slope of an ISE electrode is available for calculations as the variable 'Com-
mand name.SLO.
Range -999.9 ... 999.9 mV
Default value 59.2/Valency mV
E(0)
E(0) is the second characteristic quantity of the calibration function U =
f(log c). E(0) is the y-axis intercept of the calibration curve and corresponds
to the potential at log c = 0. The electrode zero point E(0) of an ISE electrode
is available as a variable 'Command name.ENP' for calculations.
Range -2000.0 ... 2000.0 mV
Default value 0.0 mV
c (blank)
c (blank) is the third characteristic quantity of the calibration function U =
f(log c). It reflects to a certain extent the curvature of the calibration function
at the lowest concentrations. This curvature is caused by the influence of so-
called interfering ions. If the concentration calibration is carried out with less
than 3 standards then c (blank) will be set equal to zero. The parameter c
(blank) is available as a variable 'Command name.BLV' for calculations.

Specific calibration data for conductivity sensors
Cell constant
Cell constant of the conductivity sensor. This value can be determined auto-
matically with a calibration or entered manually. The cell constant is available
as a variable 'Command name.BLV' for calculations.
Range 0.001 ... 500 /cm
Default value 1 /cm
