(a) Prior to its introduction into service and monthly thereafter the NDIR carbon dioxide
analyzer shall be calibrated:
(1) Follow the manufacturer's instructions for instrument startup and operation. Adjust the analyzer to optimize performance.
(2) Zero the carbon dioxide analyzer with either zero grade air or zero grade nitrogen.
(3) Calibrate on each normally used operating range with carbon dioxide in N2 calibration gases with nominal concentrations of 15, 30, 45, 60, 75, and 90 percent
of that range. Additional calibration points may be generated. For each range calibrated, if the deviation from a least-squares best-fit straight
line is 2 percent or less of the value at each data point, concentration values may
be calculated by use of a single calibration factor for that range. If the deviation exceeds 2 percent at any point, the best-fit non-linear equation
which represents the data to within 2 percent of each test point shall be used to
