The codes of results in the case of Sound Meter mode are defined as follows:
C number of measurement cycle;
V overload flag (c equals to 0 or 1);
T time of the measurement cycle (c
– value in seconds);
P Peak value (c
– the value in dB);
M Max value (c
– the value in dB);
N Min value (c
– the value in dB);
S Spl result (c
– the value in dB);
R Leq result (c
– the value in dB).
U SEL result (c
– the value in dB);
B(k) Lden result (c
– the value in dB); k – flag determining the kind of the result:
k = 1
–
Ld result,
k = 2
–
Le result,
k = 3
–
Lde result,
k = 4
–
Ln result,
k = 5
–
Lnd result,
k = 6
–
Len result,
k = 7
–
Lden result;
I LEPd result (c
– the value in dB).
Y Ltm3 result (c
– the value in dB);
Z LTeq result (c
– the value in dB);
g LR1 (rolling Leq 1
st
) result (c
– the value in dB);
h LR2 (rolling Leq 2
nd
) result (c
– the value in dB);
L(nn) statistic levels (c
– the value in dB);
O NR result (c equal to 131 means that NR result exceeds the maximum value for which is defined
– i.e.
130);
K NC result (c equal to 14 or 71 means that NR result exceeds the minimum or maximum value for which
is defined
– i.e. 15 or 70 respectively);
The codes of results in the case of VLM mode are defined as follows:
C number of measurement cycle;
V overload flag (c equals to 0 or 1);
T time of the measurement cycle (ccc
– value in seconds);
P Peak value (c
– the value in dB);
Q P
–P
value (c
– the value in dB);
M Max value (c
– the value in dB);
R RMS value (c
– the value in dB);
Example: After sending to the instrument the string:
#2,a,1,C?,V?,T?,P?,M?,R?;
the unit sends out the results of measurement coming from the first profile in predefined, described above,
order:
#2,a,1,C5,V0,T60,P125.41,M117.60,R105.43;
Note: All bytes of that transmission are ASCII characters.
