Delta slope(only pH)
The device determines the difference in slope 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. The greater the change, the greater the
wear experienced by the pH-sensitive glass membrane as a result of chemical corrosion or
abrasion.
