At any time, the computation parameters can be changed and the recompute button can
be used to update the results.
The Do Graph Autoscale button allows adjusting the Y and X scales for the new data of
the global historic graph.
The next table explains the computation parameters:
Computation parameter Description
The time step of the global level historic can be
adjusted between 50ms and 60000ms.
The dB/Lin. parameter allows choosing the amplitude
scale format. The choices are dB, dB(A), Lin. rms, Lin.
peak or Lin. rms
2 .
The Integration parameter allows application of simple
or double integration in the frequency domain for an
acceleration measurement. For the simple integration
option, the power spectrum is divided by jω. For the
double integration option, the spectrum is divided by –
ω
2 .
This is the time window used for the power spectrum
computation.
