calibration relationship. A minimum of three reference points and one zero point uniformly spaced
covering 0 to 90 percent of the operating range are recommended to define this relationship.
The analyzer's recorded response is compared with the known concentration to derive the
calibration relationship.
To perform a precision check, the instrument set up, sources of zero air and sample gas should
conform to those described in Section 7.2.
Follow the procedures described in section 7.2 for calibrating the zero points.
For each mid point:
SPAN CAL M RANGE = 500.0 PPB SO 2 X.XXX
< TST TST > ZERO SPAN CONC EXIT
Wait until
SO2 STB falls
below 0.5 ppb.
This may take
several minutes.

8.6. Special Calibration Requirements for Independent
Range or Auto Range
If Independent Range or Auto Range is selected, then it should be calibrated for both Range1 and
Range2 separately.
For zero and span point calibration, follow the procedure described in Section 7.2. Repeat the
procedure for both the HIGH and LOW Ranges
