• 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 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 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 “Calibration 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 “Conductivity calibration” menu.
• Use the keypad to enter the custom value with the desired
resolution. Press
Accept
to confirm.
• Fill the calibration beaker with conductivity standard 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.
