Calibration curve with 2 points
As the electrodes are not accessible by the user, they are able to measure only the conductivity of the water
crossing the system.
A 2
nd
point of calibration can not be used when the conductivity is too close to the conductivity of the 1
st
point,
without a risk of miscalibration.
It is recommended to choose the 2
nd
point of calibration with a conductivity close to the maximum.
It is recommended to recalibrate the 2
nd
point of calibration when filters, the RO membrane or the resin is
close to the saturation.
•
Points of calibration: where are the 2 grey
vertical lines.
•
The calibration curve goes from 0 to the 1st point
of calibration. The slope is then adjusted.
•
The calibration linear curve goes from the 1st
point to the 2
nd
point of calibration. The slope is
then adjusted.
•
Above the 2
nd
point of calibration, the values are
adjusted by a shift from the values measured by
the electrode. The slope is the default one.
