• The main display shows the actual reading, while the secondary level displays

the current temperature and the standard value.

•To change the standard value, press <Cal. point> and the list of available

standard values is displayed: 0 µS/cm, 84 µS/cm, 1413 µS/cm, 5.00 mS/cm,

12.88 mS/cm, 80.0 mS/cm and 111.8 mS/cm.

• The third level displays the status message.

• Press <Custom> to insert a custom value (temperature compensated value).

Insert the desired value using the keypad, then press <Accept>.

•When the reading becomes stable, the stability timer will count down and

<Confirm> will appear. Press <Confirm> to save the calibration.

• After confirmation, the following messages are displayed: “Storing” and “Cali-

bration completed”.

•Press <OK> to return to the “Calibration” menu.

• Press ESC twice to return to main menu.

• Press <Measure> to return to the measurement screen.

Absolute Conductivity

• Select “Absolute conductivity” from the “Conduc-

tivity calibration” menu.

• Use the keypad to enter the custom value with

the desired resolution. Press <Accept> to con-

firm.

• Fill the calibration beaker with conductivity stan-

dard with known conductivity at the temperature of standardization.

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

•Immerse the sensor into the rinse beaker and raise and lower the beaker to

ensure that the EC sensor channels are filled with fresh standard.

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

bubbles. Screw the beaker into place.

• Wait for the reading to stabilize. The stability timer will count down and <Con-

firm> will appear.

• Note the temperature and adjust the conductivity value if needed.

•Press <Confirm> to save the calibration.

• After confirmation, the following messages are displayed: “Storing” and “Cali-

bration completed”.

•Press <OK> to return to the “Calibration” menu.

• Press ESC twice to return to the main menu.

• Press <Measure> to return to the measurement screen.
