Model 300E Carbon Monoxide Analyzer
The Full Scale limit at which the output range of the
analyzer's ANALOG OUTPUTS are currently set.
THIS IS NOT the Physical Range of the instrument. See
Section 6.4 for more information.
Standard deviation of CO Concentration readings. Data
points are recorded every ten second. The calculation uses
the last 25 data points.
The demodulated, peak IR Detector output during the
MEASURE portion of the CFG Wheel cycle.
The demodulated, peak IR Detector output during the
REFERENCE portion of the CFG Wheel cycle.
The result of CO MEAS divided by CO REF. This ratio is the
primary value used to compute CO concentration. The
value displayed is not linearized.
The absolute pressure of the Sample Gas as measured by a
solid state pressure sensor located inside the Sample
Chamber.
Sample mass flow rate. This is computed from the
differential between the pressures measured up-stream
and down-stream of the Sample Critical Flow Orifice
pressures.
The Temperature of the gas inside the Sample Chamber.
Optical Bench Temperature.
Filter wheel temperature.
The temperature inside the analyzer chassis.
The drive voltage being supplied to the thermoelectric
coolers of the IR Photo-Detector by the Sync/Demod
Board.
The sensitivity of the instrument as calculated during the
last calibration activity. The Slope parameter is used to set
the span calibration point of the analyzer.
The overall offset of the instrument as calculated during
the last calibration activity. The Offset parameter is used
to set the zero point of the analyzer response.
Displays the signal level of the TEST Analog Output
Channel. Only Appears when the TEST channel has been
activated.
The current time. This is used to create a time stamp on
iDAS readings, and by the AutoCal feature to trigger
calibration events.
