Sensor Diagram
Note: Function active for pH and oxygen sensors
The sensor diagram clearly indicates the status of the parameters in the connected sensor, including
the calibration timer.
Inactive parameters are shown in gray and set to 100% (e.g. disabled calibration timer).
The parameter values should lie between the outer (100%) and inner (50%) hexagon. A warning
signal flashes if a value drops below the inner hexagon (<50%).

Sensor Wear Monitor
Note: Function active for digital sensors
The sensor wear monitor shows the sensor operating time and the maximum temperature during the
operating time, as well as wear and the forecast remaining time. When using oxygen sensors,
the number of membrane replacements and calibrations is also displayed:
