7.
Select the electrode Type, for electrodes with pH or mV functions:
•
Single pH - pH electrode (no reference part),
•
Combined pH - pH electrode with a reference part (with or
without temperature sensor),
•
Single metal/redox - mV (i=0) function electrode with a refer-
ence part,
•
Combined metal/redox - mV (i=0) function electrode with a
reference part (with or without temperature sensor).
8.
When a combined electrode has been defined, the instrument will
prompt you to specify if it has a built-in temperature sensor or not.
When a single electrode has been defined, the instrument will
prompt you to define a reference electrode in the Edit
electrode
screen.
9.
When a combined or a reference electrode has been defined,
enter the potential (in mV) of the reference element versus the
Standard Hydrogen Electrode (SHE).
This parameter enables to run calibration with automatic buffer
recognition when working with different reference electrode systems.
On the next page, see the table giving the potential at 25°C versus
the SHE of a few "reference elements/filling solution" couples.
10. When a combined pH or a single pH electrodes has been defined,
enter the internal pH of the electrode (pH int).
11. Press 1 to confirm.
12. Edit the electrode parameters.
