SVAN 958A User Manual
By default:
- For vibration input HP filter is denote for the first Total value. Second
and third Totals have same filters as were set up for channel (CH) in
the Channels list (path: <Menu> / Measurement / Channels).
- For sound input A filter is assigned to the first Total value, C filter – for
the second Total value and LIN – for the third Total value.
It is also possible to select three user filters: FUSR1, FUSR2 and FUSR3 for
vibration input as well as SUSR1, SUSR2 and SUSR3 for sound input. When
user filter for vibration input is selected, two additional positions appear: Type
and Cal. Factor.
In the position Type the user can define the type of integration to present the
measured signal as acceleration (ACC), velocity (VEL) or displacement (DIL).
In the Cal. Factor position the user can define any additional calibration factor
which will be applied to the calculation of Total value.
The same settings can be performed for Total 2 and Total 3 values.
10.9 SETTING USER FILTER COEFFICIENTS FOR 1/1 AND 1/3 OCTAVE – USER FILTERS SETUP
The User Filters Setup position enables the
user to introduce the values of the user
frequency filters coefficients. This position is
active only in 1/1 Octave and 1/3 Octave
modes. The User Filters Setup position opens
the list in which the user can view, edit or clear
the filter coefficients for selected user filter
VUSR1, VUSR2 and VUSR3 for vibration inpun
(Mode=Vibration) or SUSR1, SUSR2 and
SUSR3 for sound inpun (Mode=Sound).
<ENT>
The Mode position enables the user to select
the measurement mode of the instrument:
Vibration or Sound.
With each mode a three user defined filters
(Filter) are connected:
- VUSR1, VUSR2 and VUSR3 for
vibration inpun and
- SUSR1, SUSR2 and SUSR3 for sound
inpun.
►
The View position opens the window with the
table of filter coefficients.
The values of these positions cannot be
changed.
