4.5.3 Configuring Logger trigger
– Logger Trigger
In the
Logger Trigger
screen, you can configure the
way the logger results are to be registered in the logger
file. It is a context list of parameters in which the trigger
can be switched
Off
or On by selecting its type (
Level+
or
Level
–
) in the
Trigger
position.
<ENT>
When the trigger is selected, other parameters appear in the list: a measured result that is checked for a
trigger condition (
Source
), a threshold level (
Level
) as well as a number of results saved in the logger
before the trigger condition is met (
Pre
) and the number of the results saved in the logger after the last
trigger condition is met during logging (
Post
).
Note: In the Simple interface mode, the Logger Trigger position is hidden, but the instrument
will use settings previously defined in the Advanced mode or default settings (Trigger: Off)
.
Level trigger
The
Level+
/
Level
–
trigger enables logging of the time-history results
(
Logger Results
) with the
Logger Step
under the condition: value of the LEQ
result (
Source
) averaged by the
Logger Step
period is greater/lower than the
threshold value (
Level
). In other cases, the logging is skipped. Due to this type
of trigger it is possible to separate results related to the low/high noise level.
The logging is active only when the
summary results are measured, i.e. from
the
measurement
start
till
the
measurement stop.
This means, for example, that when the
measurement is waiting for a trigger
condition, logging is skipped, even if the
logger trigger condition is met.
Note:
When logging is waiting for the level trigger the “level” icon
appears alternatively with the „logger” icon.
/
Source result
Only one measured result (
Source
) can be used for checking trigger condition in the
Level Meter
mode,
namely the instantaneous LEQ from the first profile (with appropriate filter and detector), which is denoted
here as
Leq(1)
. This position cannot be changed.
Threshold level
The threshold value (
Level
) can be set in the range from
24 dB
to
136 dB
. The
Source
value compares with the
Level
value every 0.5 milliseconds.
