Only pump fluids into the KH Director when the pH electrode is installed and the
fitting is screwed tightly and watertight.
In certain operating situations, it may happen that the measuring cell is not automatically
emptied completely, as for example when canceling a measurement process.
The emptying of the measuring cell can be started completely empty by clicking on the
button
Empty measurement cell completely
. The waste water pump will pump out the
maximum possible filling volume.

Manual KH value measurement
Before starting a measurement, please make sure that the pH-Electrode has been calibrated
and installed correctly and that all dosing pumps involved in the measurement have been
correctly selected, adjusted and calibrated.
Then the measurement can be started via the button

.
Depending on the KH value, a measuring process will take about 10-20 minutes.
DANGER
•
It must always be ensured that there are no air bubbles in the
sample tubes, as these falsify the measurement result.
•
Make sure that the tubes cannot draw air during operation.
•
If you detect air in the hoses, vent them and then perform steps 1-2
as described for the initial measurement.
Please note
