Calibrate a PASPORT Carbon Dioxide Gas Sensor

How do I calibrate a PASPORT carbon dioxide gas sensor (PS-2110) to the concentration of carbon dioxide that is standard for an air sample?

If the audio volume is too low for you, please view a louder version at youtu.be/cbSSsIq96Hc.

NOTE: Newer Carbon Dioxide Gas Sensors reverse the blinking light behavior (for consistency with our Oxygen Gas Sensor), but the calibration process is otherwise the same.

Looking for the procedures for the Wireless CO2 sensor? Here is the video for this process.
