first integration
of the signal.
3. In the Integration field, select the Path option to display the second integration
of the signal.
The scaling and display of the diagram will be modified based on the selected
settings.
This option is deactivated if the measurement data cannot
b e presented logarithmically (if the it contains values
smaller than or equal to zero, for example).
