chronous vibration components

vibration components
29 Total value F
Weighted sum for all lines of a frequency spec-
trum.
30 Residual value F
Weighted sum for all lines of a frequency spec-
trum, excluding the lines of harmonic com-
ponents
Type: T = determined from time signal, F = determined from frequency spectrum,
2 = determined from 2 source channels
Scaling
Scaling automatically taken from source channel (for amplitude values) or appro-
priately preset (for frequencies or phase angles).
Application
Analysis of characteristic values of a vibration signal – for time and frequency
ranges. For example, determining the root mean square of a vibration signal or the
peak amplitude of a spectrum.
Mathematical definition
Mathematical definitions for all the available characteristic values are listed in the
following sections.
9.2.5.1
"Maximum value", "minimum value" characteristic values
Maximum value
The DSP determines (finds) the maximum value (or highest positive value) of the
time signal and delivers the amplitude value.
