In the SPECTRUM CONDITION
pop-up box, you can define a mask
for thirty one 1/3 octave bands
spectrum and three Total results. If
the
measured spectrum
( AVERAGED , INSTANT , MAX or
MIN ) will show the excess of the
levels ( Level + Mode ) or the
lowering of the levels ( Level -
Mode ) defined for the mask, then
the condition will be active during
Min. duration time.
To start mask creation, click the
field and select the
spectrum frequency or the Total
result.
Then select the threshold level for
that
frequency/Total in the
Thresholds position.
After confirmation ( OK ) the pop-up box closes, and the selection will be presented in the line of the
TRIGGER button.
The Meteo condition is similar to
the Threshold one and can be of
Level+ or Level- type ( Mode ) and
defines period during which the
controlled value of the selected
result
( Source ) will be
higher/lower than the Threshold
level.
You can select as a Source different results ( Max wind , Avg wind and Rain )
measured by: 1s , Summary results Integration period (for example, 1m, SR ) or
Time History step (for example, 50, TH ).
In the right-hand example, 1m, SR means that the Integration period was set to 1
minute, while 50, TH means that the Step for the Time-history was set to 50
milliseconds.
