Converter efficiency check After maintenance of APNA you have to check and adjust the converter efficiency: • Change to Supervisor Modus 8/9 FACTORY CALIBRATION

• Introduce zero gas and calibrate zero point

• Introduce NO span gas and calibrate span point

• Introduce GPT this means NO is converted to NO2 by using ozone

• If the measured value is stable, adjust the number of the EFFICIENCY until the

NOx value is the same like before without GPT.
