  • Page 56: Calibration

    Calibration Calibration adapts the device to the individual sensor characteristics. For best performance, you should always calibrate in air. Compared to water, air is a calibration medium which is easy to handle, stable, and thus safe. In the most cases, however, the sensor must be removed for a calibration in air.
