EXAMPLE

The following example is from a turbine.

1. Process the tachometer signal to get the smoothed speed curve. See

“Process a Tachometer Signal.” If you do not have a tachometer signal,

skip this step.

2. Use Waterfall analysis to create the Waterfall plot. In order to use the

order tracking features, select both the smoothed machine speed curve

and the data channel in the Channel List window. If you do not have a

tachometer signal, select the data channel. Then do one of the

following:

• Click the Waterfall analysis button

• Choose Waterfall Analysis from the Analysis menu.

3. Press F1 for an explanation of the dialog box. After selecting the desired

parameters, choose OK to display the Waterfall plot.
