  • Page 50: Calibration And Zero Checks

    G. Calibration and Zero Checks Calibration and Zero Checks It is recommended that the user frequently examine the data from the AQSync to be sure that the readings make sense and the instruments are working properly. For example, on polluted days ozone readings should be higher, and other pollutants such as particulate matter might be higher (especially if fires are burning nearby, for example).

  • Page 51: Co Instrument

    G. Calibration and Zero Checks 1. Power up the AQSync. For an accurate measurement, the ozone instrument must have been turned on long enough for the internal temperature to stabilize (normally ~20 minutes). 2. After the instrument is warmed up, make note of the time and collect data for at least 3 times the upload frequency (typically 5 min), so collect for 15-25 minutes.
