• Insert and rinse the probe in the first beaker in order to decontaminate it;
• Insert the probe in the second beaker;
• Tap the probe repeatedly to remove any air bubbles that may be trapped inside the sleeve.
• Enter in calibration mode by pressing
;
• Wait to stabilize;
• When the automatic standard recognition is selected, the calibration point will be automatically selected
from the Hanna standard list (84 µS, 1413 µS, 5.0 mS,12.88 mS, 80.0 mS, 111.8 mS). The user can
also select the desired standard value by using
and
;
• Otherwise (user standard), the pop-up will prompt for entering the custom standard value.
• Press
to finish the calibration or
to exit calibration.
Note:
The calculated cell constant will be used for the wide range.
Multi Point Calibration
• Up to 4 calibration points can be performed in order to
increase the measurement accuracy on the wide range;
• Select the multi point calibration (see
Conductivity Setup ->
Calibration);
• Repeat the steps from the single point calibration for each
calibration point. 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 introduced by the user for the wide range (see
Conductivity Setup -> Cell Constant section)
Note:
When the user cell constant is used the old calibration (in solution) will be cleared.
