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
reference 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 dened, the instrument will
prompt you to specify if it has a built-in temperature sensor or not.
When a single electrode has been dened, the instrument will
prompt you to dene a reference electrode in the Edit
electrode screen.
9. When a combined or a reference electrode has been dened,
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/lling solution" couples.
10. When a combined pH or a single pH electrodes has been
dened, enter the internal pH of the electrode (pH int).
11. Press 1 to conrm.
12. Edit the electrode parameters.
