Trigger Freq
Use the Left , Right Arrow keys to adjust the Trigger Frequency as required.
The available Trigger Frequencies depend on the operating function the dBAir sound
level meter is set to.
If the dBAir is set to use the Full Octave function, then the following Trigger Frequencies
are available: -
•
All, 16Hz, 31.5Hz, 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, 16kHz
If the dBAir is set to use the Third Octave function, then the following Trigger
Frequencies are available: -
•
All, 12.5Hz, 16Hz, 20Hz, 25Hz, 31.5Hz, 40Hz, 50Hz, 63Hz, 80Hz, 100Hz,
125Hz, 160Hz, 200Hz, 250Hz, 315Hz, 400Hz, 500Hz, 630Hz, 800Hz, 1kHz,

Set the Trigger Frequency so that the triggering point of the noise event audio recording
is isolated only to the frequency specified. The noise event audio recording is not
affected and records as normal.
If the Trigger Frequency is set to All then no individual frequency is used to determine
the triggering point of the noise event audio file.
If neither full or third octave functions are used, then the Trigger Frequency is set to All.

Use the Left , Right Arrow keys to adjust the Hours, Minutes and Seconds as required.
