Rinse the conductivity electrode and place into the
1413 µS/cm conductivity standard.
Wait for the conductivity value to stabilize.
a. When the reading is unstable, the stopwatch
icon is shown and the reading flashes.
b. When the reading is stable, the checkmark icon
is shown and the reading is solid.
Once the reading is stable, press the "Enter" key.
The meter will save the second calibration point.
Press the "Cal" key to save and end the calibration.
The "Cal" key can be pressed when either the
Saved or 3rd Point screen is shown.
The average calibration factor value is shown and
then the Calibration Done screen is shown.
The meter will proceed to the main measure mode.
4.1.4 Conductivity Value vs.
Temperature
The following table lists theoretical values for the Eutech
conductivity standards at various temperatures. Actual
values displayed on the meter may vary slightly due to
rounding deviations from the actual conductivity and
temperature measurements.
