Calibration data
Note
This tab only appears for pH and ISE electrodes.
Slope
pH electrode: -999.9 ... 999.9 %, [ 100.0 ]
ISE electrode: -999.9 ... 999.9 mV, [ 59.2/valency ]
Slope of the pH or ISE electrode. This value can be determined automati-
cally with a calibration from the linearized calibration curve or entered
manually. The slope of a sensor that is used by the commands
DET , MET ,
SET , KFT , MEAS and CAL LOOP is available as a variable 'Command name.SLO'
for calculations.
pH(0)
-20.000 ... [ 7.000 ] ... 20.000
The electrode zero point pH(0) is only shown for pH electrodes. After the
slope the pH(0) is the second characteristic quantity of the calibration func-
tion 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 that is used by the commands DET , MET , SET , KFT , MEAS and
CAL LOOP is available as a variable 'Command name.ENP' for calculations.
E(0)
-2000.0 ... [ 0.0 ] ... 2000.0 mV
The electrode zero point E(0) is only shown for ISE electrodes. 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 poten-
tial at log c = 0. The electrode zero point E(0) of an ISE electrode that is
used by the commands DET , MET , SET , KFT , MEAS and CAL LOOP is available
as a variable 'Command name.ENP' for calculations.
