Teledyne M300EM operation manual Table, Test Functions Defined

	Teledyne API – Technical Manual - Model 300E Family CO Analyzers				Basic Operation
			Table 6-2:	Test Functions Defined
	PARAMETER	DISPLAY TITLE	UNITS	MEANING
			PPB3, PPM	Standard deviation of CO concentration readings. Data points are
	Stability	STABIL		recorded every ten seconds using the last 25 data points. This
			UGM3, MGM	function can be reset to show O2 or CO2 stability in instruments with
				those sensor options installed.
		RANGE	PPB, PPM,	The full scale limit at which the reporting range of the analyzer is
	Range	1		currently set. THIS IS NOT the Physical Range of the instrument.
		RANGE11	UGM, MGM
		RANGE2		See Section 6.6.1 for more information.
	O2 Range 1	O2 RANGE	%	The range setting for the optional O2 Sensor.
	CO2 Range2	CO2 RANGE	%	The range setting for the optional CO2 Sensor.
	CO Measure	CO MEAS	MV	The demodulated, peak IR detector output during the measure
				portion of the GFC Wheel cycle.
	CO Reference	CO REF	MV	The demodulated, peak IR detector output during the reference
				portion of the GFC Wheel cycle.
	Measurement /	MR Ratio		The result of CO MEAS divided by CO REF. This ratio is the
			-	primary value used to compute CO concentration. The value
	Reference Ratio
				displayed is not linearized.
	Sample Pressure	PRES	In-Hg-A	The absolute pressure of the Sample gas as measured by a
				pressure sensor located inside the sample chamber.
	Sample Flow	SAMPLE FL	cm3/min	Sample mass flow rate as measured by the flow rate sensor in the
				sample gas stream.
	Sample	SAMP TEMP	°C	The temperature of the gas inside the sample chamber.
	Temperature
	Bench	BENCH TEMP	°C	Optical bench temperature.
	Temperature
	Wheel	WHEEL TEMP	°C	GFC Wheel temperature.
	Temperature
	Box Temperature	BOX TEMP	°C	The temperature inside the analyzer chassis.
	O2 Cell	3
	Temperature3	O2 CELL TEMP	°C	The current temperature of the O2 sensor measurement cell.
	Photo-detector	PHT DRIVE	mV	The drive voltage being supplied to the thermoelectric coolers of the
	Temp. Control
				IR photo-detector by the sync/demod Board.
	Voltage
	Slope	SLOPE	-	The sensitivity of the instrument as calculated during the last
				calibration activity.
	Offset	OFFSET	-	The overall offset of the instrument as calculated during the last
				calibration activity.
	O2 Sensor	O2 SLOPE	-	O2 slope, computed during zero/span calibration.
	Slope 1
O2 Sensor Offset 1		O2 OFFSET	-	O2 offset, computed during zero/span calibration.
	CO2 Sensor	CO2 SLOPE	-	CO2 slope, computed during zero/span calibration.
	Slope2
	CO2 Sensor	CO2 OFFSET	-	CO2 offset, computed during zero/span calibration.
	Offset 2
	Current Time	TIME	-	The current time. This is used to create a time stamp on iDAS
				readings, and by the AUTOCAL feature to trigger calibration events.
