Slope
This parameter only appears for pH electrodes.
Slope of the pH electrode. With a 1-point calibration, only pH(0) can be
calculated, 100.0 % is used as the slope.
Input range –999.9 - 999.9 %
Default value 100.0 %
pH(0)
This parameter only appears for pH electrodes.
pH value of the pH electrode at 0 mV. Apart from the slope, pH (0) is the
second characteristic of the calibration curve.
Input range –20.000 - 20.000
Default value 7.000
Calibration temp.
This parameter only appears for pH electrodes.
Temperature at which the last calibration was carried out.
Input range –20.0 - 150.0 °C
Default value 25.0 °C
Calibration date
This parameter only appears for pH electrodes.
Date of the last calibration.
Monitoring
This parameter only appears for pH electrodes.
Activating and deactivating the calibration monitoring.
Selection on | off
Default value off
Time interval
This parameter is visible only when Monitoring = on.
You will be notified that this time interval (in days) has elapsed when start-
ing a method. You can then select whether or not you would still like to
start the method.
Input range 1 - 999 d
Default value 999 d
