CO2 Sensor Calibration: What You Need to Know |

Zero calibration is based on the idea that if you show the sensor/device a 100% concentration of an alternate gas than it is measuring, the sensor/device should read absolute zero. By following this method of calibration, the user is flooding the sensing chamber with the alternate gas and driving out any trace amounts of the original gas.

Why does my CO2 sensor read zero after calibration?

The Carbon Dioxide IR sensor is calibration sensitive it needs to have a two-point calibration performed in the proper order. Zero calibration with 100% Nitrogen gas, zero air or any gas matrix that does not have CO2 to calibrate your baseline. Span calibration with 5000ppm (5%) CO2 gas. The 5000ppm Span value is the lowest span value that the ...

How to Reset the ECU After Changing an O2 Sensor | It ...

The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle's computer. The ECU then adjusts the air-to-fuel ratio to optimize the fuel combustion. Sometimes an O2 sensor fails, and you need to replace it. Once you've replaced your vehicle's O2 sensor, you'll need to reset the ECU so it can properly gather information from the new O2 sensor.
