Fault Details and Vibration Spectrum
The Tester collects data about vibration motion and
compiles this information in the time domain. Then, the
Tester transforms it into a frequency domain (spectra)
graph where the amplitude of the vibration signal is
graphed against the frequency or machine RPM.

Mechanical faults are detected at certain running speeds
or frequencies in the spectra. The algorithms identify, or
“cite” the abnormal vibration amplitude peaks (cited
peaks) at vibration spectra and then diagnose the
mechanical fault and severity.
To view fault information:
1. In the fault list, use the Dial to highlight the fault.

2. Push Details. The Tester displays a table of
cited peaks for the selected fault. Each fault is
associated with at least one cited peak.
