Example 1
In the instrument, the measurement of the 1/3-octave spectrum is set in the "Full" band in the sound
measurement mode. We want to take the following results every second:
- measurement time (with seconds resolution),
- overload information,
- second profile Peak results,
- first profile Leq results,
- 1/3-octave results between 20.0Hz to 20kHz (without Total results).
To do this, we send command:
#R,1,G,V,P:2,R:1,X:14:31;
In response instrument sends:
#R,1,G:0,V,P:2,R:1,X:14:31;
After measurement start, instrument will send below data every second:
#R,13:27:54,0,93.54,71.29,60.67,63.57,69.93,75.29,87.73,75.24,66.34,63.63,60.82,66.65,61.17,71.03,66.60

etc.
Interpretation of the data obtained from the first measurement is as follows:
13:27:54
– time of start of current measurement second,
0
– no overload,
93.54
– second profile Peak result in dB
71.29
– first profile Leq result in dB
60.67
– 20.0Hz spectrum band result in dB,
63.57
– 25.0Hz spectrum band result in dB,
(...)
51.75
– 16.0kHz spectrum band result in dB,
56.18
– 20.0kHz spectrum band result in dB,.
