The instrument converts the dissolved oxygen pressure value from the sensor to %-saturation by dividing the sensor output in mmHg by 160*** (the pressure of oxygen in air at 760 mmHg) and then multiplying by 100. For example, a measured oxygen pressure of 150 mmHg would be displayed by a sensor as 93.8 %-saturation (150/160 * 100).
