Where : Ozone Conc.CTA = the ozone concentration calculated for each calibration test atmosphere (11.4.1). Ozone Conc.ZAS = the ozone concentration calculated for the zero air stream (11.3.1). 12.4 Instrument Calibration Curve - Plot the net ozone analyzer outputs, i.e., each calibration point (11.4) less the zero air (11.3); versus the respective net true ozone readings from either 12.1, 12.2 or 12.3. If the average percent difference between the ozone analyzer observations and the true ozone concentration is within + 10%, the analyzer is considered to be in calibration. 14.0 REFERENCES 16.
