Calibrate the Wireless CO2 Sensor (SPARKvue)

updated for SPARKvue 4 at

How do I calibrate the Wireless CO2 Sensor (PS-3208) in SPARKvue software using a sample of fresh air? For the best calibration for your sensor, please have it powered on for at least four minutes to allow the device to come to thermal equilibrium. If you are going to be using the sensor in a high humidity environment, it can also be helpful to have the sensor at the temperature that you will be recording data to prevent condensation on the sensing elements.
