• Pour a small quantity of the standard solution into a clean beaker. If possible, use plastic beakers to

minimize any EMC interferences.

• For accurate calibration and to minimize cross-contamination, use two beakers for each standard solution.

One for rinsing the probe and one for calibration.

• Insert the probe in the rinse beaker.
• Swirl probe in this solution. Raise and lower 3 times to fill cell with solution.
• Insert the probe in the second beaker.
• Swirl and tap probe to remove air bubbles. Raise and lower 3 times to ensure representative sample.
• Enter calibration mode by pressing

.

• Wait to stabilize.
• If automatic standard recognition was selected in Setup, a calibration point will be automatically

displayed from the Hanna standard list (84 µS/cm, 1413 µS/cm, 5.0 mS/cm, 12.88 mS/cm, 80.0 mS/
cm, 111.8 mS/cm). The user can also select another standard value by using

and

.

• If User Standard was selected in Setup, a pop-up will prompt for the custom standard value.
• Press

to finish the calibration or

to abort calibration.

• The probe should be rinsed in deionized water.
• Shake off excess water.

Note

: The calculated cell constant will be used for the whole range.

Multi-Point Calibration

• Up to 4 calibration points can be performed in order to

increase the measurement accuracy over a larger measurement
range.

• Select the multi point calibration (see

Conductivity Setup

→

Calibration).

• Repeat the steps from the single point calibration for each

measurement range. The meter will calculate a cell constant
corresponding to each calibration point.

• Press

to exit calibration mode.

Note

: For each range the corresponding cell constant will be

displayed.

CELL CONSTANT CALIBRATION (edited by the user)

• A known value of the probe cell constant can be set by the user for the whole range (see

Conductivity

Setup

→

Cell Constant section). Using a known cell constant is another way to calibrate the meter/probe

system.

Note:

When a cell constant value is used, the solution calibration will be cleared. A solution calibration can
still be made after entering a cell constant value.
