6.11  Kurtosis 

The unit-less statistic index "Kurtosis" represents a very good indicator for the analysis in low 
(rotational) speed machines.  
To include the kurtosis as part of the vibration analysis, this function must be enabled by marking: 
"Enabled." The kurtosis value of a signal is a unit-less entity. 
 
A transient filter is used to remove unwanted non-periodical noise spikes in the vibration signal that 
might otherwise corrupt the measuring result and cause false alarms. 
The user can set/change the following parameters related to the kurtosis with the Compact Setup 
software: 

- 

End-value (unit-less) 
This value depends on the application but should never be defined as follows: 10.0 The default 
value for this parameter is: 20.00 

- 

RMS averaging time (in seconds). Selectable between 0.1 and 10.0 seconds. This value should 
never be below 3 seconds 
The default value for this parameter is: 3 seconds 

- 

Transient filter: enabled or disabled. This function is by default: enabled 

The calculation of the kurtosis is carried out within the bandwidth of the band-pass filter selected in 
band 2. Please keep in mind that the kurtosis function only makes sense for high frequency 
analysis, i.e. with a band 2 band-pass bandwidth starting at 2 kHz.
