4.1.2 Conductivity Calibration
Procedure
Ensure the active measure mode is conductivity.
Press the "Cal" key to start the calibration.
Rinse the conductivity electrode and place into the
conductivity standard.
Wait for the conductivity value to stabilize.
a. While the reading is stabilizing, 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, accept or edit the
displayed conductivity standard value:
a. To accept the conductivity standard value,
press the "Enter" key.
or
b. To edit the conductivity standard value, press
the or key to change the value and then
press the "Enter" key to save the value.
i.
Press the key to increase by one
digit. Press and hold the key to
quickly increase.
ii.
Press the key to decrease by one
digit. Press and hold the key to
quickly decrease.
Proceed to the next calibration point or save and
end the calibration:
a. To proceed to the next calibration point, repeat
steps 3-5.
or
b. To save and end the calibration, press the
"Cal" key.
The meter will display the calculated calibration
factor value and then proceed to the main measure
mode.
Note: Press the "Measure" key at any time to abort the
calibration and return to the main measure mode.

4.1.3 Conductivity Calibration
Example
The following is an example of a two point conductivity
calibration using auto-recognized 84 µS/cm and 1413
µS/cm conductivity standards.
Press the "Cal" key to start the conductivity
calibration. The nominal cell constant value is
shown.
Rinse the conductivity electrode and place into the
84 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 first calibration point and
proceed to the next calibration point.
