During sensor calibration, the raw sensitivity of the sensor is measured and then a calibration is used to translate that sensitivity into a number. That number is known as the “span reserve’ and provides an easy way to know whether a sensor is in need of replacement. If a sensor has a span reserve over it’s in new condition. If the span value is between 70% and 99%, the sensor is ...
