Kimo DB 200 - 5.4 Sound Level Meter and Averager Integrator with Storage

5.4 Sound level meter and averager integrator with storage function
The sound level meter processes the acoustic signal for each elementary integration time and stores results in a saved memory.
Measured and stored data for each integration time:
• LXeq, DI : equivalent continuous sound level of acoustic pressure on the logging time and frequency weighted.
• LUpk : level of maximum peak of sound pressure on the elementary integration time.
• Measurement time expressed in DD/HH:MM:SS
Integration time :
Data storage is made according to logging time (DI) to choose from : 1s, 2s, 3s, 5s, 10s, 15s, 30s, 60s.
Note : In order to have permanent control of the sound pressure level before the launch of measurement, the sound level meter
calculates and displays the equivalent continuous level of acoustic pressure on a logging time of 0.5s.
5.4.1 Adjustment prior to measurement
1 – Select Leq-St mode : move the cursor with arrow keys to 1 and select 'Leq-St' with the scrolling knob key.
2 – Select the weighting frequency.
Possible choices are : A frequency weighting - C frequency weighting - Z frequency weighting.
Place the cursor with arrow key on the area 2 and select with scrolling knob A, C or Z.
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 the DI logging time :
Place the cursor on 4 and select with the scrolling knob among :
1s, 2s, 3s, 5s, 10s, 15s, 30s, 60s.
5.4.2 Launch the measurement
In manual mode : directly press icon ,the timer starts and shows the measurement time
In I/O mode : see chapter « Launching a measurement in I/O mode ».
5.4.3 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.
• LXeq0,5 : equivalent continuous level of acoustic pressure over a systematic integration time of
0,5s.
• LXeqDI : equivalent continuous level of acoustic pressure over the scheduled elementary
integration time
• LXeq : equivalent continuous level of acoustic pressure on ongoing measurement time.
• LUpk : level of maximum peak of sound pressure on the measurement time.
• Measurement time expressed in DD/HH:MM:SS
