Cal. settings:
JC1 MTC
ATC 1
ATC 2
Select the temperature compensation for the
calibration
ATC = automatic temp. comp.
MTC = manual temp. comp.
!
Note!
The setting is only active during calibration. In meas-
urement mode, the setting selected in GAA1 is valid.
JC2 5.00 mV/pH
(5.00 ... 57.00 mV/pH)
Entry of difference to slope for alarm function
If the entered slope difference is exceeded, an alarm
(error no. 032 / E035) can be triggered (error activation
in field H5).
JC3 pH 1.30
(0.05 ... 2.00 pH)
Entry of pH value zero point deviation
for the alarm function
If the zero point deviates from the reference zero point
by the value entered here, an alarm (Error no. 033) can
be triggered (error activation in field H5).

SCC (Sensor Condition Check)
This function monitors the electrode status or the
degree of electrode ageing. Possible status mes-
sages: "Electrode OK", "Low wear" or "Replace elec-
trode". The electrode status is updated after each cali-
bration. When the "Replace electrode" message
appears, an error message may be displayed.
!
Note!
This function is only available for glass electrodes. If
you are using a glass electrode and an IsFET sensor,
you can use the SCC function without restriction.
However, the SCC function only monitors the glass
electrodes.

Isothermic compensation
Activate the isotherm compensation and insert the
isotherm intersection point (Uis).
Function off : for E+H electrodes
Function on : Only if the isotherm intersection point
≠
zero point of the electrode. The bigger the difference
between isotherm intersection point and zero point,
the bigger the measured error at temperature
fluctuations.
Uis : Enter the intersection point at which the isotherms
of the electrode meet.
!
Note!
When you activate the isothermic compensation the
electrode has to be calibrated before measuring.

Stability
During calibration the mV values may maximally vary
for the given threshold within the defined time range
(length).
During calibration, the mV value may change during
the given period ("duration") at maximum by the stated
amount ("threshold"), so that the calibration is
considered as stable.
Therefore you can adjust accuracy and timing
individually to your process.
