Teledyne 05386D manual Span Calibration Procedure

Model 200EU-NOy Option Manual Addendum

Table 4 Enter Expected Span Gas Concentrations Procedure For NO & NOy

Step	Action	Comment
1.	Press	This key sequence causes the M200EU to prompt for the
	CAL-CONC-NOy	expected NOy concentration.
		Enter the NOy span concentration value by pressing the
		key under each digit until the expected value is set.
2.	Press ENTR	ENTR stores the expected NOy span value.
3.	Press	Now enter the expected NO span concentration as in step
	CAL-CONC-NO	one.
4.	Press ENTR	Pressing ENTR stores the NO span value and returns the
		prompt to the CONC menu.
5.	Press EXIT	Returns instrument to SAMPLE mode.

If desired, compensation for converter efficiency (CE) can be included in the NOy concentration calculation. Prior to calibration, the converter efficiency should either be set to 1.0 or determined per the procedure in the M200E manual.

Table 5 Span Calibration Procedure

Step	Action	Comment
1.	Press CAL	The M200EU enters the calibrate mode.
2.	Wait For Stability	Wait for reading to stabilize at span value.
	Type STB < 2 PPB
3.	Press SPAN	If you change your mind after pressing SPAN, you can
		still press EXIT here without spanning the instrument.
4.	Press ENTR	Pressing ENTR actually changes the calculation
		equations and causes the instrument to read the NO and
		NOy span concentrations.
5.	Press EXIT	M200EU returns to sampling. Immediately after
		calibration, data is not added to the DAS averages.
