9 Record Setup
Click on the button to go to the Record Setup interface.
The events are recorded when a specified trigger value is encountered on one or a combination of
axis on the accelerometer. The trigger signal type, trigger value and units and the axis to monitor are
set using the controls at the top of the interface.
Two record times are to be set. The first one is the record length before trigger and the second one
is the record time after trigger. The total record time for one event will be the sum of these two
durations. It is recommended to use a record time before trigger of at least 1 s to record the transient
occurring at a vibration event. The record time after event is usually longer and can range from 2 s for
short events up to 20 s for longer events.
After Before
The SPL (Sound Pressure Level) sampling rate is set from a variety of choices. The default rate is
0.05 s and is appropriate for all time weighting (Slow, Fast and Impulse).
The record folder is the directory in which the files will be stored. To change or create a new folder,
click on the field to display an explorer dialog allowing the change.
