calibration
1.
Select the method which uses the electrode to be calibrated.
2.
Connect the electrode system,
see "Electrode connection", page
.
3.
Press 1 Calibrate electrodes in the Electrode window.
4.
Select the electrode from the list.
5.
Press 1 to Run, and follow the messages on the display.
Measurements start in buffer no.1.
The electrode zero pH and sensitivity are calculated at the end of
a multi-point calibration. For a 1-point calibration, only the zero pH
is calculated, the slope comes from the last calibration performed
or is equal to the default value (59.16 mV/pH unit). The calibration
results are saved with the electrode.
To consult the calibration results,
It is recommended to maintain all your standards at the same
temperature. Then the temperature entered at the start of a
calibration cycle is valid for all your standards.
The instrument displays the potential
measured. The displayed temperature is
the temperature measured, entered or is
equal to 25°C according to the
calibration method programmed.
