SV 977D User Manual
4.4.3 Selecting additional summary results for saving – Summary Results
The Summary Results list allows you to
include/exclude logging of some summary
results, like: Statistics, Meteo,
Statistics Spectrum, Max Spectrum and
Min Spectrum for Sound measurements and
Meteo, Max Spectrum and Min Spectrum
for Vibration measurements. Default modes:
all enabled.
<ENT>
Note: Meteo results are transmitted to the instrument from the weather station connected to the
SV 277 monitoring station.
4.4.4 Configuring the Logger trigger – Logger Trigger
In the Logger Trigger list, you can configure
the way the logger results will be registered in
the logger file. It is a context list in which: the
trigger can be disabled (Off) or enabled by
selecting its type (Level+ or Level-) in the
Trigger position. Default value: Off.
<ENT>
When the trigger is enabled, other parameters appear in the list: measured result that is checked for a trigger
condition (Source), threshold level (Level) as well as number of results saved in the file before the first fulfilment
of the trigger condition (Pre) and after the last fulfilment of the trigger condition (Post) during the measurement
period
Level trigger
The Level + / Level - trigger enables logging of the Logger results with the
Logger Step on condition: value of the measured result (Source) averaged
over 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 „curve” icon.
or
Source result
Only one measured result (Source) can be used for checking trigger condition in the Level Meter mode, namely
the instantaneous RMS from the first profile (with appropriate filter and detector), which is denoted here as Leq(1)
in the sound mode and RMS(1) in the vibration mode. This position cannot be changed.
