Main default settings
With the default settings, the instrument will measure sound pressure level by
three virtual meters, so called profiles (Measurement Mode: Sound;
Measurement Function: Level Meter) with 1 second delay from the <Start>
key pressure (Start Delay: 1 s), 1 second integration time (Integration Period:
00:00:01), infinitive repetition till press the <Stop> key (Repetition Cycle: Inf),
linear integration for the RMS base results (RMS Integration: Lin), linear
integration for statistics (Statistics: Lin), daytime limits for Lden calculations
(Day Time Limits: 6-18 h), time frames for two rolling Leq calculations
(Rolling Time(1): 30 m and Rolling Time2: 1 h), free field compensation
(Compensation Filter: Free Field), active logging of the selected results with
1 second step (Logger: On; Logger Step: 1 s; Logger Results: Peak, Max,
Min and Leq for all profiles) and summary results saving including Statistics.
The logger and summary results will be automatically saved in the file with the
name defined by the instrument and presented in the Logger Setup screen
(Logger Name: Lxxxx).
Other functions are switched off, like:

(Detector(1)=Fast);
Profile 2 - C weighting filter (Filter(2)=C), Fast RMS detector
(Detector(2)=Fast);
Profile 3 - Z weighting filter (Filter(3)=Z), Fast RMS detector
(Detector(3)=Fast).
Default profiles settings for Vibration measurements:
Profile 1 - HP1 weighting filter (Filter(1)=HP1); 1.0s RMS detector
(Detector(1)=1.0s);
Profile 2 - HP3 weighting filter (Filter(2)=HP3), 1.0s RMS detector
(Detector(2)=1.0s);
Profile 3 - HP10 weighting filter (Filter(3)=HP10), 1.0s RMS detector
(Detector(3)=1.0s).
