  • Page 2: Important Things To Remember

    In order to receive accurate measurements, please allow reading to stabilize for at least 2 minutes. The CN is not suitable for continuous emission testing. Please allow at least 10 minutes of fresh air purge for each hour of testing.

  • Page 4 Note: The CN constantly monitors the level of water in the water trap. When the condensate filter has fully expanded, the electrodes touch the electrode plate. This signals the pump to stop, protecting the sensors from harmful exposure. When this happens, it is time to change the expandable filter.

  • Page 5: Calibration Procedure

    Calibration Procedure For best results, the gas concentration should be as close to the expected levels of emissions as possible. Because each sensor is linear through a nominal range, one calibration gas concentration can be used for a reasonably wide range of emission levels. For applications with extremely low or extremely high levels of emissions, the sensors should be calibrated as close as possible to expected concentration levels.
