3. of 16 Sampling Data Logger User Manual CO2Meter To ensure maximum accuracy it is recommended to install the device in an environment that will routinely see this low value Alternatively the unit can be exposed to fresh air for a few minutes periodically or set the ABC period to O sec to perform a calibration as specified in the next section Calibration The calibration process varies depending on the type of unit and whether it has optional data logging functionality or not All units are factory calibrated with multiple reference points of gas and have been verified to be accurate within their specific functionality before shipment However if the unit is severely jolted or otherwise mechanically disturbed the sensor can drift requiring recalibration All calibration procedures follow a single point calibration routine that effectively shifts the zero point of the CO2 sensor Attach calibration gas to the unit and connect it to a personal computer Open the calibration screen in the GasLab software Click the Calibrate button in the calibration tab for the desired gas located in the Configure Sensor screen As long as the gas concentration is stable the unit should instantly reflect the calibrated value This can be confirmed by watching the display To see the calibration value in real time click in the Collect Real time button to capture these values before opening the configuration screen Gaslab v2 0 6 67 Gr
4. of Operation The CO2 sensor inside this device uses non dispersive infrared technology to sense as a function of transmitted light the concentration of CO2 in the air It has been factory calibrated to operate within the specified range and precision 0 1 and 0 30 Units Only The sensor uses an algorithm called Automatic Background Calibration ABC to continuously adjust the zero point to ensure accuracy is maintained This is required to compensate for sensor drift which occurs normally on these units The primary contributor to sensor drift is the normal and unavoidable aging of the infrared light source within the sensor The ABC algorithm allows the CO2 sensor to dynamically shift its CO2 reading by a constant It works via storing the lowest CO2 sample taken over the ABC period and assuming that this low value is equal to a known value the target value It then adjusts the output of the CO2 reading by the delta between these values This algorithm does not affect the linearization of the output signal For example the ABC algorithm is enabled by default with an ABC period of 180 hours a target value of 400ppm and a maximum delta of 30ppm This operates under the principle that a CO2 level in ambient outdoor air is 400ppm The sensor will keep track of the lowest CO2 reading recorded over a period of 180 hours and then adjust the zero point based on the lowest CO2 level recorded up to 30ppm at a time towards that value PAGE 11
