Thermo Fisher Scientific TVA2020 Instruction Manual 8-15
If digital data logging is enabled, streaming concentration data is sent out
via Bluetooth at the end of each measurement cycle (once per second)
when the analyzer is in RUN mode. The digital data format is as follows:
Digital data log record:
pppppppppp sssssssss ffffffffff sssssssss aaaaaaaaa ooooooooo hhhh rr nn <CR><LF>
where:
pppppppppp = PID concentration, floating point, right justified,
leading spaces, or
" “ when PID detector not selected
ffffffffff = FID concentration, floating point, right justified,
leading spaces, or
" “ when FID detector not selected
sssssssss = data status:
" ", detector not selected
"OK ", no errors or alarms
"DET_OFF ", detector not valid
"DET_FAIL ", detector failed, not "DET_OFF"
"OVERFLOW ", A/D overflow, not "DET_FAIL"
"UNDERFLOW", A/D underflow, not "OVERFLOW"
"BAD_CALIB", invalid calibration parameters
"CAL_SLOPE", calibration sensitivity out of range
"CLAMPED ", an intermediate concentration exceeded 100%
"AVG_OVFLW", during log point averaging, an overflow occured
"HIGH_ALRM", high alarm, no STEL, not "UNDERFLOW"
"LOW_ALARM", low alarm, no high alarm or STEL, not "UNDERFLOW"
"STEL_ALRM", STEL alarm, no low or high alarm, not "UNDERFLOW"
"HIGH&STEL", high alarm and STEL, not "UNDERFLOW"
"LOW&STEL ", low alarm and STEL, no high alarm, not "UNDERFLOW"
Digital data logging is initially disabled and the logging type is set
according to what detectors are installed so, e.g., if only an FID is installed
the logging type will be set to FID data only logging.
