found in the bottom of the conductivity sensor. Clean using the small brush from

the probe maintenance kit. Flush with water. A mild detergent may be used to

remove oily coatings. Always flush with clean water after cleaning.

NoteNote

Note For a correct conductivity calibration, the probe shield or the calibration

beaker must be used.

The conductivity calibration menu includes 3

different types of calibration: Conductivity, Absolute

conductivity and Salinity.

The “Conductivity” option allows a single point

calibration with a standard solution selectable by

the user. This calibration is temperature

compensated.

The “Absolute conductivity” option allows a single point calibration with a

conductivity solution of known non-temperature compensated value at the current

temperature.

The “Salinity” option allows calibration with a standard salinity solution.

The 3 calibrations are related, so that each one will calibrate all 3 measurements.

NoteNote

Note To improve accuracy, choose a calibration standard near the sample

conductivity.

Choose “Conductivity calibration” from the “Calibration” menu, select the

calibration type using the arrow keys and press <Select> to confirm.

Conductivity

• Select the “Conductivity” option and press <Select> to confirm.

• Fill the calibration beaker with a conductivity standard (see APPENDIX D - “Ac-

cessories” for choosing the proper HANNA standard solution).

• Pour additional standard into a second beaker to be used to rinse the sensor.

• Immerse the sensor into the rinse standard by raising and lowering the beaker

a few times to ensure that the EC sensor channels are filled with fresh stan-

dard.

• Place the calibration beaker over the EC sensor and dislodge any trapped

bubbles. Screw the beaker into place. Wait for the reading to stabilize.
