SV106A User Manual
5.3.1 Assignment channels for accelerometer axis - Channel/Axis Mapping
The
Channel/Axis Mapping
position enables the user to assign channels
to the transducer’s axis. The user can assign channels
1
,
2
,
3
to the axis X,
Y, Z of the first transducer, connected to the Lemo compatible type
ENB.0B.304 socket for
Channels 1
–3
and channels
4
,
5
,
6
to the axis X, Y,
Z of the second transducer, connected to the Lemo compatible type
ENB.0B.304 socket for
Channels 4-6
.
If same channel is assigned to the more than one axis there will be error
detected and the user will be prompted to reassign the channels.
5.3.2 Setting parameters for channels
– Channel x
The
Channel x
positions enable one to set
up or display parameters for the individual
channel, like input type and filters for
profiles.
If
Dosimeter
is active the first profile filter is
set by default and it cannot be changed.
When second profile is switched off the filter
for second profile doesn’t appear as
parameter in the list.
Input type and range selection
The following inputs are available:
Direct
,
IEPE, Building (Direct)
and
Building (IEPE)
.
The
Range
value cannot be changed; it always depends on the filter type
and calibration factor. If calibration factor is equal to zero the range is equal
to
126 m/s
2
.
Weighting filter selection
The following weighting filters are available for the first profile of the
instrument:
KB
,
Wh
,
Wk
,
Wd
,
Wc
,
Wj
,
Wm
,
Wg
,
Wb
,
Wf
and
BL Wc
. The
characteristics of the filters are given in App. D.
The set of filters for the second profile depends on the filter selected for the
first profile. There are always available
HP
and
Vel3
filters for second profile
with all combinations of filters for the first profile. Second available filter for
profile 2 is one of the following:
BL Wh
,
BL
Wk
,
BL Wd
,
BL Wc
,
BL Wj
,
BL Wm
,
BL Wg
,
BL Wb
and
BL Wf
; according to the rule
– if
Wh
filter is
selected in the profile 1 then apart from
HP
and
Vel3
only the
BL Wh
filter
is available for profile 2. If
Wk
filter is selected in the profile 1 then apart
from
HP
and
Vel3
only the
BL Wk
filter is available for profile 2. Same rule
is applied for other channels.
When
Dosimeter
function is active
б the filters for first profiles are predefined and dependend on the type of
dosimeter measurements for the channels
–
WBV
or
HAV
.
If
WBV
measurements are performed in channels
1-3
or
4-6
the filters defined for channels are as follows:
Channel 1 or 4:
Wd
, Channel 2 or 5:
Wd
, Channel 3 or 6:
Wk
.
If
HAV
measurements are performed in channels
1-3
or
4-6
the filters defined for channels are as follows:
Channel 1 or 4:
Wh
, Channel 2 or 5:
Wh
, Channel 3 or 6:
Wh
.
