7.2 Calibration

 The CLD and the HCLD shall be calibrated in the most common operating range, following the manufacturer's specifications using zero and span gas (the NO content of which should amount to about 80% of the operating range and the NO2 concentration of the gas mixture to less than 5% of the NO concentration). The NOx analyser must be in the NO mode so that the span gas does not pass through the converter. The indicated concentration shall be recorded.
