4.5 CALIBRATE
Note: Turbidity measurement has been calibrated by the manufacturer — it does not need to be
calibrated again.
Note: It is imperative to calibrate for solid matter measurement (refer to section
The zero point for turbidity and solid matter measurement has been set in the sensors by
the manufacturer.
Installation conditions in the pipes can cause interfering ground reflection when
measuring turbidity, which in turn may cause the zero point to shift. Compensate for this
effect with an offset correction (section
). If there are deviations between
the displayed measurement values and laboratory results that are unrelated to the factors
described above, the slope of the calibration curve can be adjusted using a factor (refer
to section
