Delta zero point
The device determines the difference between the last calibration and the penultimate
calibration, and issues a warning or an alarm depending on the setting configured. The
difference is an indicator for the condition of the sensor. Increasing differences indicate the
formation of buildup on the cathode. Clean the cathode as specified in the instructions in the
sensor operating manual.
