Teledyne API Model 100AH SO2 Analyzer Instruction Manual, 02417, Rev. D

The next task is to calibrate the analyzer. There are several ways to do a calibration; they are summarized in Table 7-1.For a preliminary checkout we recommend calibration with zero air and span gas coming in through the sample port. The procedure is:

WARNING – Analyzer Exhaust

Danger – Analyzer exhaust may contain high concentration of SO2 gas. Exhaust properly from the pump pack exhaust to well ventilated area at atmospheric pressure.

Step 1 - Enter the expected SO2 span gas concentration:

Step Number	Action	Comment
1.	Press CAL-CONC	This key sequence causes the M100AH to prompt for the
		expected SO2 concentration. Enter the SO2 span
		concentration value by pressing the key under each digit until
		the expected value is set.
2.	Press ENTR	ENTR stores the expected SO2 span value. This value will be
		used in the internal formulas to compute subsequent SO2
		concentration values.
3.	Press EXIT	Returns instrument to SAMPLE mode.
4.	Press SETUP-	If necessary you may want to change ranges. Normally the
	RNGE-SET	instrument is shipped in single range mode set at 500 PPM.
		(see Section 5.3.4 for Range Menu)
5.	Press EXIT	Returns the instrument to SAMPLE mode.
