3. 10 seconds pre-trigger is set.
4. Capture of Voice notes before a run are enabled.
In this mode when the meter is switched on then the CEL-63X automatically
enters calibration mode. If a calibration is not done after 30 seconds this will
time out then the meter will switch to allow Audio notes to be recorded. Again
this will time out after 30 seconds and automatically start a measurement so if
no keys are pressed during the power on sequence then the meter will start a
run after just over a minute.
This mode is designed to be used with a Stealth TM Noise Nuisance Record Kit.
Whenever the button on the kit is pressed then an external event is started or
extended (see external event details above). The LED will flash to show the
event audio is being saved. When the maximum event time is reached then the
LED is switched off. If memory is low then during an event the LED will be
continuously lit to show an event is in progress but the event audio is NOT
being recorded. When the LED is off then an event is NOT in progress.
At the end of a NRR run the user is prompted to do an after-run calibration.
Note: if memory is low or an NRR run is delayed using the start/stop timers or
the NRR run is not the first run in a sequence of runs then the voice notes
option is skipped. Voice notes can however always be added after the run is
completed.
