1. Select the method which uses the conductivity cell to be
calibrated.
2. Connect the electrode system,
see "Electrode connection", page
3. Press 1 Calibrate electrodes in the Electrode window.
4. Select the conductivity cell from the list.
5. Press 1 to Run, and follow the messages on the display.
If you are not using a temperature probe and want to get
accurate measurements, it is recommended to thermostat
your standard beakers at the temperature you have entered
(or at 25°C).
Pay attention to the temperature range of the standard used:
see "Standard (conductivity standard)", page
6. After stabilisation or at the end of the maximum stabilisation time,
the TIM870 calculates the standard conductivity at the measured
or entered temperature. Then, the instrument calculates and
displays the cell constant.
Refer to "Result accepted (Yes/No)", page
7. The cell constant (mean of all cycle results accepted) is saved
with the electrode.
To consult the calibration results,

TitraLab 870 Reference Manual

The TIM870 displays the conductance
measured. The displayed temperature is
the temperature measured, entered or is
equal to 25°C according to the
calibration method programmed.
Accept or reject the result then start a
new calibration cycle (new beaker of the
same standard) or end the calibration.
