Record message
The message that the working life of the sensor has expired will be auto-
matically saved with the determination.
Display message
A message is displayed and you can choose whether you want to con-
tinue the run or cancel it. If the run is continued, then the message that
the working life of the sensor has expired will be saved automatically with
the determination.
Stop determination
The running determination will be automatically canceled. The following
message must be confirmed with [OK].

Specific calibration data for pH electrodes
Slope
Slope of the pH electrode. This value can be determined automatically with
a calibration from the linearized calibration curve or entered manually. The
slope of a pH electrode is available for calculations as the variable 'Com-
mand name.SLO.
Range -999.9 ... 999.9 %
Default value 100.0 %
pH(0)
After the slope, the pH(0) is the second characteristic indicator of the cali-
bration function U = f(pH). pH(0) is the x-axis intercept of the calibration
curve, i.e. it corresponds to the pH value at 0 mV. The electrode zero point
pH(0) of a pH electrode is available as a variable 'Command name.ENP'
for calculations.
Range -20.000 ... 20.000
Default value 7.000
