SVAN 948 USER MANUAL
4 - 73
The view of the displays in 1/3 OCTAVE analysis with the acceleration spectrum expressed in LINear,
METRIC units; the first TOTAL value selected as HP acceleration filter; the second TOTAL value selected
as CH 2 and one of the displacement filters (Dil1) selected there or TOTAL 2 selected as USER VIBRATION
filter; the third TOTAL value selected as CH 3 and one of the displacement filters selected there (Dil1) or
TOTAL 3 selected as USER VIBRATION displacement filter
The view of the displays with the same vibration 1/3 OCTAVE spectrum presented as acceleration, velocity or
displacement in LOGarithmic units with the different DYNAMIC value (the <SHIFT> and <
> or <SHIFT>
and <
> push-buttons were also used for shifting up or down the vertical axis)
In the case when the logarithmic units are selected for the presentation of 1/3 OCTAVE analysis
results the displayed measurement values depend on the reference level set for the acceleration, velocity
and displacement in the REFERENCE LEVEL window of the SETUP list (path: MENU / SETUP /
REFERENCE LEVEL / VIBRATION).
The view of the displays with the different reference levels influencing the measurement vibration results
presented in the logarithmic units (decibels)
