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:
Step 1 - Enter the expected SO
2
span gas concentration
Step Number Action Comment
1. Press CAL-CONC This key sequence causes the 6200A to prompt for the
expected SO
2
concentration. Enter the SO
2
span concentration
value by pressing the key under each digit until the expected
value is set.
2. Press ENTR ENTR stores the expected SO
2
span value. This value will be
used in the internal formulas to compute subsequent SO
2
concentration values.
3. Press EXIT Returns instrument to SAMPLE mode.
4. Press SETUP-
RNGE-SET
If necessary you may want to change ranges. Normally the
instrument is shipped with range set at 500 ppb.
5. Press EXIT Returns the instrument to SAMPLE mode.
