0 - none,
1 - by measurement,
2 - by sensitivity,
3 - factory calibration,
hh:mm:ss – time of calibration,
DD/MM/YYYY – date of calibration,
cF – calibration factor in dB.
cL – calibration level in dB.
Response #7,CH,-1; denotes incorrect data in
the selected record
Last calibration type
AF
Previously performed calibration type
0 - none
1 - By Measurement (manual)
2 - Remote
3 - Factory Calibration
4 - Auto Calibration
Last calibration date and time
CT
Function returns calibration date and time in the
format: #7,CT,DD-MM-YYYY,hh:mm:ss; where
hh:mm:ss denotes the time and DD/MM/YYYY
gives the date
AG
Last calibration date
d - coded data (0  65535)
Date decoding in C language:
day = (d & 0x1F);
month = ((d>>5) & 0x0F);
year = ((d>>9) & 0x7F) + 2000;
AH
Last calibration time
t - t coded time (0  65535)
Time decoding in C language:
sec = (t%30);
min = ((t/30)%60);
hour = (t/1800);
Note: time resolution is 2 seconds!
Calibration level
AI
nnnn - calibration reference level [dB]
multiplied by 100
