Entry of pH value zero point deviation for the alarm
function
If the zero point deviation from the reference zero point
exceeds the value entered here, an alarm (error no. 033) can be
triggered (error activation see page 65).
Ex.: The electrode has a zero point of 7.00 pH (for electrodes
with inner buffer of 7 pH). You enter a zero point deviation
value of 0.05 pH. Then, an alarm can be triggered at measured
zero points <6.95 pH or >7.05 pH.

SCC (Sensor Condition Check)
This function monitors the electrode status or the degree of
electrode ageing. Possible status messages: "Electrode OK",
"Low wear" or "Replace electrode". The electrode status is
updated after each calibration. When the "Replace electrode"
message appears, an error message may be displayed (E040,
E041).
!
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 electrode.

Isothermic compensation
Activate the isotherm compensation and insert the
isotherm intersection point (Uis).
Function off : for Hauser 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
The calibration is only considered as stable, if the deviation of
the mV value does not exceed the given threshold for the set
period of time (length) during calibration.
This function allows you to adjust calibration accuracy and
timing individually to your process.
!
Note!
If your process requires extremely accurate calibration, reduce
the threshold value and increase the period (length) to make
sure that the pH value does not drift.
