5.2 Conventional sound level meter with storage function

The sound level meter processes the sound pressure signal and stores with a sampling rate results in a saved memory.
Data measured and stored at a sampling rate :
Temporally weighted sound pressure level
•
Maximum and minimum levels on the measurement time.
•
Level of maximum peak sound pressure on the measurement time.
•
Sampling rate :
Stored data is made at a rate to choose from:
1s, 2s, 3s, 5s, 10s, 15s, 30s, 60s.

5.2.1 Adjustment prior to measurement

1 – Select L-St mode : move the cursor with arrow keys to 1 and select 'L-St' with the scrolling knob key.
2 – Select the weighting frequency and the time weighting.
For each weighting frequency, the sound level meter proposes the measurement according to three time
weightings : Fast (F) – Slow (S) – Impulse (I). Possible choices are :
A frequency weighting : LAF – LAS – LAI
C frequency weighting : : LCF – LCS – LCI
Z frequency weighting : : LZF – LZS – LZI
Place the cursor with arrow key on the area 2 and select with scrolling knob identified measurement
criteria among the possibilities listed above.
3 – Select the weighting frequency of peak level of sound pressure : move the cursor with the arrows to 3 and select C or Z with the
scrolling knob key.
4 – Select sampling rate : move the cursor to 4 and select with scrolling knob key among 1s, 2s, 3s, 5s, 10s,15s, 30s, 60s.

5.2.2 Launch the measurement

In manual mode : directly press icon
In I/O mode : see chapter « Launching a measurement in I/O mode »

5.2.3 During measurement

During measurement, three screens inform the current measurement. They are accessible through the
scrolling knob key.
E1 : it is the main screen that displays the instantaneous measurements.
E2 : This screen contains results of values that will be stored in memory at the end of measurement:
LUpk : maximum peak level of sound pressure.
•
LXYmax : maximum value of sound pressure level weighted temporally met since the beginning of
•
the measurement.
LXYmin : minimum value of sound pressure level weighted temporally met since the beginning of
•
the measurement.
D : measurement time in DD/HH:MM:SS
•
% : percentage of saturation of the input stage.
•
Statistics indices : L01 – L10 – L50 – L90 – L95. They are calculated from stored samples.
