SV106A User Manual
If
Slope +
is selected, the measurement starts when the arising result value
(
Source
) passes above the level determined by the
Level
position.
If
Slope
–
is selected, the measurement starts when the falling down result
value (
Source
) passes below the level determined by the
Level
position.
The measurement is stopped when the conditions set in the
General Settings
sub-list are fulfilled or after pressing the
<Start/Stop>
push-button or after receiving the proper control code remotely.
Next sources of the triggering signal are available:
RMS(1)
,
VEC46
,
VEC13
or
External
.
External
source
means that the triggering will be initiated by the positive or negative slope of the signal on the input/output
socket (
I/O
).
If
Level +
or
Level
–
is selected the triggering condition is checked every 5
milliseconds and the measurement is recorded only when the result value
(
Source
) has the greater / lower level than that determined in the
Level
position, otherwise the measurement result is skipped.
Next sources of the triggering signal are available:
RMS(1)
,
VEC46
or
VEC13
.
If
Gr
is selected, the triggering condition is checked every 5
milliseconds and the measurement is recorded only when the result value
(
Source
) has a greater level than determined in the
Level
position and the
gradient of the signal is greater than determined in the
Gradient
position.
Otherwise the measurement result is skipped. Only one source of the
triggering signal is available:
RMS(1)
.
Checking the triggering condition
The triggering condition is checked every 5 milliseconds. The position
Trig. Step
indicates this.
Selection of the triggering signal
The user can select several sources for the
trigger signal: vectors (
VEC13
and
VEC46
),
RMS of the first profile (
RMS(1)
) and
external signal of the I/O socket (
External
).

Setting the channel of the triggering signal
The
Channel
parameter denotes the channel of the triggering signal.
Setting the level of the triggering signal
The
Level
position enables the user to select the value of the threshold for
triggering condition. The level of the triggering source can be set in a range
from
60 dB
to
200 dB
or from
1.00 mm/s
2
to
10.0 km/s
2
, depending on the
scale type selected in the
Scal
e position (
path: <Menu> / Display /
Results Scale
).
